Schachcomputer SC 1 driver
|
||||
|
||||
VEB Mikroelektronik's 1st chess computer. It was canceled before wide release.
|
||||
This appears to be a prototype of SLC 1, it's definitely not VEB SC 1.
|
||||
|
||||
TODO:
|
||||
- speaker, it's very noisy if hooked up as it is now, missing enable-bit?
|
||||
it still toggles matrix d1 if T(tone off) is pressed
|
||||
- LEDs, they're not on digit d7
|
||||
- merge with slc1.cpp? but hardware differs too much
|
||||
- any way to access the "Lern" part?
|
||||
- speaker, it's very noisy if hooked up as it is now
|
||||
- LED(s)? they're not on digit d7
|
||||
- 7seg sometimes flashes
|
||||
- setting level doesn't work? game should boot with "PS 1"
