You assume incorrectly. The early Macs' video signal is designed for its analog board and nothing else. The closest analogue (pun unintended) to something contemporary with the Mac-- remember that VGA wasn't invented until 1987-- is the 350-line mode of EGA... and even EGA wasn't invented until...

Neither SimCity 2000 nor Prince of Persia use QuickTime for music playback. Both of those games (as well as a number of others, such as SimAnt, Lemmings, Wolfenstein 3D,...) license the SoundMusicSys engine from Halestorm, which only generates software-synthesized sounds through the Mac's...

I do know that the Sound Driver implementation in Mini vMac is buggy / incomplete-- Lode Runner running in AMS for example more accurately reproduces what a real Mac sounds like, whereas in Mini vMac some sounds are incorrect.

Of course it modifies the VBLQueue directly-- it would be a dead giveaway seeing a call to _VInstall. ;)  You thought they'd make this easy?  :p

MacsBug doesn't live in the system heap. It lives in high memory above (BufPtr). The address stored at location $120 in low memory (if not null) points to where a debugger is installed. I would check to make sure there isn't a VBL task installed somewhere. I'm reverse engineering a...

3.5" floppies? If they're not copy-protected, then Disk Copy 4.2 on the Mac should image them just fine. Extracting the data from them is another matter, but emulators such as LisaEm exist that might help there.

None off the top of my head that don't require emulation. The Classic's lack of a MMU is a significant limiting factor.

Is there a particular reason why you don't want to use the patched HD SC Setup utility? I'm just curious.

For folks in the Bay Area, I was at WeirdStuff Warehouse this past Sunday and near the entrance of the store, on a shelf they had four new-in-opened-box Miracle MT209A 9" monochrome SVGA CRTs for sale. $50 each. I picked one up for myself but they might still have some left, if you're interested...

It's also possible that the connection from the speaker itself to the logic board might be faulty. My dad had a IIsi with an oxidized speaker connection-- this is a common problem with that model. If a sharp rap to the top of the case will occasionally restore sound, that might be the issue.

I picked up a 23" Cinema HD they had when I visited there this past Saturday. All those Power Macs, ImageWriters, and the Personal LW were still there. The towers are missing bezels, as BMOW's photo shows.

Ambrosia got the themes for Escape Velocity (Face of the Enemy) and EV Override (Larry's Orchestral Adventure) from Killer Tracks. Since EV was released a year after Apeiron, it's possible they had a relationship with KT by then, so I would start looking there. :)

HD68.

I traced the pinout of my GM ROM today just to confirm some of the conjecture in this thread, and raise a couple more questions: https://pastebin.com/nzxFhpXg - Pins 1-2 of the ROM socket indeed are wired to Vpp on all of the GM Flash chips. - /WE is not only present on the GM edge, but it's...
