Novag Super System Peripheral: TV Interface
|
||||
|
||||
It's meant to be connected either like: PC -> Distributor -> TV Interface, or
|
||||
like: chesscomputer -> Distributor -> TV Interface. But the distributor is only
|
||||
for converting to/from RS-232/TTL voltage, so MAME can ignore it.
|
||||
|
||||
It expects a baud rate of 9600, 8 data bits, 1 stop bit, no parity.
|
||||
|
||||
Hardware notes:
|
||||
- PCB label: 100122 REV C
|
||||
- Hitachi HD63A03RP @ 4.9152MHz
|
||||
- 8KB ROM (27C64A), 4KB RAM (2*UM6116-3)
|
||||
- TMT TM6310 CGA chip, 14.318MHz XTAL, 8KB CG ROM (27C64A, only 2KB used)
|
||||
|
||||
TODO:
|
||||
- dump/add English version
|
||||
- Currently, MAME only has CGA emulation on ISA cards, but this thing is not an
|
||||
ISA card, nor compatible with IBM CGA standard. So if MAME ever adds a more
|
||||
generic CGA device, use that.
