- At the conclusion of the Retro Challenge I review what I've achieved in the last month restoring a pair of Osborne 1 portable computers from 1982.
For more details about my Osborne restoration, see my blog at www.richardlox...

Thanks very much for making this video. It's great to see an Osborne 1 in full swing. You really persevered in some of this, including the process for transferring files to/from the Gotek disk images, and also the binary hacking of the adventure game programs to get the screen codes perfect. Nicely done!
Good Retrochallenge!
You should ask The 8 Bit Guy or LGR for some troubleshooting tips. They really know everything there is to know about retro computers so I'm sure they could help.
Do you have any experience working on an Osborne Executive? I don't know how similar the circuitry is to the Osborne 1, but I just bought an Executive and I'm having some problems with the internal monitor.
I opened the computer because the front cover was a little loose and there was an intermittent problem with the power turning off and restarting if I moved the computer. I saw that there was a couple of jumper wires on the main board - one was just a clip lead connected between two chips! It came off and after I put the computer back on, the image on the internal monitor is slowly rolling like the vertical sync isn't working. I can't imagine why someone would "fix" an earlier problem by just using a clip wire, but it can't be a coincidence that the internal monitor started having problems after I disconnected it. Please help if you can!
Totally awesome video, i have an Osborne myself which im planning to do some videos with, this will mostly be software, mainly because mine works :P
Is it posibly to download your altered version of the game somewhere?
Yes, there's a zip file on my corresponding blog post here: www.richardloxley.com/2018/04/28/osborne-restoration-part-17-text-adventure-games/
There are also lots of other posts about the Osborne. The index page is here: www.richardloxley.com/2018/03/30/retro-challenge-2018-04/
Thanks so much for the video. Got my start at 14 on this computer. Had the 14.4 modem and 99% of my time was spent dialing into pbx's and bbs's all over the US before the internet as we know it today. Self taught CPM, learned spreadsheets and navigation around (probably illegal) bbs's and 'other' systems. My favorite memory though was the adventure game. Any chance that's available to play now anywhere?
Found it!

@@dogcat2347 Sorry for my delay in replying! I was about to say, almost all the early adventure games were derived from Colossal Cave Adventure. There were lots of subtly difference versions, but any of them should provoke the same nostalgia. I first encountered it as Pyramid 2000 on the TRS-80, which was the same cave adventure, but supposedly in the catacombs under a pyramid! Have fun adventuring :-)
Are the ones with the strip saying "Osborne-1" on the side rev A or rev B?
The original revision had Osborne 1 on the side, with catches on the side and a ribbon cable for the keyboard. The later revision (commonly called the Osborne 1a in some literature) has no writing down the side, catches on the top, and a coiled cable for the keyboard.
I have two of the Osborne 1a which I restored in my videos, and recently got an original Osborne 1, although I haven’t had a chance to restore that yet.
@@richardloxley Thanks!
I didn't watch the video to the end (I own two Osborne One and I repaired both, so I already suffered on that and I can't see other suffering LOL).
I'm just writing you a note because I've seen on your site you hadn't bootable floppy disks for it. Maybe it would be useful in the future or for any other with the same trouble.
I discovered how to format and write floppy disks for the Osborne One using an old IBM XT compatible.
*** Specs ***
- the Ms-Dos PC must have 360 kB FDD (I didn't succeed using 1.2Mb FDD)
- the Osborne One must have Double Density drives (it doesn't work with Single Density drives). One of my two Osborne One has the internal board for Double Density.
Then you must find the "22disk" for Dos (look for 22dsk142.zip on the web or get it from this page: www.gaby.de/edownl.htm).
unzip, run cmenu and choose OSB2 to format for the Osborne
To write an image on a real floppy use Image Disk 1.18 for .imd images (get it at web.archive.org/web/20130330052932/www.classiccmp.org/dunfield/img/index.htm) - Choose double step = off, 40 tracks, double side = on) - get the images from web.archive.org/web/20130323080107/www.classiccmp.org/dunfield/img54306/system.htm - remember, SSDD disk like "Osborne 1 Double Density CP/M" (web.archive.org/web/20130323080107/www.classiccmp.org/dunfield/img54306/d/o1ddsys.zip)
(Note: for .td0 images must use Teledisk instead)
Hope it helps!
Cheers from Brazil

Nice one - it’s good to have other options!
I now have three Osbornes and have fully repaired the first two I got. I’ve got a Gotek/FlashFloppy drive in one so that’s now my go-to way of transferring files to floppies.
I do also have an IBM XT so your information may prove useful in the future :-)
