I just completed a full restore of a PB190cs, only to realize that, apparently, it's the ONLY(?) 68k machine that doesn't support system 7.1. Or is there a way to make it work? I checked the System Enabler docs but I don't see a supported version.
I was referring to any variant of 7.1 (including 7.1.2 etc). But yeah, looks like Performa 630, 640, and PB190 are the only ones without either native 7.1 support or a system enabler. I guess Apple just didn’t bother for these three models. Weird.
I assume the way it works is that the System checks the machine ID during boot and will refuse to start if the machine isn’t whitelisted? Are there any workarounds?
Yeah, I was afraid of that. Although I was still hoping that someone found a way...For it to actually boot you'd have to make a custom enabler for it, containing drivers for chipsets and similar. In practice you'd probably start with something like the PB 500 Series enabler and modify it.
What's your motivation to run System 7.1 on the 190?
Sound advice right there.Yes, install a minimal 7.5, open it in resedit and run amuck with the delete key. It'll be fun and educational ;-).
You can trash the Sound Manager 3.x extension on pre-PPC machines. Super Tetris works fine on both my IIfx and Quadra 650, running 7.5 and 7.6.1, respectively. If the Sound Manager extension is installed, the game is silent.
I've even run Arkanoid on a LC 475 under 7.5.5. Again, works just like it does on a Plus, running System 6. Just a lot more responsive.
I'd run System 7.5 on any 68030 Mac faster than 16MHz, so a IIsi or up!
Meanwhile, System 7.5 can be squeezed into 3900kB on a PowerMac 6100 in 1bpp mode.

Or down to 2500kB on a Q650, both via Infinite Mac. Gosh, PPC is hungry!
