Like the Mac, Lisa isn't NTSC-compatible...
Of course it isn't, but...

Earlier there was the suggestion of putting the guts of a compact Mac into this gutted Lisa's case, and I do have to vaguely wonder if the Lisa monitor might be able to sync up with the output from that. I'll admit I don't know nuttin about birthin' no babies when it comes to the specifics, but based solely on a read of the specs and a look at the monitor board schematic on sunder.net it seems to me in principle you might be able to Frankenstein a compact Mac board into a Lisa. Both monitors are TTL and what specs I've been able to find indicates that they both run at 60hz and have approximately the same vertical resolution. (342 vs 364 lines. The latter figure changes to 431 with MacXL "square pixels" modification. I have no idea if the XL screen mod involved swapping out the monitor board or simply adjusting it. If it's the former then you might have less luck with an "XL-ed" Lisa 2's monitor than a plain one.)

Anyway. Someone with more monitor hacking experience might be able to shed more light on this. Granted the 512x342 on a 12" monitor you'd end up with would give your mutant hybrid a sort of Fisher-Price "My First Mac" vibe, but.. that's the best reason to do it!

I'd greatly appreciate any first-hand in-hand information on the FDD Mechanism hiding behind the Lisa's front bezel! Pictures would be REALLY COOL! :?:
The Lisa 2 was the same drive as the Mac 128k so far as I know. If you're looking for pictures of Lisa 1 "Twiggy" mechanisms a Google image search for "Apple Lisa Twiggy" will net you plenty of pictures. Here's a site with some. The drive itself isn't much to look at.

(Note the Lisa in these pictures sold for $10,000 a few years ago)
