With regard to the index hole, we used to use a paper punch to CAREFULLY make new index holes on the other side. Worked like a charm. I think I still have some of the disks I made back in the day :)
The first computer I used as a programmer. A friend took me to his work on a Saturday to see the computer. In half an hour I learned to edit code in Basic (that in TRS89 looks like a mix of VI but line oriented). During the week I wrote (on paper) two programs. A Pong and a Mousetrap. We went again next week and typed the programs. That work first time (as I remember). He got impressed and in a week or so I was working there. I had learned Basic from a 15 part course on a magazine that I made my father subscribe on an electronics fair: Microsistemas (in Brazil). I am specially fond of this model because of that.
Wow, fantastic! The Model I was my first foray into computing when I was a wee lad of around 5 years old. My father bought one in 1978-79 time frame. I think he still has it in his basement somewhere. He had the expansion interface, two floppy drives, RS-232, parallel, sound, the works. I would have loved to see the restore on this. So now we need a video series on your restore of the Model I, the rest of the Model IV, the Tandy 1000 TL, etc. I can't wait to see more!
@@lohphat Since this comment, my father has passed away. The next time I get out to CO, I'm going to bring the Model I back to see if I can restore it. It should make an interesting project. Yep, it launched my tech career as well, for better or worse.
I've written boot disks on a 3.5" floppy for my 1987 Tandy from Windows XP. Windows didn't seem to care what was on the disk. That's why I loved Windows XP - it never questioned me. It took my word for it.
I know this comment is 5 years old and you may not reply, but how did you actually write them? I get the whole attach them to a computer and throw files onto it but what drive did you use? All of the USB Amazon ones seem like they won't actually write to a blank floppy disk. So confused.
Back in the olden days (5 years ago) I still had a floppy A: drive in my ancient desktop. If I recall correctly, I downloaded the disk image and copied the files normally. In this modern era, you can get an IEEE to USB device to connect an old floppy. My Tandy 1000 apparently uses a standard DOS and had no compatibility issues.
We used to slip a piece of paper on the pack side, under the plastic from the center of the disk, then slide a hole punch over that and make an index hole to allow the disk to be read on the flip side in the TRS-80. Give it a shot!
I watched this a long time ago but didn't have a TRS-80 at the time. I now have a 4P coming and have been playing with an emulator in anticipation. I'm glad, after rewatching this, that all those DSK files I have are actually DMK as I've been using ImageDisk for a long time and this means I don't have to learn another piece of software or set up another computer just to make physical TRS-80 floppies. Many trhanks.
Wow. Really enjoyed the story that came with your TRS-80 floppy disk tutorial. I'd also love to see a more detailed look at the machine - additional details on the work you did.
After a seven month restoration effort for my own Model I, I found getting decent boot disks and transfers to be the final challenging aspect! There's an alternative approach that some may find more accessible if they can't find another vintage PC with compatible disk drive for writing via IMD. There's a cassette bootstrapper by Jurgen Bussert for Model I and Model III including all major versions of TRS-80 DOS. Basically you play the bootstrapper audio to the TRS-80, then play one of the DOS variants which handles formatting the disk and writing all 35 tracks via cassette. The downside is it takes around 40 minutes per attempt and any failure along the way will result in a redo. In either case I was successful with my setup in creating each individual DOS disk purely from audio transfer!
Hi, Adrian. The 'deleted address mark' was used to specially format the directory track. On TRSDOS (and compatibles) there was one whole track dedicated to the directory, so you could run out of directory entries before you used all the disk space. If you ever find a PDF for "TRS-80 Disk and other mysteries" it'll teach you more than you ever want to know.
