@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?
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)
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.
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…

New blog post! If you're setting up a BlueSCSI image for your classic Mac, there's lots of little tricks and traps for the first-timer. I'm hoping this entry will make things easier, and you'll also learn how to change your hard drive icon... in Japanese. #retrocomputing #mac68k #bluescsi

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
Welcome home! Let's get you a nice cozy heatsink and get you settled back in your case. Thanks to Amiga of Rochester for getting everything fixed up! #motorola #retrocomputing #68k #mac68k
I had to take the logic board out of my LC 475 to get it recapped. I was super careful but the plastic is so brittle I ended up breaking a couple of clips. Most importantly the one that holds the system fan. Everything is stationary but that fan is going to move around if it's loose. I was thinking about hot glueing it to the case but I'm open to other options. Thanks! #macintosh #retrocomputing #mac68k
Thanks for all the great info! I ordered a Blue SCSI and a new case fan, since the old one is pretty loud. I've got a couple of other questions:
Do you think it's worth it to spend $50-$70 to upgrade the 68LC040 to a regular 040 with an FPU? (Especially since I only spent $150 for the system.)
Do you know anyone who recaps old Macs? I'd like to get it done but my soldering skills are not "detail oriented".
Thanks! #retrocomputing #mac68k #MARCHintosh
It's alive! My Mac LC 475 is up and running! I'd like to take out the mechanical hard drive and replace it with something more modern and reliable. Is there a scsi solution that you like? #retrocomputing #MARCHintosh #mac68k
There we go, the Macintosh LC III is all set up and in a nice location to actually sit down and write some code. Got the display running at 832x624, which is spacious compared to 640x480 and doesn't look terrible on a used 19" Dell Display.
Trying out a QuokkADB to use a more modern, smaller, louder keyboard with it. So far so good.

Oh here's a question for Classic Mac dev folks -- is there a library of sample code (C for preference) for interacting with common toolbox routines out there somewhere?
Searching for stuff that dates to the mid-80s or maybe early 90s is an adventure...
The classic MacOS code segment approach is kind of fascinating. I had just sort of assumed that, being a 32bit architecture, things would be much simpler, but I'm used to 32bit platforms that lean heavily on an MMU.
The desire for position independent code (and avoiding complex relocation) combined with the 68K's limit of 16bit offsets for PC-relative access, and the need to be very frugal with memory in early Mac systems clearly drove a lot of this design.
That was an adventure. Managed to get one of the included demos to build with Consulair Mac C 5.02 on System 6 (in the Mini vMac emulator).
Setting up working search paths with the Path Manager was a bit involved. The files on the install disks were not actually organized in a way compatible with the default search path setup.
And the resource compiler refused to write a .rsrc file, but would write a .rel, which did link with some changes to the link script.
The CODE Editor for ResEdit is a neat little addon that lets you view full disassembly (instead of just a hex dump) of CODE resources, including symbol names, if present, etc.
