The well loved Model 3 gets a new power supply

- Ahh, this beat up old Model 3. It's not just well loved from the previous owner and all their notes and stickers, but because I love it to.
But it started playing up recently, so it's time for a new power supply!

🎶 "Ladies go crazy bout a sharp dress man" 🎵Looking good dude!
"G'day Cave Dwellers!"... RMC might have to watch out, his title of Most Snappily Dressed Retro RUclipsr is under threat. 😀
Ah yes, the black suit is very appropriate given this week's news. 🙂
I always appreciate a PSU upgrade, great way to protect and future proof these old machines!
Happy Septandy well dressed Jason!
you and that tandy are looking very professional!
"G'day Internet!" Very nice kit and a great way to future proof your TRS-80 Model 3 computer.
Professional Jason looks cool as hell!
Wow, I'm impressed! You did that mains chassis wiring without burning the house down even once! A task which nanny state would have us believe is borderline impossible to do without the correct qualifications and certifications. Certainly on par with handling firearms, transporting radioactive waste, or wiring an Ethernet cable. All of these things are clearly of equal danger in the eyes of nanny state.
Seriously though, this does seem like a neat solution. I was looking at a similar Mean Well power supply to use in my Apple II clone, but I ended up going with a TFX power supply, mostly because it was a neater fit. Unfortunately there's no nice breakout board like that for my machine. It used a weird power connector, not the "standard" Apple II connector, so it took a while to figure out what it was so I didn't have to solder onto the board. Turns out it uses a JST connector that's still manufactured some 38 years later. A quick order placed on the JST website and I had the connector and contacts within a few days.
Every Tandy special is a significant occasion. Formal attire is therefore quite appropriate 👍
Impeccable looking, Mr Lurch. I feel terrible watching this in cotton home-wear pants & t-shirt.
I saw those snazzy duds and I thought I was watching RMC for a second.
Where the heck was this video 2 days ago? I just spent a few hours messing around with putting a meanwell in my Model 4 dealing with clearance issues. lol. I never thought to put it under the floppy drives :) I seriously love your channel and your videos. Keep up the great work.
About your dressing style (before seen you video): it makes you look much more than just a "Mr Lurch". Anyway, if it is due to the recent circumstances or if it is for whatever personal reason, wear it if it makes you feel comfortably at any time. Many, many thanks for ALL the contents you deliver as a gift to us during all these years.
I thought the TRS80 at least deserved a dinner jacket!
"Cause every girl crazy 'bout a sharp-dressed man" 🎶🎶
Haven’t seen one of these in years! When I was in jr high school in 93-95 we used these exclusively for typing practice. The main computers were Mac LCII’s and LC520’s.
Can't say why, but I chuckled at this grunt. 9:56
Ahh, I forgot it was now Septandy! And good timing Mr Lurch ... I finally got my US CoCo2 out to fiddle with it, and the first thing was pulling the transformer out to figure out an Aussie 240V replacement. I didn't realise I had to dress up for the video though ... still wearing my old jumper ;) /Brett
I think Mark did that conversation last year.
Septandy!!! One of my favourite months!!! By the by, you polish up nicely. :)
Excellent work!
For a moment I though you were going to say you were morning the death of the Queen
Looking good in suit :)
Excellent. Same one you can use in a 1541.
Got me thinking of upgrading my machine, a model 1 in a model 4 case.
Which brings me back to my favourite peeve with US equipment, black for active... I usually rip that out and put in standard brown & blue etc, lest I mistake that thin black and white as something else and give myself a shot of 240V in the future.
Actually for that longish run, I would use standard three core flex, then is will really look like power wire.
I would also put something over the back of that power switch, it looked like bear solder joints in the video, so easy to brush your hand over it whilst servicing your machine. Even a liberal coating of hotmelt glue is better than nothing.
definitely put some washers in there if your going to use the vent holes :o
Amazing that tiny MW PSU replaced the 2 massive by comparison original supplies.
The original PSUs with a dual floppy machine would see the display duck and weave when the disk drive motors were started. This one is probably much better regulated. I replaced the PSUs in my long gone 4 internal floppy MIII with a single beefer and cooler running 5V/12V power supply. The - supply for the DRAM and RS232 board were done with separate charge pumps based on 555 timers. The DRAM needs very little current and the sag on the one for the RS232 was low enough that it didn't cause any problems. These days you can buy isolated 5mA PCB mount modules in any low voltage you want for a few dollars.
I will indeed comment now! Your work attire is quite good. I often aspire to dress nicely, but in the morning I can't bring myself to the effort. :( I love your videos, no matter what you wear though.
A dandy fixin a Tandy
Looking sharp
Relaxed office dress... Not "professional" where I grew up. (Anchorage, AK.) Generally, professionals wear ties... but may or may not wear a suit coat and/or lab coat (when appropriate). Still, looks sharp. I've not put on a suit in almost 20 years now.
Looking good, my friend. Suddenly I’m feeling underdressed. Ha!
Nice threads and great work. I forgot about Septandy. Will have to dust off the model 1 and get it running again.
snazzy attire man :)
Professional Jason is snazzy indeed! This is becoming a posh channel. ;)
Professional Jason is very smicko!
Excellent work and addition to your TRS80! Thanks for sharing
After seeing your video, I think I'm going to replace my Model III PSU with a MeanWell instead of recapping it.
I like that thin screwdriver. Got a link for it?
Snazzy!
Excellent. I'm sure i'm going to need to do this at some point. I think i'd rather figure out a way to use the existing power supply locations than storing under the disk drive.. I guess something to think about. Thanks for the vid!
It possibly doable. However the Mean Well is just a bit wider and longer than the four screw points where the original PSU’s mounted. And if turned 90deg and mounted where the FDD PSU was, it fouls on the CRT. And is too tall to mount where the rear PSU is. I tried all kinds of other mounting options before deciding on where it ended up.
👍
Oooh. I thought you were wearing black for the passing of the Queen. LOL.
So Clive Sinclair did have a son... 🤣🤣🤣
Desperately need a new PSU for my TRS-80 Model 4P. Do you know if a similar replacement is available through Ian? Didn't even see this board on his site.
When it comes to Ian, always best to email.
Just wondering where the ‘Mr lurch’ nickname came from, is there a story behind the name?
He's tall a.f
Sometimes you feel like a nut...
I felt I was a bit underdressed. And like someone else mentioned, I thought perhaps I was watching a different channel.
Who are you and what have you done with Jason??? Well, as long as it's a good video...
Isn't SepTandy about taking on a project where everything goes to hell in a handbasket, frantically trying complete it within September as one complication chases another, and then barely finishing the upload at the 29th or 30th? I think you're doing it wrong.
You still need a suit at work? How old fashioned. Not even upper management wears a suit anymore in our it company
