ToDo:
|
||||
- speaker
|
||||
- LEDs
|
||||
VEB Mikroelektronik's 1st chess computer. It was canceled before wide release.
|
||||
|
||||
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
|
||||
- 7seg sometimes flashes
|
||||
- setting level doesn't work? game should boot with "PS 1"
