Usagi Electric, Forgotten Machines, & Nevets at VCF Southwest 2025
[Usagi Electric], [Forgotten Machines], and [Nevets01] collaborated on a massive exhibit of unique old hardware.
[Usagi Electric] had an interactive exhibit with his recently rebuilt PDP 11/73 running examples of spectroscopy analysis using a Bomem vector processor. [Usagi] also demonstrated a Data General Nova 1210 running BASIC.

[Forgotten Machines] had a variety of old terminals, computers, and peripherals on display. He was on-hand throughout the show to help anyone image and preserve their old magnetic media.

[Nevets] had an interactive exhibit with a Data General Nova 1200 running BASIC alongside a (sadly non-functional) Digital Computer Controls D-116, a clone of the Nova 1200.

I found the culprit behind the spurious /INTR signal from the Cassette I/O board that's been holding up the Nova 1200 Logic Test from completing successfully.
Tumblr media
This 7474 is ancient, and has no pull-up resistor on the /PRESET input (which is fine for the original variants, though not recommended). The Q and /Q outputs (cyan and magenta) should be mirror images of one another, and they are not.
Tumblr media
So I replaced it with a new 74LS74 part, which meant I had to add in that /PRESET pull-up resistor:
Tumblr media
Testing the old 7474 confirms it's a piece of shit:
Tumblr media
I ran the Nova 1200 Logic Test and... it passes. Repeatedly! Address 00121 contains the number of successful passes, which is over 8000!

Okay, let's go for broke: loading up Data General Single User BASIC...
Tumblr media
HOLY SHIT IT WORKS!
Only took like 3 years to get it back to an operational state, but there it is, running BASIC again.
