Spread the word: November 25 is #ChuckPeddleDay — celebrating the engineer behind the legendary MOS 6502 processor, the heart of so many home computers and game consoles of the 80s. 💾🕹️ If you own a machine powered by a 6502, fire it up on that day and share a photo with the hashtag #ChuckPeddleDay

Hmmm... I just saw this picture in a Craigslist ad for an IBM XT and an HP LaserJet... the original. For some reason, it never occurred to me that the line started before the HP LaserJet Series II. I've never seen an original before. #vintagecomputing #retrocomputing

This is my Total Microcomputer Model 4000 computer. Technically the last of a rare Motorola 6800 based home computer that was a pioneer in an "all-in-one" computer. Six days left on @bzotto.bsky.social Kickstarter for his book detailing Sphere Corporation here: www.kickstarter.com/projects/bzo...

After replacing an obscene amount of parts including the memory, two shorted capacitors, the LM1889 for video output and more, my Interact Model One finally works. I still get static for sound but I can live with turning the volume down for now. #vintagecomputer #retrocomputer

Dropping a surprise episode! I got the chance to interview Ben Zotto, who is publishing a book I'm very excited to read! adventofcomputing.libsyn.com/episode-1695...

As a rare Sphere owner, I just backed Go Computer Now! – The Story of Sphere Computers on @kickstarter.com www.kickstarter.com/projects/bzo... Good luck @bzotto.bsky.social !

Got my Tecmar Mac Drive working after recapping and repairing the power supply and replacing a shorted cap on the main PCB board. Very cool serial based drive that was available BEFORE Apple's HD20 hard drive solution. #Macintosh #vintagecomputer #retrocomputing

I haven't posted a decent computer pic in a while. How about this one? This is the Comterm Max PC clone in a wedge case. First available in 1984, these were used in schools in Quebec, Canada. From the makers of the Dynalogic (Bytec-Comterm) Hyperion. #vintagecomputing #retrocomputing

Playing the "Trivia Talker II" game by #Votrax on the #Commodore 64 with the "Votalker C-64" cartridge installed. I love the classic sound of the speech synthesis from the SC-01 chip within. #vintagecomputer #retrocomputer Volume UP when watching!

Working on a Tandon computer with an MFM hard drive. I didn't realize you could terminate the drive chain by plugging in a resistor pack terminator this way. I've never seen this before. Very cool. #vintagecomputer #retrocomputer

Found a Memotech keyboard for the ZX81 that doesn't appear to be used. I'm not usually a "box" person but this is a nice one. Will have to try it out the next time Sinclair is in the "review and see if everything still works" rotation. #vintagecomputer #retrcomputer

Happy 50th anniversary to the MOS 6502! Could Microchess for the KIM-1 be the first commercially available game for the 6502? The yellow booklet of the left is version 1.0. You typed it in yourself but there was an optional cassette. Let me know your thoughts. #vintagecomputer #retrocomputer

Do not miss your chance to exhibit at VCF Montreal in 2026! We’re still taking exhibitions registrations! Don’t wait too long and secure your table at #VCFMTL ! docs.google.com/forms/d/e/1F...

If you've ever dealt with a swollen laptop battery, you'll love these throw pillows on Aliexpress. When I saw these, I thought they were hilarious :)

ever wondered what it would be like to access Canada's cable TV network NABU from 1984 in 2025? wonder no mo'! some background on NABU from my book and pictures of today's explorations of the server files #othernetworks @mediaarchaeology.bsky.social loriemerson.net/2025/07/14/e...

Decapped a Microsystems International Limited (MIL) MF7115 RAM chip from 1972. This was part of the chipset of the MF7114 CPU that started out as the #Intel 4005 (4004 follow up). After Intel abandoned it, MIL continued the design work. It and this RAM vanished into obscurity after 8008 came out.

