I think the other forums (e.g. TinkerDifferent) talk a lot about Snow – anyone else have any experiences? If you haven't heard of it, it's a faithful hardware-level emulation of early compact Macs – incl. emulated SCSI devices like a DaynaPort Ethernet adaptor + a BlueSCSI. You can simulate a...

Yes: Snow faithfully emulates a SE/30 to the extent that it can run A/UX 3.1! Of course, this is not the ideal setup, because unlike a QEMU Quadra 800 it doesn't have an out-of-the-box networking solution. Instead it emulates SCSI devices (a BlueSCSI and a DaynaPort Ethernet adapter.)...

I'm curious... do you initiate reprogramming via transferring control to hardcoded ROM code (or a simple address going down the address lines)?

Prices for Lombards and Yikes going up in 4... 3... 2...

Also, NuBus on an SE/30?

Posting in here to express my deepest appreciation for what you've done, @mihai, especially drag-and-drop file transfer! It turns out that the fastest way to move files from a Stuffit file to a Mac is to simply drag and drop into Infinite Mac, and then export a disk image. You've made my life so...

+1 to this question – seeing people do things "not the Mac way" is interesting. Perhaps a fancy bells-and-whistles debugger that didn't touch the Toolbox?

I think mini vMac might have some special traps that are used to implement "secret sauce" file import/export utility apps from within the emulated environment. (e.g. https://www.gryphel.com/c/minivmac/extras/importfl/index.html)

Oh wow, thanks for the explanation: I'd always wondered whether the "Quadra 950 ROMs" were on cards directly shucked from actual Quadra 950s to avoid having to go through Apple to license, but it looks like they genuinely distributed their own license on disk. I've always wondered as well about...

+1 for the Macintosh C Programming Primer (and Pascal, too), as well as THINK Reference. There are quite a few versions of the Reference on the Macintosh Garden, but you’ll have to hunt for the later ones.

I wonder if a SCSI-attached peripheral might be enough for your accelerator needs. At around ~600KB/s (SCSI1) it won’t be streaming a lot, though.

Yay, that’s exciting! I’ve always wanted to look for something like that to build a columns filer browser that’s more flexible than Greg’s Browsee. Did you trade off MacApp vs Carbon when you were making the decision?

Sending out prayers that there’s a cleaned up version of the source out in the aether, that doesn’t use whatever bonkers build system there is…

I actually would love to see this reverse engineered – I know that most of the Macintosh Plus' "secret sauce" logic is in PALs and a few I/O specific chips that at least have well-documented behavior (VIA, SCSI, IWM, SCSI)... the odds of having having a reverse-engineered Macintosh Plus with a...

Done, twice: once while trying to remove a stuck-in SCSI ribbon cable in a Classic; once when trying to remove a stuck-in CRT anode whatchamathingy. One of the rollercoaster moments they don't tell you about when you enter the hobby.
