First computer I touched was a #Commodore PET. First computer I owned was a Commodore 64.
#ComMAYdore
repost if your childhood started with a #Commodore computer.

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

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

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

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

#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

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

Oooh. That's a good one :) I may have to contribute to that one. I am secretly counting the days until for #ComMAYdore however.

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

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

Is #commaydore taken yet?

If not; I hereby stake our common retro themed claim, for future reference.

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

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

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

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

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...

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!

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.
