- ROM 00/01: original motherboard, 256K of RAM (banks 00/01/E0/E1 only), FPI chip manages fast/slow side
|
||||
- ROM 03: revised motherboard, 1M of RAM (banks 00/01/->0F/E0/E1), CYA chip replaces FPI
|
||||
- Expanded IIe: ROM 00/01 motherboard in a IIe case with a IIe keyboard rather than ADB
|
||||
- "Mark Twain" prototype: ROM 3 hardware, SWIM1 instead of IWM, built-in floppy, integrated High-Speed SCSI Card
|
||||
and internal SCSI HDD, 2 SIMM slots for RAM expansion instead of the proprietary memory slot of the previous IIgs.
|
||||
Only 5 slots: slots 5 and 7 are missing (5 for the SuperDrive, 7 for the SCSI).
|
||||
|
||||
Timing in terms of the 14M 14.3181818 MHz clock (1/2 of the 28.6363636 master clock):
|
||||
- 1 2.8 MHz 65816 cycle is 5 14M clocks.
