Primo driver by Krzysztof Strzecha
What's new:
-----------
2009.07.19 - Removed hacked and duplicated ROMs (Krzysztof Strzecha)
2008.08.31 - Added new ROMs including B32 and B48 [Miodrag Milanovic]
2005.05.19 - Primo B-32 and B-48 testdrivers added.
2005.05.15 - EPROM+RAM expansion.
Support for .pp files improved.
Some cleanups.
2005.05.12 - Memory fixed for A-48 model what make it fully working.
Fixed address of second video memory area.
To do:
1. Disk
2. V.24 / tape control
3. CDOS autoboot
4. Joystick
5. Printer
6. .PRI format
Primo variants:
A-32 - 16kB RAM + 16KB ROM
A-48 - 32kB RAM + 16KB ROM
A-64 - 48kB RAM + 16KB ROM
B-32 - 16kB RAM + 16KB ROM
B-48 - 32kB RAM + 16KB ROM
B-64 - 48kB RAM + 16KB ROM
CPU:
U880D (DDR clone of Z80), 2.5 MHz

ToDO:
- primoc64 works, but it seems it should be used with a commodore 64
disk drive. This isn't emulated.