THANK YOU, Can't even begin to tell you how many hours of frustration you have saved me and others in needing this bit of info... There's literally _no_ step by step guide out there, Nor convenient stuff like ADTpro for the apple series
Can you (or anybody) go over the process at 4:37 where you make the dsk files that specific size that works with imd? how do I mount a disk copy utility into the emulator and such
I am still catching up on the hundreds of videos you've put out, so even though this one is 3+ years old now, I have to say that the TRS-80 Model I was my first home computer and I am jealous that you have such an awesome one! ;) That brings back a lot of great memories for me. Hopefully you'll have it in one of the #SepTandy videos for 2021/2022? :D
Awesome rescue and restoration! There is another way too, perhaps you will like as well: You can use the Reed Model III emulator on your PC, mount the PC floppy drive as a TRS drive, format the floppy from the emulator, and disk copy from the emulator. That floppy is now usable in the Model I. IMD is not needed.
back in the early 90s, I had a CoCo3 with OS9. I managed to tweak the device drivers so that I could use the drives from a T2000 (720K 5-1/4) and others like 1.2MB, 1.44MB drives. Hope you get a Hard Disk for the TRS80 so you can increase your storage. GOOD LUCK!
I have created Model 4P disks directly on a PC using a Mode 4P emulator and the 5.25 disk drive on the system. You can mount the physical disk similar to the virtual disks and format copy and everything else you need to do.
I just set up my test machine to verify things. The computer I am using is an AOpen Pentium 100 running in DOS mode. Install the emulator and using F9 you can toggle between the command screen and the disk drives. TAB key lets you select drives. Once you are highlighting a drive press enter and you can now browse to the DSK image you want to load. Loading FDD1_360.dsk will select the physical floppy drive on your computer. By default the emulator enables Drive 0 and 1, To enable the other drives use the command system (drive=2,enable) followed by the enter key. Do the same for drive 3 if you like. You must have had an OS disk loaded in drive 0 to get things going. I loaded LSDOS 6.31. It has Diskcopy on it. Now to make a copy of the disk image you can load the source in drive 0 or 1. I used drive 1 and issue the command Diskcopy :1 :2. Make sure you have a single sided floppy in your drive and it will start writing and verifying as it writes the disk. I did this using the ROM image for a Model 4P. It creates a disk that can be used in a real Model 4P in this case. When doing this for other models, make sure your ROM image matches the OS version to ensure compatibility.
I figured that out about the index holes with my Coco that worked the same way. I got good at punching them out with a hole punch to make them DS. It was not too hard to get the hole punch in between the jacket and the media, and I made a paper template. Mostly because I was a kid who wasnt a baller, and well, because I could.
Makes me sort of sorry I don't have mine anymore. I had the full setup too - Model 1 Level II 16K, EI with full RAM to bring it to 48K total, serial, parallel etc. Disk drives, speech synthesizer too.
Well it was stored in my parents house. I'd moved on to PC's at that time. Starting with an IBM XT Clone followed by many x86 based systems. Now on an x86-64 i5 based system running Windows 10. I think my parents trashed the machine. No sense asking now as they're all dead.
At last, another video from you! They actually have companies that recycle floppy disks to be reused. One of their biggest customers is the U.S. government.
You could very easily make flippy disks. Just needed to take the disk out of a bad floppy and then use that as a template to mark where to hole punch the index holes on the other side. As long as you were carefull not to touch the disk surface, it worked fine. I did that all the time when I owned one of these (was my first computer).
Wow. Nice to see this. My brother brought a Radio Shack TSR 80 back from the US, so I know it. But that game :D "Eliminator" was it a copy of Defender or was it a precursor?? and thumbs up btw. nice to see nostalgic and old school stuff, fixes etc and see that you can still make it work. :)
I was always wondering if you could make a disk from scratch. I mean surely all it would take is some very thin plastic as the case, some of that anti-static laundry cloths (bounce) to line the insides and a sheet of thin magnetic stuff cut to shape as the storage medium.
You can punch index holes using a hole punch on the other side using a template to mark where to punch them. A jacket from a bad disk works fine for this. Just mark with a pencil lightly, and punch just the jacket on both sides. DO NOT punch through the mylar.