Putting together some PiSCSI units. I ordered the parts and boards and when they arrived, I quickly understood what "0402" meant in terms of surface mount components. R3 and R4 are two of them. Good Lord those are small! I lost six of them just taking the plastic off the stripe.

In my view, #Commodore died in 1994. I've got the t-shirt to prove it. #vintagecomputer #retrocomputer

Excited to see this beauty arrive. I am not particularly a "boxed vintage computer" collector but it will be interesting to explore what came with the #IBM EduQuest. I've never seen one in a box before. Unboxing will have to wait for other projects first, though. #vintagecomputer #retrocomputer

Just added to my starter pack and now it is maxed out at 150 people. That's a lot of fine retro computing folk. go.bsky.app/MG7Hn9r #retrocomputing #vintagecomputing

After many weeks of experimentation and hacking, I've finally managed to get my Ontario educational Unisys Icon computer workstation to think it's a Lexicon server and boot up it's native QNX operating system from hard drive. Now I am in dire need any software that might be out in the wild. Help!

One thing I love about #vintagecomputer collecting is reuniting obscure parts to make a more complete unit. Two items arrived today. First is the interface card for a Cyborg ISAAC for the #AppleII. Second is an #IBM Midi breakout box for the IBM PC Music Feature sound card. More to explore soon.

Microsoft ScanDisk, my old friend... Going through some old MFM hard drives and low level formatting/formatting them and ScanDisk makes a tool to exercise drives now. It used to be a great tool back in the day along with Norton Utilities and PCTools. Remember those early versions?

Never thought I’d ever have to bust out this relic from the past. I didn’t keep the BNC crimper or I would have used the crimp BNC connectors like back in the day. Need cables for a little ArcNet experiment soon. #vintagecomputer #retrocomputer

Copying files via "sneakernet" between my luggable archiving computer and the Mindset computer with working hard drive! This hard drive will have every Mindset software that existed and maybe a little more.

Just got a talking #Canon Canola SP1260D Talking calculator. I'll be opening it up in a few days to see what chipset is used. I am a collector of early speech synthesis computer add-ons and devices so this fits right in. Took a super short video so you can hear it talk. #calculator #speechsynthesis

Got an Amiga? #ComMAYdore

This is NOT a Commodore 64 with a messed up keyboard. This is a TED Developer Alpha unit (# P15) used to give early access to developers to create software for the TED line of computers including the Commodore 116, C264 and V364 and later production Commodore 16 and Commodore Plus 4. #ComMAYdore

#Commodore also produced individual chips via the MOS Technology arm. Here is a very early PONG chip used in #videogame consoles in the mid to late 70s. This is the MOS 7600-001 dated 40th week 1976 #ComMAYdore

First computer I touched was a #Commodore PET. First computer I owned was a Commodore 64. #ComMAYdore

Here's a no-often-seen Amiga 1000 add-on. This is the Amiga 1060 sidecar that attaches to the side expansion port and give the Amiga 1000 PC XT compatibility. I don't have a hard drive in it at the moment but with plenty of modern options, it would be easy to do. #ComMAYdore #vintagecomputer

As far a pioneers in the field of #Commodore products, Jim Butterfield is the first person to come to mind. Here are a sample of Jim Butterfield items including an Amiga 3000 that was Jim's daughters computer. Generous as he was, he passed onto a neighbor and I acquired. #ComMAYdore

This is why you inspect a computer and particularly, the power supply before turning on a #vintagecomputer you acquired. That RIFA cap blew out at some point and the smoke show would have continued if plugged in without inspecting first. This is from a DEC VK100 GIGI that I haven't tried yet.

I haven't seen a MUPET system on eBay in forever but it just sold for a crazy amount. I only have MUPET IIs and the one sold was a MUPET I but it was too rich for me. Here is my MUPET II that allows Commodore PETs to network and share disk drives and printers in an EDU environment. #ComMAYdore

Got this very interesting 1984ish single board computer/education trainer called "MARC". I don't know much about it and haven't even turned it on as I would love some docs on it first. @binarydinosaurs.co.uk seems to be a UK/Euro board as it's got a PAL RF modulator. Ever see anything like this?

