Just a CC newbie wanting to say "hello"! ☺ Thank you, Stuart Bell, for pointing me over here, and for graciously answering all my questions up to this point.
By way of introduction, I'm a web software developer and have been using Macs for 15 years. I've bought three new as desktop systems, and many many more have passed through my possession also. As a hobby, I run various Unices on most of my older Macs. I build binary software packages for NetBSD/mac68k users, and lend some processing power to OSS projects that target 68k.
I have a beautiful CC and a 575 mobo just dying to get inside. My question (for clarification) is this: if I do the ResEdit/Enabler hack for my Mystic now, I need to "undo" it when I make the VGA mod later - correct? Other than editing the System or Enabler file, is the "Mystifying" process really as easy as sliding out the old mobo and sliding the 575 in? That seems too simple. But I won't complain! After I do the ResEdit hack, will the CC still boot with the original mobo? If not, what if the 575 mobo died while I had it in storage...I'd be just stuck? ☹ I have no way to test it.
OK, that was several questions. Hope you don't mind. ☺
Anyway, I'm really looking forward to having a working Mystic. I plan to run NetBSD on it, to have a cute little color X terminal. It will make a very nice demonstration piece, and with a big enough disk, a good second "build box" for those software packages.
System 7.6.1 installed, System file hacked, Mystic upgrade complete! Woo hoo! As soon as I get the full '040 transplanted, I'll be ready to install NetBSD.
Full '040 transplanted without difficulty. After resetting the machine ID in the NetBSD booter app from 99 to 92, it booted up nicely. It's currently running 2.1 and I'm installing a couple GUI packages just to see how they look on the small screen.