That sure takes me back. I'd really like to know a good way to get old data OFF of the original disks (+1 for Newdos80, BTW) and onto a modern PC. The model 3's/4/s are long gone, but I have boxes of 35 year old disks containing personal writings/programs/old online correspondence, etc. Wonder if anything is even readable at this point. BTW, I recall brute forcing extra index holes with a single hole punch in a pinch. LOL
Can you make these IMD files available somewhere? I'm having a heck of a time with the conversion process from DSK to IMD and I can't seem to find any IMD images out there on the web for TRS-80 Model 1.
Thanks for the very useful video. I'm really interested in the heroic efforts to restore the Model 1 from the rust & mud. Have you any other videos or before/after photos from that restoration?
Funny how this was one of the best ways to get real software off of the internet onto a real TRS-80 disk just 4 years ago. Now there are much easier ways. A Gotek with Flash Floppy firmware and a real TRS-80 disk drive are all you need now in order to make real disks for the TRS-80. A FreHD hard disk emulator is another way. Bartlett Labs MIRE and MISE are another way. An HxC floppy emulator is another way. Another slower way is to transfer the files directly using a serial connection, null modem adapter and terminal emulation software.....slow, but can be done. No need to have a vintage PC on hand any more.
Yeah, those old floppy drives used what is called CAV (Continual Angular Velocity). They spun at the same speed regardless of which track the drive head was on. There is a sensor in the drive that detects the index hole, which marks the angular start of each track (in other words, where sector 1 should start). The hardware knew when it was at the correct sector based on the amount of time that had passed since the last time the index hole passed the sensor. It also was used to make sure the disk was spinning at the correct rpm. Commodore and Apple decided on an encoding scheme called GCR (Group Code Record), which did not need the index hole, because each sector started with a "header" block that included the track and sector number, followed by a data block. So if you told it to read track 18, sector 10, the drive simply had to move to track 18 and read the headers (skipping the data block) until it found the header block for track 18 sector 10. And there you have it... the reason why the Tandy needed the index hole, and Apple and Commodore (and Atari) didn't. I over-simplified it a bit; obviously there's a lot more going on behind the scenes, but I didn't want to write a huge wall of text. :)
I appreciate the response! This is something I'm going to learn more about. Recording media and computer memory has always been an interesting topic to me. :)
Does anyone know how I would go about making a TRS 80 model 12 (a variant of the model 2) boot disk? The model 12 uses 8 inch floppies and I believe the model 2 and variants have a completely different architecture to the other TRS 80 computers.
Adrian Black LOL I wouldn't worry about it. I suppose if you were making one from scratch you would have said "How to create a 5 1/4" floppy disk". A little error in translation on my part.
Good video Adrian. Very impressed how well that system cleaned up. One question. It's known that not all old motherboards with onboard disk controllers of the 486. P1, and P2 vintage have disk controllers that can write single density. Some do and some don't. Does using the /S switch in Imagedisk somehow negate that through software trickery, or do you really need a motherboard that can write single density?
I'm curious. In the DOS machine used to write the disks, do you actually have all 3 floppy drives connected somehow, or are you just switching between them as needed internally?
I have a over clock mod on my TRS-80 model I level 2 48k computer. I've only seen this mod on one other model I. You can switch it on and off by Out 255, 1 or 0. Has anyone else seen or have this mod?
A monochrome, textmode clone of Defender... _with parallax scrolling_ ... There really is always something new and amazing to find in the world, isn't there.
Great clip, thank you!!! But could anyone plz place a link here where to download an DSK-Image of a Model I Single Sided 40 Tracks with exactly 128k (or 35 Tracks with about 109k)? I have looked a long time fo it but I didn't find some thing like that. Thx a lot!
Disks for the Model I are 35 track, 10 sectors, single-density, single side, soft--sectored, Should not here that Tandy/Radio Shack disk drives were only 35 tracks for the Model I. The Model III which superseded the Model I, had 40 track, double-desnsity disks/drives.
I thought it was an arcade machine or something playing background music. When he cut to the TRS-80, I was slightly surprised it wasn't running a game already.
