In the OP, I was trying to get the post out quickly, so I used 603e as a generic term for early PPC. It also happens to be the Proc the PBX '030 Bus Bridge ASIC was designed to support for the NuBus Architecture PowerBooks. I've been studying that bit of Macontosh Architecture on and off for about 12 years now. I've pretty much given up on the notion of adapting a CrescendoPB-G3 to fit inside the Duo2300c . . . so I'm adapting the notion to doing a 128k/Plus using a 180c/270c LCD display with a DuoDock and two NuBus slots/cards inside.
This way I've got lots of room for adaptation of one G3 card or another to the 3200c MoBo.
As a side project, I'm going to be breaking the 1400c's PBX lines to the NuBus Chipset and adding, hopefully, three slots. This hack will be encased by the plastics of a 12" RGB Monitor.
I've tested both LCD/CRT size comptabilities and I'm really looking forward to doing some PCB work for the hacks.
What are the main differences between the 601 & 603?
