Took years of searching and all it required was a popular r/hardwareswap post but I got this last year. Very unique machine in my collection. It runs OpenBSD and some Linux distros (with a bit of hacking.)
Willing to go into more depth if people are interested.
I’ve got a bunch of old thinkpads, various Macs, and a good bit of 8-bit computers. Best find was a VIC-20 for $10.