Wow. That's an excellent tricked out system you've got there. Glad it survived and you managed to get it working so well. Have you heard of the FreHD (vecoven.com/trs80/trs80.html) hard disk emulator? It's a great way to transfer files back and forwards between a modern machine and a TRS-80. Nothing quite like the sound of an old floppy though. :)
Very nice video and a very nice system :) Just a quick tip ,on your windows 10 computer you can use a program called OBS (Openbroadcaster) it's freeware and will allow you to record the screen and a mic at the same time that way you don't need to use a camera to record the screen and it will make editing easier and look a bit better :)
Very cool video I came to this ome from your other trs-80 vids I have a trs-80 also it has the keyboard built into it but no monitor I'll sell it cheap if your interested send me a dm
I have this machine minus the extra memory. Star Fighter was the BEST game on the TRS-80 imo. I have a small YT vid on my channel of the game, plus you can download an emulator, games and instructions I put together here: x1337x.eu/torrent/803017/TRS-80-Emulator-ROMs/
DO NOT EVER RUN OLD FLOPPY DISKS on A MODERN O.S.. The modern operating systems will try to constantly write to the old disks (for updating the last assessed time) and ruin the disk. Use the oldest MS DOS/DOS system you have that works with the disk. The older OS does not constantly log info.
I don't want a TRS-80, but I really love the fact that other people want to have one and show it off on RUclips!
That brings back some happy memories from 1979!
With regard to the index hole, we used to use a paper punch to CAREFULLY make new index holes on the other side. Worked like a charm. I think I still have some of the disks I made back in the day :)

Great job!
Old computers are wild. Thanks for sharing this.
I used to use a hole punch on Single Sided TRS-80 disks to make them work as double sided.
Nice!

Nice job. I did not know that an old PC is capable of writing the TRS-80 disk format. I am going to try this , thanks for posting!
Awesome video. Thanks for the info.
Back when I had a model I we made single sided disks into double sided using a scissor to make the notch and a hole punch to make the index hole.
Makes me sort of sorry I don't have mine anymore. I had the full setup too - Model 1 Level II 16K, EI with full RAM to bring it to 48K total, serial, parallel etc. Disk drives, speech synthesizer too.
Well it was stored in my parents house. I'd moved on to PC's at that time. Starting with an IBM XT Clone followed by many x86 based systems. Now on an x86-64 i5 based system running Windows 10.
I think my parents trashed the machine. No sense asking now as they're all dead.

I really miss those machines..
Well done sir. Just got a mint model 4
Did you make videos on the restoration? Would love to see those. Would also love to see more about the video board/monitor mod. Great video!
Try something like Ospho on the rusty case to prep the metal for painting.
I was always wondering if you could make a disk from scratch. I mean surely all it would take is some very thin plastic as the case, some of that anti-static laundry cloths (bounce) to line the insides and a sheet of thin magnetic stuff cut to shape as the storage medium.
These things are tough, I also have a Model 1 which still works, same expansion box but the monitor is a bit different (looks more like a TV set).
If you listen closely, the RF noise from the older computers is in the soundtrack.
What a cool system!!!! You need to do a "Trinity" video with this, the PET, and the Apple ][ running the same thing - maybe 8-bit Guy's robot game?
hello please help me my old little friend says Syntax error
You can punch index holes using a hole punch on the other side using a template to mark where to punch them. A jacket from a bad disk works fine for this. Just mark with a pencil lightly, and punch just the jacket on both sides. DO NOT punch through the mylar.

Somewhere i have TSDOS disk manager for the models 1,2,3. Must find.
All I have is the original Shugart SS 35 track drives, and no DD card, will this process work with them? or only the 40 track drives?
Could this be replicated on dosbox?
The monitor you were showing the emulator running on... seems maybe a bit dusty.
You can hole punch a new index hole - I do it all the time :) also where is the reinforcement hub on the diskette? - love the show!

P1, and P2 vintage have disk controllers that can write single density. Some do and some don't. Does using the /S switch in Imagedisk somehow negate that through software trickery, or do you really need a motherboard that can write single density?
tho i will say shame on you for not documenting the cleanup of the model 1
Please do! I like teardowns.
