Miss Americana
© 1984 Sirmo
"Bingo Pinball" style game.
Hardware:
- P8085A
- 6.144 MHz XTAL
- 3x P8155
TODO:
- The "Magic Lines" feature isn't emulated
- There is no ball physics simulation
- Sound isn't emulated at all (you can see triggers on the artwork)
- The optional hardware random number generator isn't emulated (see DSW D)
- Output counters
- Verify/measure clocks
- "Telephone" input/output (probably just a remote control?)
Notes:
- It will display the error "cccc" on cold boot. Just push F3 once
to reset and initialize
- Blinking tilt led means "normal operation"
- The service mode supports viewing and changing all memory values as
well as an output (SV5) and input (SV6) test
