Common trick. Power up through an incandescent light bulb first to limit current while caps reform.

Motherboard could be a ProcesserTech or Godbout (CompuPro) product.

S-100, the original open architecture!

Fantastic & informative video! Thanks a million. I don't have any of the old gear any more, but have a few virtual machine programs on my Win11 box nowadays (VMware and 86Box). As I did run a bit of CPM stuff and early MS-DOS back in the '80s and '90s, I'd like to be able to 'build' a couple of virtual CP/M machines in one of those emulators, so some of the techniques you used have put some ideas into my head to try out. But, you also mentioned about using emulators for CP/M in the video. Did you get any further with that idea? What I'd love to be able to do is install CP/M on an IBM-type VM with a couple of virtual floppies and a virtual HDD (I understand that can be no more than 8MBytes). I did manage to get one working, but when I tried to create virtual floppy disk images and/or transfer the .com/binaries of programs like NewWord/WordStar and dBase over, I failed miserably. A video showing how to do that would be a god-send and will probably attract others who are into retro-computing but like me don't have the old kit!

Nice buold for a.controller box, not for diy controller build

That's cool nice find

Hi Mike, Have you have dumpster diving again??? :) New 'old toys' are the best! Great find! Thumbs up! Jim

Nice find Mike! Seeing that kinda makes me want to get my TRS-80 Model III out to play with again. ;)

In Nov. 1976, I bought a new IMSAI 8080 kit and assembled it. The kit was essentially bags of parts and bare circuit boards. The power supply was capable of 22A @ 8V, IIRC! The mother board could hold up to 22 S-100 connectors, but I only had 11 installed. I bought a separate 16K memory, originally with 4K bytes. I also had a multi I/O card that had a serial port, parallel port and cassette interface. The serial and cassette interfaces used timing loops, rather than proper controller chips. I also had a separate video card that initially displayed 16 lines of 32 characters, but later 64 characters, after I replaced the portable TV I had been using for a display, with a security monitor. I also designed and built from scratch an 8 port serial card, though I only had 3 UARTs on it, the same 8250 that was used in the IBM PC. I actually found a bug in that chip that the manufacturer was not aware of. Also, the same connectors used in the S-100 bus, I later found in Data General Nova & Eclipse computers. I started working as a computer tech about a year after I got my IMSAI and was working on DG computers. Back in those days you not only had to know the hardware, but also the software. I bought a monitor, assembler, editor and BASIC from a company called Scelbi. I had my computer connected to a 300B manual modem, amateur radio RTTY and a Teletype model 35 ASR (punch tape & reader) and wrote the software to connect all that.

This is Wickid Awesome!@ New Sub; Dryden, Mich. I would love to Tinker and Build one of these Home Mini-PC Projects that Recreate these, but my 40+ Untreated AHDH <--- and apparently Dyslexia... Have a Hard time keeping on track LOL

Hi Mike, GREAT find! Are we going to see a video about the big CNC lathe? Thumbs up!! Jim

Excellent tutorial!

Hi Mike, GREAT find! Like a little kid at Christmas! Looking forward to watching you install them - hope they both work just fine! Thumbs up! Jim

in 1979 in my technical writing course at the University of Florida as a requirement to my Electrical Engineering degree I chose the subject of computer busses including the S-100 bus for my papers. The writing instructor was absurdly excited by my writing style, and I aced the course.

Awesome find!

Hope to see you implement those, I have them both and will be working with them some day.

Looking at the sound card, it looks to be in good condition also, but it might need some work.

Looking forward for a follow up video

Looking at the video board, it looks to be in very good condition.

I miss my local Radio Shack and getting the Radio Shack catalog every year

Nice that was my 2nd computer in the 80s.

9:59 Sounds like me. I would go into the RS store and type programs in the TRS-80s so something like animated background "graphics" would be running on them. My first programing experience was a Skilcraft RIC-920 (I had a rock collection), then Bally BASIC "game" cartridge for the Bally Astrocade, then TRS-80. In college and then professionally I did most of my programming with various languages on DEC machines (VT100s, VT400s, etc) using OpenVMS networked to VAX mini-mainframe servers.

Where does the Radio Shack branded inventory come from? Is it a case where inventory is bought and then the franchise owner pays to have the products packaged in RS packaging?

any updates? its already an awesome machine but definitely even better if you've implemented disk I/O?

i am loving your channel so far! and the fact you sound like peter Griffin from family guy is very amusing 😀 ordering some parts to follow your projects

They need to just bring Family Video and Blockbuster

i like the price tags they got

Wish it was in NY - what a terrific store 👍

I’d disappear for weeks

Love these surplus store visit videos. Thanks!

SLOW YOU FRIKKIN CAMERA MOVEMENT DOWN-who wants to watch stuff zipping by-I'M GONE

W O W ! ! This place is heaven on earth !!!!!!!

Hi Mike, It might be a good thing that store is far away! Big kids in big-kids toy stores. Hey - I just took apart a vintage desk-top printer. I saved the nickel-chrome plated steel shafts. Will they work for your new tumbler build?? Let me know. Great video. Thumbs up! Jim

Wow that's a pretty cool store

Wooo first comment!!!! What's up Mike

Does Radio Shack have schematics and kits to build a CB radio?

Is Fry's coming back?

So what was the reason Radio Shack left in the first place?

I love Radio Shack hope they come back

I thought we had run these junk merchants out of business. Their stores were always filled with broken returned merchandise which they would reseal and keep reselling until they found a customer who was too lazy to bring it back. They always seemed to be managed by religious nuts who somehow insured that whatever you needed to complete your project was out of stock. Please don't buy from them, it only encourages them to stay around.

I loved Radio Shack when they were stocked with DYI supplies, experiments, kits and what not. The. They turned into a phone store. SAD!

Wow, Riverton, WY. I used to go through there every once in a while. Neat they have an RS now. Re. "Not exactly a TRS-80" - RS has not sold those models for more than 30 years. I agree, it would be nice to see those come back in the sense of RS coming up with something fairly original. Though, with the way everything is now, it would likely be a Linux system running on pretty standard PC hardware. Interesting about the arrangement the store has with RS. That seems to be a trend. There's a place in my town that used to be an independent hardware store, that still carries the same name it always has, but is now "an Ace Hardware store."

The two places in my area that still pop up as radio shack one is now a home theater company and I went to that place and it was not there google didn’t update there maps. and the other is like a car stereo seller idk if there still is a RadioShack tho

... Would a WiFi Modem work?

Radidio Shuck You tell gramps you'd like a stereo for Xmas but they came out with a clock radio

the other half is missing......catalog and free battery.....still

EVERYTHING THEY EVER SOLD ALWAYS BROKE GARBAGE NO WONDER ITS HARDLY AROUND ANYMORE WASTE OF MONEY

If they sell ANY cell phones, they WILL go UNDER!!!!!! Cell phones KILLED the old Radio Shack.

they are not back

Just have to love the radio shack battery club 😀