So the TRS-80 disks hold 128K unformatted and 87K formatted.
Found this very interesting but I too thought you were going to show us how to make new floppies. Might want to alter the title.
I'm curious. In the DOS machine used to write the disks, do you actually have all 3 floppy drives connected somehow, or are you just switching between them as needed internally?
Sorry Adrian, one question... This computer runs CP/M Operating system??
Wow so funny this was my 1st computer cool to see one working again
I have a over clock mod on my TRS-80 model I level 2 48k computer. I've only seen this mod on one other model I. You can switch it on and off by Out 255, 1 or 0. Has anyone else seen or have this mod?
A monochrome, textmode clone of Defender... _with parallax scrolling_ ...
There really is always something new and amazing to find in the world, isn't there.
Nice. Now I just need a TRS-80 to add to the collection :)
Yeah, but a Model 1 goes so well with my Dick Smith System 80 and Apple II :)
Very interesting. Keep them coming
Great clip, thank you!!! But could anyone plz place a link here where to download an DSK-Image of a Model I Single Sided 40 Tracks with exactly 128k (or 35 Tracks with about 109k)? I have looked a long time fo it but I didn't find some thing like that. Thx a lot!
My first computer.
Disks for the Model I are 35 track, 10 sectors, single-density, single side, soft--sectored, Should not here that Tandy/Radio Shack disk drives were only 35 tracks for the Model I. The Model III which superseded the Model I, had 40 track, double-desnsity disks/drives.
i want one of those, sadly i cant found one in my country
Can also use a floppyemulator to do this.
If one wants floppies, one could emulate a floppydrive and then copy the files to a real floppy.
What is this eerie noise in the background? EMI from the TRS80?
And I already thought your TRS80 is trying to tell us some secret message xd
I thought it was an arcade machine or something playing background music. When he cut to the TRS-80, I was slightly surprised it wasn't running a game already.
Wow. That's an excellent tricked out system you've got there. Glad it survived and you managed to get it working so well. Have you heard of the FreHD (vecoven.com/trs80/trs80.html) hard disk emulator? It's a great way to transfer files back and forwards between a modern machine and a TRS-80. Nothing quite like the sound of an old floppy though. :)
Awesome, a lot of steps but current computing is easier.
Great tutorial!
matthew reed? as in, my friend made this?
Cool background beeps 😂
Great video! :)
Millennial sees loading bar that goes to up to 7 but ends at 4.
Basically you have to know when it's supposed to finish.
Makes sense but still just...
the payload starts from 12:45
Very nice video and a very nice system :)
Just a quick tip ,on your windows 10 computer you can use a program called OBS (Openbroadcaster) it's freeware and will allow you to record the screen and a mic at the same time that way you don't need to use a camera to record the screen and it will make editing easier and look a bit better :)
Adrian Black that's understandable :) and to be honest I like your videos so it's all good.
Pretty cool indeed. Thanks for the video Adrian :)
My conclusion: you are old, friend.
you should get yourself a cheap grip for you phone. just search amazon for phone grip. no complaints just trying to help.
Quite dusty screen...
Very cool video I came to this ome from your other trs-80 vids
I have a trs-80 also it has the keyboard built into it but no monitor I'll sell it cheap if your interested send me a dm
I have this machine minus the extra memory. Star Fighter was the BEST game on the TRS-80 imo. I have a small YT vid on my channel of the game, plus you can download an emulator, games and instructions I put together here: x1337x.eu/torrent/803017/TRS-80-Emulator-ROMs/
DO NOT EVER RUN OLD FLOPPY DISKS on A MODERN O.S.. The modern operating systems will try to constantly write to the old disks (for updating the last assessed time) and ruin the disk. Use the oldest MS DOS/DOS system you have that works with the disk. The older OS does not constantly log info.
Clean your monitor! Nice video though.
OH Lord the TRASH 80! Good for a Boat anchor and door stop.
Misleading title. A diskette was formatted. No disk was made in this video.
I used to know all this shit....waste of time lol. Did NOT help me in my later life!!!
