AFAIK, real Pluses can run System 7.0.x (prolly 7.1.x also). So a GCR with Plus ROMs (maybe even with SE+FDHD ROMs) should be able to run System 7. Any real limitation would be on the ST side where storage concerns begin to pop up.

Hmmm... I've considered trying other ROMS but I have been hesitant for obvious reasons. But then again, like you say, the Macintosh Plus can run up to 7.5, so I don't understand where the problem was.
Dave Small said he spent many nights trying to chase down why it wouldn't work. I think he was experiencing the financial troubles at Small,Inc by that time unfortunately.
Other mentioned it was the way System 7 accesses the DSP? The initial program did not access it the same way. Something like that.
But hey, I hope that one day we will get bored and find a way to make it happen.

I know a friend of mine used to program on the ST and even came up with a resource fork parser that would check a resource forked file and extract the ICON (1-bit 32x32 icons w/ mask), icl8 (8-bit 32x32 icons, using the ICON mask), and other assorted useful Mac resource types. Back then, we were both in awe of the vast information resource that was Inside Macintosh.

Oh yeh, a lot out there. Makes one appreciate the trouble Dave and company had to go through to make this happen.
