@thisdoesnotcomp @ActionRetro Reminds me that I sadly declined getting an #IBM #PC300GL Pizzabox with the low-profile #PizzaboxCase and relatively rare #MicroATX #Mainboard compatibility, cuz that one would make a good "#SleeperPC" / #Retro #BridgeMachine...

Just to be clear:

The #tiny486 is intended as a #devkit for #i486 (in theory even #i386, #i8086 or any other platform that does #ISA (& #PCI) or where one's willing to accept less functionality of a #PC104 compared to #PC104Plus.

As a #BareMetal reference platform for #OS1337 / @OS1337 because there is a demand for a "#BridgeMachine" with new parts even if it's just to do #Archival and #DataRecovery duties and help setup modern drop-in replacements.

  • I'd not be surprised if @TechTangents got contacted by some agencies that still have to deal with 8" FDDs and has to basically deny it.

Given that I want to target i486 with @OS1337 but don't want to deal with obsolete hardware that is dying of old age, I think it's more fitting to consider a sort-of mainboard to shove some 486SX-SOM with PC/104-Plus on and have the few necessities hooked up to it. Maybe even put it inside a THINN #Pizzabox-style #case?

It would also make a new "bridge" machine to interface old PCI & ISA hardware and allow connecting i.e. a #QuadFlop and roll with that...

TBH, I wished I had an Epson SD-800 (which is a 5,25" 720kB + 3,5" 1440kB combo in 1x5,25" half-heigt bay) or even better a 1200kB 5,25" and a 2880kB 3,5" drive, but I only have one computer with a floppy controller.

Cuz that and a #LightScribe DVD Burner would make for a good #BridgeMachine out of a #Z600...
