It’s almost as if this was scheduled so the seized Venezuelan oil could then be flipped to maximize profits

Happy 37th Birthday to Fujitsu's FM Towns, a computer that pushed the limits of what was possible in 1989. These are the two that I've restored - the UX Towns II in 2020, and the HG Tower in 2023, both for NEON Retrofest. πŸ’Ώ #retrogaming

PiDP-11/70 Build Workshop – INTERIM COMPUTER MUSEUM

What an absolutely amazing opportunity from @sdforg.bsky.social and the interim computer museum. If you are in or around the Seattle area, this is a extraordinary opportunity to build a PDP 11 simulator with a group of like-minded folks over two caffeinated days icm.museum/blog/?p=446

Excited to play with this. It’s a Kyroflux board intended to produce very low level backup/restores of floppy disks (platform independent). You’ll see Kyroflux images on the Internet Archive occasionally.

Here are the classic Macs I am showing at #vcfsocal this weekend. Both feature the 32-bit 68030 CPU although the Mac Classic II only has a 16-bit data bus (doh!). Both feature an internal BlueSCSI emulated hard drive #retrocomputing #macintosh #apple #Mac #bluescsi

I spent a couple of hours today at The Interim Computer Museum (icm.museum) going β€œoooooh”.

Walking into the room holding the Thinking Machines CM-2 supercomputer stopped me in my tracks. The lights are simulated right now but restoration is underway!

A man, adorned in formal white labcoat and tie stares into your eyes through coke-bottle glasses.  In his hands he holds an RCA SelectaVision Capacitance Electronic Disc.  With a deft movement he slowly releases the catch... and slowly reveals the platter inside.  You cannot resist it, you have no choice but to watch.  To look into those eyes.  To see... the future.
