Stuttgart Computer Museum - demonstration of an Intellec 8 (with PDP8e and ASR33)

[Jon Hales]

A friend in a European country told me about this recent video (dated 8 May 2025).

The video runs for just over one hour. The commentary is in German. I have converted the 'Transcript' to English via Google Translate (which is not entirely accurate).

The Intellec 8/MOD80 is shown in operation on the display of an HP terminal connected to the PDP8e. The video includes (with a few false starts):

- compiling a test program in PLM (possibly with a cross-compiler on the PDP8e)

- discussion of Intel hex and BPNF

- writing a set of monitor EPROMs (1702As) for the Intellec 4/MOD40 (some mishandling of PCBs)

- a glimpse of a Tiny BASIC.

The link to the YouTube video is: https://www.youtube.com/watch?v=pdhJmxakL0I

I've attached a transcript (PDF - 20 sides). If the 'Transcript' option is selected in YouTube, the timestamps make it easy to keep track of the position in the printed copy in English.

The museum has a considerable number of previous videos on YouTube.

Best regards

Jon

The folks at that museum are amazing!

I have an EVK-100 PCB, a very rare 6800 system from AMI. The 100 was a bare PCB and the 300 was a complete system. No docs... Found out that the museum had one but they had no docs, however, they offered up a bunch of high-res photos so I could read the parts and build mine. I ended up tracking down docs for it through a guy in Arizona who sent his to England where another person was going to scan them. I got a copy, gave it to the museum and they not only powered theirs up, but they dumped all the ROMs and sent me code files for it. :) 

I put all of it up on the Internet Archive so it wouldn't get lost to time... and in the meantime, I found a completed EVK-300 system from a gold scrapper in New Zealand who shipped it to me for some PayPal lovin'. :) 

Not 100% on topic, but hey, those museum folks in Stuttgart are awesome in my book.

did you upload those to the IA as well?