My earliest #ComMAYdore PET 2001 is one of the first 100 (serial 10051) and it's actually a pre-production model that Commodore eventually sold. Various differences include no motherboard solder mask and instead of the top holding kickstand is a "scissor" support that was replaced in production.

There's still lots of "CBM" Time to post your own Commodore #ComMAYdore items this month! Don't forget to use the hashtag #ComMAYdore. #vintagecomputer #retrocomputer

Well, I made my first 4 layer board reproduction in KiCad and I have no idea if it will pass the review stage at the PCB maker. Took a lifetime to figure out how to do cutouts. It's a SASI hard disk cartridge for the Mindset computer. Yes, it had a hard drive. #vintagecomputer #retrocomputer

Some people may know that #Commodore used to sell calculators. Shown here is the Commodore 512 calculator which was a simple 4 function calculator but those nixie tubes make it special. This is a rebranded Casio model. I had to refurbish the wood look metal plate with real teak veneer. #ComMAYdore

A very good friend of mine made this #ComMAYdore even better this year. Knowing I like Speech Synthesis on various computers and devices, he sent me a Votrax Voltalker C-64 cartridge w/ SC-01-A. This is awesome just to hold. I'll have to clear off some space to archive the disks and try it soon!

I am not sure if this is only in Canada as I have a mix of Commodore 64s but with the boxes lined up, you can see how the boxes changed. Very early C64 boxes had a 4040 style dual disk drive on the box. Later ones had the 1541 disk drive on the box when they were available, I guess. #ComMAYdore

For #ComMAYdore I must post one of the jewels of my collection. The Commodore 65. For #Commodore fans, nothing more needs to be said. #vintagecomputer #retrocomputer

Commodore used to advertise that the C64 could run the CP/M operating system. They had a cartridge for it that probably most people have never seen (unless you are a CP/M fan like me). Here is the full set up running CP/M from Digital Research. #ComMAYdore #vintagecomputer #retrocomputer

Did you know #ComMAYdore made a cash register (CCR)? It was only available in a trial market. I saw one on Craigslist but it was too rich for me. I did manage to buy a blank Universal CMOSRAM PET board and the Magic Board that make up the main circuitry. I also know who bought the working CCR...

In contrast to the #Commodore Educator 64, a Commodore 64 in a PET case, this metal enclosure was an alternate solution used in the Canadian education market so that C64's wouldn't "walk away" in a lab environment. It locked a C64 in place with room for a 1702 monitor on top. #ComMaydore

I've got a collection of a hard to find #Commodore PET called the "Educator 64". This was a case of all being non-working until I fixed one and then could fix the rest. It's basically a C64 in a PET case mainly used in education. Unlike the "PET 64", this has sound and "greenscale". #ComMAYdore

The #Commodore ChessMate was a customized version of the MOS KIM-1 with Micro Chess by Peter Jennings. From 1978, it was a stand-alone electronic chess playing device. The yellow booklet is the first Micro Chess for the KIM-1 that you typed into your KIM-1. Software cassette optional. #ComMAYdore

OMG, I totally forgot it was #CommMAYdore time! I'll need to post some #Commodore computers and stuff this month. Please post some #CBM goodness if you have any. For my first post, this is a Japanese Commodore Max Machine, only available in Japan. #vintagecomputer #retrocomputer

I've been on a bit of a Roland kick lately to get some PC cards and devices used for vintage gaming. I came across the Roland MT90s and just had to get it to play some MIDI (GM2) tunes. Here it is after I installed a Gotek in it as this model normally uses a 3.5" floppy drive.

Haven't posted because a terminal repair is kicking my butt. My last post was a piece of Commodore history in the early office furniture catalog. That said, do you know what the earliest Commodore logo was? It's on this early typewriter, sitting on a Commodore typewriter stand.
