mw8080bw: new netlist audio implementation for 280zzzap
New netlist-based audio implementation for 280zzzap (280-ZZZAP, 1976), derived from Midway game logic board schematic.
This netlist, with some modifications for differences in components and circuits, should also be able to support Laguna Racer and Super Speed Race. -
While lurking/visiting Bannister's shoutbox...
Colin Howell: speaking of PCB photos, are there any good photos of Midway's 280-ZZZAP game logic board (the one with the sound circuits)? It seems hard to find good-quality PCB photos online, but maybe people hide them to deter eBay scammers and suchlike... Colin Howell: (it would also be nice if a copy of the game's parts catalog could be scanned and made available, so as to compare the PCB physical layout schematic with the functional schematic and check for discrepancies. Colin Howell: I know such a catalog exists, but even though the game logic board functional schematic has been scanned, the full catalog apparently never has.
....and for those that have time to forward info over to Bannister's forum.
Those glossy 1970s era Midway parts catalog only have the cab parts and pieces. The pcb components pages are usually on separate letter size paper, stapled together with listing components and indicating what each component is on the pcb and then resistors, capacitors, xtal....etc
