JPM style Reel MCU? Certainly reel data seems to be muxed together in a weird way
Hardware overview
- Z80
- Z80 (Z8400AB1)
- 8 MHz XTAL
- 3 x TMP8255
- 2 x 8 dip-switches banks
- 2 timed interrupts (IRQ and NMI) (can be reset)
- AY8910 for sound
- TC5517CPL-20
- some of the roms appear to have been merged to larger files, or there are two versions of the board?
