S100 bus computers new and old - Jay Cotton
VCF West XVIII
Lights & Switches at VCF Southwest 2025
Front panel computers were well represented at VCFSW this year.
There was this mini S-100 system featuring the [Don Caprio] IMSAI front panel replica and a reproduction Cromemco Dazzler video card.
This miniature PiDP-11/70 got to sit on display next to its full-size PDP-11/05 brethren (which was itself featuring a UniBone peripheral emulator).
This SCELBI-8B reproduction was waiting for anyone to try their hand at bootstrapping a computer using just a handful of switches.
Blinking lights of the Altair 8800 could be found all across the show floor in the form of an 8800 Mini, a proper vintage 8800b, an 8800a clone running on a Raspberry Pi, and an 8800 Clone.
There was also this beautiful HP 5036A Microprocessor Lab, an 8085A CPU trainer that had nothing to hide.
In all, it was a great year for toggling switches and watching blinkenlights!
Sandhill's running real nicely in this Brookhaven Instruments chassis. I've been working on some new boards now that I have 22 slots available: A 8086 processor board, a 80486 board, and a MS-DOS support board that implements all the usual peripherals IBM PC software expects a system to have.
Look at my girls
The coolest thing I saw at the local vintage computer meetup: a rare example of an unreleased MITS sound card for S-100 machines, probably the earliest such sound card ever made. MITS was the company that created the Altair 8800 (and later 680), and effectively created the ad hoc S-100 standard. It's got 6 level polyphony which is pretty cool for something made mostly with general purpose chips. The only thing special is that one chip with the heat sink for generating the master octave from which everything else is derived.
