fixed apfm1000 pads
|

added apf video mode
|

|

todo for apf m1000:
|
||||
add exact cpu/video timing. memory controller+6847 memory operations hold cpu
|

(backgammon relies on exact video timing)
|

support special cartridges (basic, space destroyer)

0000- 2000-2003 PIA of M1000. is itself repeated until 3fff.
|
||||
She controls " keypads ", the way of video and the loudspeaker. Putting to 0 one of the 4 least
|
||||
significant bits of 2002, the corresponding line of keys is ***reflxed mng in 2000 (32 keys altogether).
|
||||
The other four bits of 2002 control the video way. Bit 0 of 2003 controls the interruptions. Bit 3 of 2003 controls
|
||||
the loudspeaker. 4000-47ff ROM of M1000. is repeated until 5fff and in e000-ffff. 6000-6003 PIA of the APF.
|
||||
is itself repeated until 63ff. She controls the keyboard of the APF and the cassette. The value of the
|
||||
number that represents the three bits less significant of 6002 they determine the line of eight
|
||||
keys that it is ***reflxed mng in 6000. Bit 4 of 6002 controls the motor of the cassette. Bit 5 of
|
||||
6002 activates or deactivates the recording. Bit 5 of 6002 indicates the level of recording in
|
||||
the cassette. 6400-64ff would be the interface Here series, optional. 6500-66ff would be the
|
||||
disk controller Here, optional. 6800-77ff ROM (" cartridge ") 7800-7fff Probably ROM. The BASIC
|
||||
leaves frees this zone. 8000-9fff ROM (" cartridge ") A000-BFFF ram (8 Kb) C000-DFFF ram
|
||||
additional (8 Kb) E000-FFFF ROM of M1000 (to see 4000-47FF) The interruption activates with
|
||||
the vertical synchronism of the video. routine that it executes is in the ROM of M1000
|
||||
and puts the video in way text during a short interval, so that the first line is seen of
|
||||
text screen in the superior part of the graphical screen.

APF M1000/MP1000 and Imagination Machine
|
||||
----------------------------------------
|
||||
- The M1000 contains the 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 and PIA1.
|
||||
- When the two were joined, they formed the Imagination Machine.
