So, the only thing I hate more than people forcing me to published unfinished work because they are redoing what I spend nights already doing, is people wasting time doing what I already did…

Still needs a few tweaks but…
USB-C power adapter for the #PowerBook 5xx…
(note it doesn't provide charge)
@kalleboo @me_ What always made me wonder (not having programmed System 6/7 back in the days): There _were_ applications that handled memory allocation dynamically (e.g. some versions of Graphicconverter), and some text editors where I forgot the names, where it was _not_ necessary to adjust the memory allocation for an program in the Finder manually.
This dynamic memory API/functionality capability seemed to be added to System 7 back then. It always occured to me that RAM Doubler was a cure for programs that didn’t use newer APIs but the “old” pre System7 way of allocating memory fixed through settings in the Finder.
But, this is obsevation is deduction and guessing. Would be great to read here from someone with actual knowledge of the memory manager of System 7.
Perhaps @Cdespinosa can help or reach out?
@MrTechGadget Aaah, I tend to forget about enabling 32 Bit still after all these years. And isn’t the IIsi the machine, where you’d setup a 1 MB RAM disk, left unused, with a special driver for the IIsi, to use up the onboard RAM of 1 MB, that’s much slower due to video access, compared to the SIMM slots? What’s the name of that special RAM disk again?
New model: #PowerBook 5xx HDD caddy, with both an HDD and a #BlueSCSI variant.

Might still need some tweaks (not yet sure for screw hole diameter)
Wow, worked first try!
Just the hole for the paperclip is a bit tight. And the 2 indents need to be rotated a bit more.
I'll be recapping some #PowerBook 5xx PSUs tonight (in about 10min):

Seek to 16:55 to get proper audio, for some reason the output was muted on the soundcard

Also, there won't be an #Emulation devroom this year, but maybe your proposal can fit here
My best retro PC is my retro Mac is my Amiga. Dual boot with a twist. Some things just never get old.
@DosFox The nice part besides remote UI work with Timbuktu is that you can easily transfer files between Windows and Mac hosts with a 2pane window, without any file services setup.
"PowerBook Intelligent Battery"… hmm that was before LLMs but yeah, let's rebuild this #PowerBook 520c battery!
So now I have some things I could sell, but where do I set up online shop?
I've heard #Tindie has several problems (like, not allowing different things in the same order)… I never ordered there, any experience on that ?
#eBay is probably even worse I think…
I've seen mentions of https://www.lectronz.com/ also, any comment?
Another option is to install some WordPress + WooCommerce but I already have like 3 or 4 WP installs that are lagging on updates…
I'll be doing some #arduino tonight to finish this test gear for the battery monitor replacement for Mac LCs and others:
Edit: Had auto-start turned off it seems, so youtube missed it all.

Hey all, I ordered a set of new 512k VRAM SIMMs for my Mac LC 475. I've got one of those 10 DIP switch Mac to VGA adapters. It works fine with 512k of VRAM but once I install 1024k I can only get "Input not supported" out of my VGA compatible flat panel displays. Does anyone know how adding VRAM changes video output on the 475? Is it possible to force a 68k Mac into a video safe mode? Thanks! #retrocomputing #mac68k #macintosh #vintagemac
Logic board and PSU recapped, 68LC040 replaced with the real deal, 16 meg memory upgrade, a nice new @BlueSCSI, and a new (hopefully) quieter fan. I'd love to get a full 1024k of VRAM but those SIMMs are hard to come by. #retrocomputing #mac68k
