/***************************************************************************
Driver completely rewritten by Robbbert, in a process begun on 2009-02-24.
Assistance/advice was gratefully received from:
E.J.Wordsworth (owner of Microbee Systems), nama, ChickenMan,
and the author of the "ubee512" emulator.
Previous driver was written by Juergen Buchmueller, Jan 2000 with assistance
from Brett Selwood and Andrew Davies.
Keyboard notes are in video/microbee.cpp
256tc: The 1.31 rom version which appears to fit the 256TC is actually
part of the Z80 emulation in the Matilda model. If you fit this rom into a real
256TC, the floppy disk will not be detected.
The unemulated Matilda is a IBM XT clone fitted with a NEC V40, and has the
ability to emulate the 256TC as mentioned above.
The Premium Plus was a limited-edition kit from Microbee Systems, but we don't
have any technical info or schematic as yet. It starts up, keyboard works, disks
work much the same as a 128k or 256tc. It has 1024k of RAM.
The kit itself has an extra custom FPGA CPU board with memory-card slot, but there's
no info on it yet. We just emulate the Z80 portion.
ICs on schematics, pcbs, and manuals which never made it into production machines:
- Z80SCC;
- SN76489A;
- 2651A;
- B & C roms on disk-based machines.
Floppy formats:
- All disks are the standard CPCEMU 'dsk' format.
- Types are 9/13cm 40/80 track (single or double sided)
- 13cm has been specified as QD to prevent a nasty crash if an 80-track disk was mounted
- The tracks/sector layout is the same regardless of size
- Although certain models came with particular drives as standard, users could add
the other size if they wished. We support both sizes on any model.
Early machines have 'standard' video (128 hires characters).
Later machines had the option of 'premium' video which
provides thousands of hires characters, enough to simulate
bit-mapped graphics.
Commands to call up built-in roms (depends on the model):
NET - Jump to E000, usually the Telcom communications program.
This rom can be replaced with the Dreamdisk Chip-8 rom.
Note that Telcom 3.21 is 8k, it uses a rombank switch
(by reading port 0A) to swap between the two halves.
See Telcom notes below.
MEM - same as NET.
EDASM - Jump to C000, usually the Editor/Assembler package.
MENU - Do a rombank switch to bank 5 and jump to C000 to start the Shell
PAK n - Do a rombank switch (write to port 0A) to bank "n" and jump to C000.
These early colour computers have a PROM to create the foreground palette.
Notes about the printer:
- Older models default to a 1200 baud serial printer, which we do not support.
- You need to change it to parallel by entering OUTL#1 while in Basic.
- After you mount/create a printfile, you can LPRINT and LLIST in Basic,
or by using the printing option in other apps.
Notes about Telcom:
- On the older models, Telcom is called up by entering NET from within Basic. Models
from the pc85 onwards have it as a menu option.
- To exit, press Enter without any input. Disk versions, enter CPM or press ^C.
- After being used, version 3 and up will enable the use of OUT#7 in Basic, which
changes the screen to 80x24. Enter OUT#0 to revert to normal.
- Most versions of Telcom can have their parameters adjusted directly from Basic,
without needing to enter the Telcom program.
- Most versions of Telcom have an optional clock. In older models firstly select VS
from the MAME config menu, then enter NET CLOCK to enable it. NET TIME hhmm to set
the time (24hour format). NET CLOCKD is supposed to remove the status line, but it
doesn't, although the clock stops updating. NET CLOCK and NET CLOCKD are toggles.
- Telcom 1.2 (used in mbeeic) has a bug. If you enter NET CLOCK, the status line is
filled with inverse K. You can fix this from Basic by doing NET CLOCK 3 times.
Notes about Disk System
- Ports 44 to 47 are for standard connection to FD2793.
- Port 48 is used for drive/side/density select on write, and intrq/drq on read.
intrq and drq are OR'd together, then gated to bit 7 of the data bus whenever
port 48 is activated on read. There are no interrupts used.
- The 256TC can boot from the B drive if you hold down Shift and hit F1 at the menu.
How to use the config switch for PIO B7:
- Teleterm: Must use RTC. Anything else makes teleterm go crazy.
- 256TC, 128, 128p: Doesn't seem to matter, leave at the default.
- Standard: Has no effect, best left at "Tied High"
- Other rom-based models: "VS" to make the Telcom clock work, or "Tied high".
- 56k: not sure yet, leave as "Tied high" until more is known.
***************************************************************************
TODO/not working:
Old CRTC-based keyboard:
- Paste drops many characters.
- Typing can drop the occasional character.
- mbee -bios 1 is unusable due to keyboard issues.
FDC: (TODO: see if these bugs still exist)
- B drive doesn't work with most disks.
- some disks cause MAME to freeze.
- 128k: Simply Write has no keyboard.
- 256tc: the Intro disk doesn't work
- 256tc, Teleterm: Keyboard CPU inbuilt ROM needs to be dumped.
- 128k, 64k: PALs need to be dumped for the bankswitching.
- Mouse: a few programs support the use of a serial mouse which interfaced
directly to the Z80PIO. However there's little info to be found.
PIO B3 to ground activates the mouse pointer in Shell v3.01.
- Hard drive (10MB) & controller
