read the apollo computer inc (again, not the space craft) 1989 Design/OS principles on bitsavers!

i have no idea what the heck is going on their twitter but it looks like they're having fun

what you want more random websites that document early computational history?

no! anyway have these

@pixouls I have a project kind of similar. Well similar because it uses old machines, but none of them are computerized.

@pixouls I actually own a HP Apollo 425t. Finding a domain keyboard is near impossible though. One just sold on eBay for $250-300. The easiest apollos to find are the HP apollo 400 series. The 700 series is hppa based and is Apollo in name only, being incompatible with the Apollo domain systems.

If you want to emulate it use MAME.

Someone installing it:

@PhenomX6 wow thanks so much for sharing, this is absolutely fascinating

@pixouls Here's some photos of the later ones too.

HP 400:

More HP 400s:


There is one huge difference between the machines too. The Domains are full on ISA while the HP machines were "dual-mode" machines that featured both boot firmwares in one ROM, either ISA (for the Token Ring NIC) or HP-IB, and DIO or SGC for video. Essentially the HP machines are a hybrid of Apollo and HP architectures but they can run the last versions of Domain OS.

If you want to mess around with the OS I'd seriously consider MAME simply because Domain hardware is hard to get, and even if you find a 400/425 you will need to design your own Arduino adapter for the keyboard/mouse.

@teslas_moustache oh shit yeah i didn't know about AGC until today (my photo is not related to that) but this is truly some iconic product of DIY manufacturing

@pixouls just goes to show how bulky OLD, OLD tech was

i have a 16gb usb drive that is just a little bigger than one of the microchips

@pixouls apollo? Like in Alien: Isolation? I don't trust that megabyte!
