PMD-85 driver by Krzysztof Strzecha

What's new:
-----------

27.06.2004  Mato crash fixed.
21.05.2004  V.24 / Tape switch added. V.24 is not emulated.
25.04.2004  PMD-85.1 tape emulation with support for .pmd format files added.
19.04.2004  Verified PMD-85.1 and PMD-85.2 monitor roms and replaced with
        unmodified ones.
        Memory system cleanups.
03.04.2004  PMD-85.3 and Mato (PMD-85.2 clone) drivers.
        Preliminary and not working tape support.
        Reset key fixed. PMD-85.1 fixed.
15.03.2004  Added drivers for: PMD-85.2, PMD-85.2A, PMD-85.2B and Didaktik
        Alfa (PMD-85.1 clone). Keyboard finished. Natural keyboard added.
        Memory system rewritten. I/O system rewritten. Support for Basic
        ROM module added. Video emulation rewritten.
30.11.2002  Memory mapping improved.
06.07.2002  Preliminary driver.

Notes on emulation status and to do list:
-----------------------------------------

1.  V.24.
2.  Flash video attribute.
3.  External interfaces connectors (K2-K5).
4.  C2717PMD is marked MNW, but there's nothing to say why.
5.  Verify PMD-85.2A, PMD-85.3, Didaktik Alfa and Mato monitor roms.
6.  Verify all Basic roms.
7.  8251 in Didaktik Alfa.
8.  Colors (if any). Seems most versions supported 4 colours via RGB connector. But, the TV modulator only carried the G line.
    The video signals are developed in a forest of gates which may take a while to work out.
9.  PMD-85, Didaktik Alfa 2 and Didaktik Beta (ROMs and documentation needed).
10. FDD interface (ROMs and disk images needed).
11. "Duch & Pampuch" Mato game displays scores with incorrect characters.

I/O ports
---------

    I/O board
    ---------
    1xxx11aa    external interfaces connector (K2)

    0xxx11aa    I/O board interfaces
        000111aa    8251 (casette recorder, V24)
        010011aa    8255 (GPIO/0, GPIO/1)
        010111aa    8253
        011111aa    8255 (IMS-2)
    I/O board is not supported by Mato.

    Motherboard
    -----------
    1xxx01aa    8255 (keyboard, speaker, LEDs)
            PMD-85.3 memory banking
            Mato cassette recorder

    ROM Module
    ----------
    1xxx10aa    8255 (ROM reading)
    ROM module is not supported by Didaktik Alfa and Mato.


Commands
--------
DUMP aaaa - dump memory from aaaa
JUMP aaaa - start program at aaaa
MEM aaaa  - show 16 bytes from aaaa-up
MGLD xx   - load file number xx from cassette
MGSV xx aaaa bbbb yyyyyyyy - save memory range aaaa to bbbb to cassette with file number xx and filename yyyyyyyy
MGEND - ?
SUB aaaa bb cc dd... - write bytes to memory starting at aaaa with bb,cc,dd...


Cassette
--------

Cassettes tested with Basic
- pmd852,pmd852a,pmd852b,pmd853,c2717,c2717pmd - these can save and load back their own files
- pmd851,mato,alfa - not tested yet.

Getting into Basic:
- pmd852,pmd852a,pmd852b,pmd853 : In the Machine Configuration, enable Basic and Reset.
- pmd851,alfa : type BASIC 00 (or any parameter)
- mato : type BASIC
- c2717,c2717pmd : you're already in Basic.
- How to get out? Unknown.

Loading a tape:
- In the monitor : type MGLD <fn>, where <fn> is the file number, usually 00. File numbers will be shown in the
  software list usage.
- In Basic : type LOAD <fn>, where <fn> is the same as above.
- The tape can only be loaded into the environment it's meant for. Otherwise, you'll only get header information
  followed by a freeze.

Header information from what I can understand: xx/z yyyyyyyy
yyyyyyyy = filename
xx = file number
z = status code (guesses below)
    > - only loadable by Basic
    ? - only loadable by the monitor - it gives no clue as to the exec address, but should start by itself if it's
        been saved correctly.
    x - other codes are added by the user and have program-specific meanings.

Software list items: Some work, some don't, and some only work on certain machines. A test with "bludiste"
(a monitor program) produced the following:
- pmd851,pmd852,pmd852a,pmd852b,alfa - loads and runs
- c2717,c2717pmd - recognises and prints the header, but then doesn't load the tape, because the machine is
  stuck in Basic.
- mato,pmd853 - does nothing

Some software items will crash MAME, for example "bdash".
