Hardware notes (2-ROM version from schematics):
|
||||
- UD880D CPU (Z80 clone) @ D201, ~900kHz no XTAL
|
||||
- 2KB ROM (2*U505D @ D202/D203)
|
||||
- 1KB RAM (2*U214D @ D204/D205)
|
||||
- 2*UD855D (Z80 PIO clone) @ D206/D207
|
||||
- UD857D (Z80 CTC clone) @ D208
|
||||
- cassette port
|
||||
- 6*7seg display, 2 leds, piezo
|
||||
|
||||
The PCB is literally inside a map that can be closed like a book.
|
||||
It has a nice calculator style keypad attached to it.
|
||||
|
||||
The memory can be expanded. There's an export version with more
|
||||
RAM/ROM by default, and it included a chess program called SC-80.
|
||||
SC-80 starts at ADR C8000.
