I’m a terrible 8-bit vintage Tandy/Radio Shack and vintage Apple collector. Professional software engineer for far too long.

Making your own computer chips in your garage - it takes a lot of really old-school photographic work, with the addition of a whole bunch of heat.

Microsoft BASIC for the Motorola 6809-based Dragon 32 was recently discovered... in an attic, printed out on 340 pages of fan-fold paper, now carefully scanned and OCR'd for posterity.

Hunger (1974), one of the first computer-completed animations: humans drew the keyframes, while a custom assembly-language tweener running on the SEL840A linked them.

From 4K graphics down to only 4k of memory, Halo 2600 boils the Halo series down to it minimum and keeps cutting.

The Burroughs/Unisys ICON was an educational computer in Ontario, Canada and almost none exist. I do have one of the earlier models but ICONs were client computers that ran off of a LexICON central server. I need to try to resurrect that, if possible.

When Tandy cancelled the OS-9 line, fans in 1990 tried to step up. The MM/1 beat the Amiga, Mac, and most PCs on price, but with less than 500 units made - and only 8 ever sold, not including the giveaway mentioned in this ad - there was never going to be the software needed. (Source.)

This is the story about how the biggest CRT TV ever made was preserved and saved from destruction. A truly epic story for an absolutely epic product made by Sony during their glory years.

Getting emulation to work often takes deep dives into hardware - not just the intent, or the documentation, but the actual examination of sometimes rare and irreplacable chips. CocoTown describes this technique in DragonFire, a game for the TRS-80 that rode at the very limits of the system.
