Yeah, that compatibility thing's been nagging at me from about 2002 or 2003, which is a lot of years to have something on my mind.
Dr. Bob over on 'fritter said I was crazy for thinking the 2300c and the 1400 were peas in a pod. He finally came around, but convinced me that it was crazy talk to try a G3 Duo hack (back then) and now memories of those $750 prototyping adapters are beginning to translate into something that might be cobbled together to have made in a Chinese PCB Fab.
BGA pin compatibility is a given, but that's not the biggie. It's adapter translation from BGA to the QFP pads on NuBus architecture PowerBook boards that will be the brass ring. IIRC, the 5300ce board is BGA to begin with, if so, that's one dream machine for 400MHz G3 rework right there! [

Glad to hear that the technical stuff on PowerPC there is good. The MD/PhD rug rat says the science on Wikipedia is very well maintained, but I've found some of the history to be hit or miss. It's tough to take it seriously when the same-o-same-o winds up in an article because it's generally accepted, but not
quite accurate. Most of that's in military history from the first half of the last Century, but it makes me wonder about the rest.
edit: could be the 3400c that's BGA, dunno, should have been in bed a couple of houres ago . . . zzzzzzzzzzzzzzzzzzzzz
