+
+Driver completely rewritten by Robbbert in a process begun on 2014-01-22.
+
+Based on the previous work done by PeT around February 2008, and possible others prior.
+ added apfm1000 cartridge loading
+ fixed apfm1000 pads
+ added apf video mode
+
+
+APF M1000/MP1000 and Imagination Machine
+----------------------------------------
+- The M1000 contains the video RAM, ROM, CPU, PIA0, handsets, Video and cart slot, and thus was a TV Game computer.
+- The MPA-10 was a base unit containing the main keyboard, custom cassette recorder, 8k RAM and PIA1.
+- When the two were joined, they formed the Imagination Machine.
+- Although the BASIC cart could be plugged into the M1000, it could not be used as it needs the main keyboard.
+- BB-01 Building Block - provides 4 cart slots. Includes a RS-232 cart for a printer or modem.
+- R8-K 8K RAM Expansion cart.
+- FI-100 Minifloppy Disk Interface Cartridge - drives 1 or 2 D100-0 floppy drives on AS-400 bus.
+- D100-0 Floppy drive 5 1/4"
+- A cassette program must be loaded on the same memory size it was saved from. Since the standard machine
+ had 8K, almost all tapes require this exact amount of RAM to be present
+- The cart-slot is physically the same as the Arcadia 2001.
+
+
+RAM switch
+----------
+- The M1000 only had available the 1K video ram (0000-03FF)
+- Space Destroyer needs more, so it includes another 1K in the cart
+- The MPA-10 base includes 8K of RAM (A000-BFFF) (-ram 8K)
+- A very few games need 16K which requires hacking the pcb (-ram 16K)
+- Basic will work with 8K or 16K.
+
+
+Status of cart-based games
+--------------------------
+backgammon - works, needs offset of 0x120, bottom line is coming from 0x3E0, should be 0x380
+baseball - works, needs offset of 0x200, some bad colours
+basic - works in apfimag only (as designed)
+blackjack - works, some bad colours
+bowling - works
+boxing - works
+brickdown - works
+columns - runs but seems to be buggy
+casino - appears to work (need instructions)
+catena - works
+hangman - works
+pinball - works
+movblock - works
+rocket patrol - works, some bad colours
+space destroyer - works
+ufo - works
+
+
+ToDo:
+-----
+- When pasting a large program, characters can be lost
+- Some bad colours or graphics
+- Tape loading is not very reliable
+- Add back the disk support when we can get some info on it
+ (6600, 6500-6503 wd179x disc controller? 6400, 6401)
+- Need to add back the disk format in the new wdc code
+ (40 tracks, 1 head, 8 sectors, 256 bytes sector length, first sector id 1)
+- Need disk-based software
