Damn. Thanks!

He is/was a programmer and author; had a couple books on Macintosh Game programming out in the '90s, and wrote Galactic Empire, itself a port of a TRS-80 game. (Along with Galactic Trader, Desert Trek, and a few other classics.) https://www.macintoshrepository.org/3402-galactic-empire- After...

Thank you for the suggestions - I'm glad I'm not the only one, and appreciate the sanity check. I can try capturing to a ZuluSCSI - I have an external one full of CD ISOs. Most of my SD cards are 8GB SanDisk Enterprise ones, so high quality, but not nearly large enough. I have some 32GB ones I...

So, most of my vintage macs have SD or CF based storage. Generally it works, but I have noticed that sometimes it gets a little squirrel-ey. (My BlueSCSI SD cards all seem to need regular reformatting, for example.) Today, on a lark, I tried capturing a VHS cassette using the built in AV card...

This is the stuff I’m using: https://a.co/d/3Oe5oMb It’s supposedly for circuit boards, but with all the counterfeiting, who knows? Do you have any brand recommendations? I see DigiKey sells a pine rosin based flux made by MG chemicals, and they presumably don’t stock “questionable” brands.

Hi. I received the kit I ordered and am almost ready to test it, but I had a couple questions I hope someone can answer: 1) Are the "long pin" pin headers on the port board 19mm or 17mm? (I lost one. My ruler says they're 18mm on the nose, so it's off, but I don't know which way.) 2a) Any...

thanks!

I know the internal video signals of the Mac Plus and other B&W compacts are... weird. I've looked into the RGBtoHDMI, and I know that's an option, but I'd honestly kind of like a more "period appropriate" analog output. Did anybody ever design a circuit that can convert the internal signaling...

Case is in "public beta" I guess. https://www.thingiverse.com/thing:7257191/files

They have a variety of uses. I originally bought mine to find gaps and holes in my foundation where cold air was seeping in.

Resin key caps (at least using the resin I had on hand) ended up being kind of brittle, although they LOOKED great. Printing in PLA w/ ultra-high quality settings instead. It's fine, and the stems don't explode when you try to push them onto a switch. Option/Command and Delete keys were easy...

It was a pull I got on eBay. I’ve been reading and I think I can hack together a replacement chip with a Pi2040. I think. I’ll definitely post here if I figure that out, even in part - I’m not a great programmer, but if I get stuck maybe somebody else can bring it over the finish line...

I think my New Year’s resolution may be trying to reverse engineering the controller chip.

Started with a busted M0110A. Replaced the controller chip. (Socketed the replacement.) Hard wired a replacement cable. Cherry Blues plus Kailh style switch sockets and short wires. Now I just have a top case to remodel and a bunch of 3D printer work to do. It works though!

Anybody have (or know where I can get) wiring diagrams for a Mac Plus Extended keyboard? I have one that's just a doorstop; other keyboards work fine with the same Plus / cable, but this one does nothing. I'm specifically curious about how to test that big microcontroller. (Would I need, like...
