7 Info found at various sites:
8
9 Casio FP1000 and FP1100 are "pre-PC" personal computers, with Cassette,
10 Floppy Disk, Printer and 2 cart/expansion slots. They had 32K ROM, 64K
11 main RAM, 80x25 text display, 320x200, 640x200, 640x400 graphics display.
12 Floppy disk is 2x 5 1/4.
13
14 The FP1000 had 16K videoram and monochrome only. The monitor had a switch
15 to invert the display (swap foreground and background colours).
16
17 The FP1100 had 48K videoram and 8 colours.
18
19 Processors: Z80 @ 4MHz, uPD7801G @ 2MHz
20
21 Came with Basic built in, and you could run CP/M 2.2 from the floppy disk.
22
23 The keyboard is a separate unit. It contains a beeper.
24
25 TODO:
26 - unimplemented instruction PER triggered (can be ignored)
27 - Display can be interlaced or non-interlaced. Interlaced not emulated.
28 - Cassette Load is quite complex, using 6 pins of the sub-cpu. Not done.
29 - subcpu is supposed to be in WAIT except in horizontal blanking period.
30 WAIT is not emulated in our cpu.
31 - Keyboard not working.
32 - FDC not done.
