What was the last printed magazine article to publish detailed plans for building your own computer, and when was it? 1990s? Early ‘80s? I’m talking about plans with detailed schematics and PCB layouts, like the Mark-8 or COSMAC ELF. #VintageComputing#RetroComputing
I know this is a long shot, but do any of you have a hotsync cable for a #Palm m100 or m105? My Palm won't sync reliably and I think the cable might have a break in it.
Found a listing for a Vintage Apple IIc Personal Computer with monitor, printer, and more. It boots up! Price is currently at $302. Auction ends on May 28th. I bet this ends up getting pretty pricey, but definitely worth keeping an eye on: https://www.shopgoodwill.com/Item/199793185
Pinot is a skilled pixel artist and animator who does his work on #vintageComputing hardware, mostly early #Macintosh computers.
He suffered a devastating stroke in 2022 and lost much of his motor control. I’m glad to see him back doing #pixelArt and posting again! Give him a follow on Instagram if you’re there.
Firing up #PolyPascal on my 40 year old #Enterprise64 for the first time in probably 35 years. Actually, I'm not sure if I ever go PolyPascal running on it, or it was just the previous version, Compas Pascal. Glad to see an old #Dnaisg friend from the #CPM era again though. It's been too long.
I did discover that three clips that hold the front broke off already, need to glue them back at a later date, but the 8100 is mostly restored and quieter now as it only runs off the BlueSCSI, the HD is disconnected, but causes a slight about 10 sec delay when it cold boots.

Hate those fake updates from USPS where their computer sees that nothing has happened for a couple of days and inserts some generic "oh, we've totally put it on a truck and it's heading to you!” It has been sitting there for 3 days! Definitely not arriving today. 😔
Grouped what I think is +5V regulation on secondary side. With my extremely limited understanding, seems anode side of opto D8 is managed by HA17431 IC8. If +5V voltage falls then opto turns on and asks for more juice. Too high or just right opto is off. But how is over current handled? Could IC8 be bad and that's causing the power supply to go into over current mode?
Doing some searching about how a diode in reverse can be used as a voltage regulator leads me to Zener diodes. Looking at D22-D26, D26 has a black stripe while the rest all have green stripes. D26 must be a zener diode.
If I lift D26, will that prevent the +5V rail from coming up? Will something else on the power supply blow up without it?
Remembered I had a big variac. I was able to get the power supply to start by slowly bringing up the AC voltage. It’s hard to repeat, but I was able to do it more than once.
Sometimes those impulse purchases turn out to be pretty handy. Bought this endoscope several months ago and it has just been sitting around. Can see the labels without having to tear all the components off. #electronics#electronicsrepair#RetroComputing#VintageComputing
When I was a youngster in the late 1980s, I formed an Amiga game dev team with 2 friends.
Before making games, we started by trying to sell game music that used minimal RAM, made with our music editor SIDmon.
To promote our game music, this energetic music module was composed by our musician Ramon Braumuller. The file, including tiny sampled sounds, is only 22 kilobytes.
Our Amiga game Hoi was released worldwide on 3.5 inch diskettes in 1992.
This rhythmic tune was composed by our musician Ramon Braumuller, reflecting Hoi level 2's construction site environment. The track was made using our own music editor Digital Mugician.
