/***************************************************************************
Laser Compumate2
17/04/2011 Initial driver by Robbbert, using info supplied by
DMEnduro. He owns one of these machines.
21/04/2011 Hooked up the lcd controller and added keyboard
input. [Sandro Ronco]
22/04/2011 Small adjustments resulting from team investigations.
Chips: Z80 CPU, 8K of RAM, 32K ROM, 'VTCL', '8826KX',
RP5C15 RTC.
Display: 2 lines of 20 characters LCD.
There are no devices for file saving or loading, is more of
a PDA format with all programs (address book, etc) in the ROM.
Sound: a piezo speaker.
ToDo:
- RTC doesn't remember the time
- Alarm doesn't work
- Reset/On button to be added
- The ROM has INT and NMI code; investigate if something uses it.
