In brief/off topic, chipset components in the 5300 are more related to the 190 overall, they're considered one generation in the '040 to PPC transition era. The 2300 and 1400 are nigh on identical, being the next gen offerings along with the 3400c as the high end of the lineup, featuring migration to the PCI/PC-Card architecture.
The largest difference between 2300 and 1400 was provision for moving the TREX PCMCIA controller to a docked upgrade. The ECSC Video Controller capable of driving the 800x600 LCDs of the 5300ce and 1400 was dumbed back down to to the pin compatible, but 640x480 limited CSC of the 190 in the RoadApple hobbling tradition for the low end offering.
Apple hated the very notion of providing a PPC upgrade path for the Duo line, they wanted migration limited to sales of full PPC 'Books. Avoiding a class action suit by three generations of Duo owners promised a PPC upgrade path was the only reason for the 2300c to have been developed at all. Gotta love its versatility, especially the SCSI/IDE controller combo for the internal HDD.
NuBus architecture PPC PowerBooks are my thing. The Mustang Prototype, a 5300 with the 11.3" LCD of the 1400 shoehorned into the lid of a 5300 is my Eleanor.
Dunno where it fits in on the development timeline though, 5300 is a sideline interest. I've been hacking at the margins separating the 2300 and 1400 for at least 12 years, since the heyday 'fritter in the Dr. Bob/Eudimorphodon(Gorgonops) era.
