|
||||
Pulsar Little Big Board
|
||||
|
||||
2013-12-29 Skeleton driver.
|
||||
|
||||
Chips: Z80A @4MHz, Z80DART, FD1797-02, 8255A-5, AY-5-8116, MSM5832.
|
||||
Crystals: 4 MHz, 5.0688 MHz
|
||||
|
||||
This is a complete CP/M single-board computer. You needed to supply your own
|
||||
power supply and serial terminal.
|
||||
|
||||
ToDo:
|
||||
- Hook up 8255
|
||||
- Add 5832 rtc
|
||||
- Find out why data from board is corrupt but from keyboard is fine
|
||||
- Need software
|
||||
