/***************************************************************************
ZX-80/ZX-81 and derivatives
Original driver by:
Juergen Buchmueller, Dec 1999
Fixes and additions by Krzysztof Strzecha:
07.06.2004 Tape loading added. Some cleanups of debug code.
Fixed stupid bug in timings (vblank duration).
GAME_NOT_WORKING flag removed.
29.05.2004 CPU clock, number of scanlines, vblank duration corrected.
Some cleanups. Two non-working TESTDRIVERS added.
14.05.2004 Finally fixed and readded.
Changes done by Robbbert in Jan 2009:
- Added the NTSC/PAL diode to all systems except pc8300 which doesn't support it.
- Applied NTSC timings to pc8300 only, all others depend on the diode.
- Many keyboard fixes, and descriptions added to keys.
- Fixed .O files from causing an access violation.
- Enabled cassette saving.
- Many general fixes to pow3000/lambda.
- Added sound to pc8300/pow3000/lambda.
24/12/2009 (Robbbert)
- Added rom mirror, this fixes ringo470
- Added back the F4 character display
14/08/2011 (Robbbert)
- Modernised.
To do / problems:
- Halt-on-nmi emulation needs a cycle-exact z80
- Some memory areas are not mirrored as they should.
- The screen in pc8300/pow3000/lambda jumps when you type something.
- lambda/pow3000 32k memory pack is unemulated, because where is the upper 16k mirror going to be?
- h4th and tree4th need their address maps worked out (eg, the stack is set to FB80)
- lambda/pow3000 joystick, connected in parallel with the 4,R,F,7,U keys, but the directions are unknown.
- Many games don't work.
- sets lambda. pc8300, pow3000 all fail to show text.
