Rockwell AIM-65 6502 Vintage Computer: Display Board, Speech Synthesizer, Basic, and Forth

I explore the Rockwell AIM-65 vintage computer. This is a 6502-based computer from the late 1970s. This computer came with 4KB of RAM and 20KB of ROM, and had some kind of calculation program installed for what I think is a manufacturing company. It came in a nice all-metal industrial case. I build a display board that uses the 6545 CRTC chip to render composite video. I also build a speech synthesizer using the SP0256A-AL2 speech synthesis IC. I also demonstrate using BASIC and Forth languages, and establish a serial connection to the vintage computer. For more vintage computer videos, see www.smbaker.com/

Great video, I learnt 6502 machine code/assembly on one of these versatile robust machines back in 1981. I retrieved my AIM65 from storage to have play and have started to recreate your Display card which really makes the machine more usable.

I love that alphanumeric LED display.

Cool. The AIM-65 was my second computer back in the day. I first got a KIM-1 in 77, then the AIM and finally an Apple ][ some years later. After that it was an IBM XT and the "exciting magic" feeling of computers went away and it all became a bit more boring.

Oh man, I’d do anything to get to mess around in forth on that thing! Amazing stuff ❤

Oh yeah, thinking of which - I still need a speech synth for my Microprofessor 😊 nice video, thanks for sharing. We certainly share a common Obsession when it comes to vintage speech synths 😂

Just a few years ago, I pulled one out of a public dumpster. I couldn't believe my eyes! And it works! It's got BASIC installed and there is a huge circuit board in its "basement" with 36k of RAM (18k battery backed 6116 and 18k non-battery backed 2114 and yes I know 18k is a weird number) as well as a few ROM chips. It didn't come with the cable that connects it to the AIM-65 though and I haven't dumped any of the ROMs yet or tested the RAM, I just removed the VARTA Destroyer Of Boards (TM) battery. (first thin I did was take it to a retrocomputing expo and wrote a small BASIC program that would scroll "LEGALIZE DUMPSTER DIVING" across its gorgeous bubble LED display - as in Germany, I'm pretty much a criminal stealing antique computers out of dumpsters)

Thank you for a marvelous trip!

[@alexgayer85]

What a cool machine

[@The.Doctor.Venkman]

I first saw this at college when I was 17 years old (1982) It was used to teach us 6502 machine code programming. This is so nostalgic - Thank you!

There’s your like and fallow good man

[@miked4377]

that computer is so nice....I love rare hardware..I have never seen this model....very nice.what year 78 79?

[@miked4377]

ok 79 then..

[@snarfusmaximus]

Great video, as always. I have a soft spot for 8-bit development systems and an AIM-65 is one I've always lusted after - like a KIM-1 on steroids. I do have a KIM-1 though so I really can't complain.

[@esra_erimez]

These machines were long before my time, but I love these videos.

[@alpcns]

Brilliant stuff! Great video, thank you for sharing!

[@netdudeuk]

Thanks Scott. Always love your videos. What do you use to compile for your 22V10s ? Thanks.

[@RaquelFoster]

It would make more sense if the Rockwell AIM-65 was some kind of anti-interceptor missile developed for the Rockwell B-1. Maybe if you type in the right numbers it can 3D print you one?
