It’s neat to see the internal simplicity of a retro 8-bit computer.

I'm needing a modern replacement for an Astec ATX202-3545 power supply. I'm trying to sus out a part with it's size, but I'm concerned about purchasing the incorrect PSU. I need it to fix my Gateway tower. 
Does anyone have a recommendation of what I should get? I wish I could repair the current one (it emits a loud squeal when powered on and shuts off), but I don't have the skills to do so. :) 
New video! Trying to fix a wonky C64 board which has been worked on previously.

I have been slowly making some progress on my Amiga email client. I was able to connect to my local IMAP server and pull subject and sender info. SO much more to do but have to start somewhere.
Doom Music Playing on a Bendix G-15 Vacuum Tube Computer
"The Bendix G-15 is currently the oldest running digital computer in America, which begs the most important questions ever? Will it play Doom?"
My student, Zach, has been working to debug why our bottom tape unit has been misbehaving. We are fairly certain that the issue is a short in the interface cable between the top and bottom units, because the problem appears on whatever unit is on the end of the daisy chain. Stay tuned. But in the process of monkeying with it, there was a period of time where they both worked just fine! #dec #pdp12 #pdp #retrocomputing #vintagecomputing #umdpdp12

@stefanhoeltgen Nice.
I've recently been playing with the ACSI2STM, having purchased it perhaps oddly for mainly Spectre Mac emulation, having just added an SM124 to the setup.
I soldered an UltraSatan connector to it last night to get it on a ribbon cable with proper DB19 connector into the DMA port (was having some stability issues before).
Is this device STM32-based?
After getting home I took the keyboard apart and found a somewhat pulled-out flex cable, re-inserted it and now trackpoint buttons work on the better feeling keyboard from the 760CD, which I have now transplanted as well. Now the 760EL has the better condition keyboard and screen from the 760CD.

Great Valley Products was to the Amiga as Applied Engineering was to the Apple II.
(And, at the very end, AE started releasing some Amiga hardware, in fact.)
Probably forgetting and miscategorizing a lot of stuff but here's a PC-9801 series iceberg

In the sky above the iceberg is the most well known stuff; deep in the ocean is the most bespoke and ascended stuff.

The aNONradio NTP time standard is now installed at the SDF Computer Museum in Tukwila, WA.
Does anyone really know what time it is?
On this day in 1983, the movie Wargames premiered at the Cannes film festival. 42 years from now: https://en.wikipedia.org/wiki/WarGames #vintagecomputing #imsai8080 #wopr #hackerculture
