Re: Battlezone Aux Board replacement?

There are actually some AM2901 VHDL sources if you google !! (don't know how reliable they are though) - Way over my head though !! -  So.. Mame Simulates it instead of emulating it..
 
Yes I agree Tom - Fairly easy fix as there's not too much to go wrong..

Even better Battlezone schematics:

Mathbox simulation in MAME:

POKEY emulator in MAME:
http://maws.mameworld.info/maws/mamesrc/src/emu/sound/pokey.c

And speaking of Battlezone, I was playing around with a Battlezone and G05 a few nights ago. I was reminded that not everyone has a vector pattern generator with which to test their various vector monitors.

Why wouldn't someone recreate a simple vector pattern generator, rather than a somewhat obscure mathbox? Everyone with a vector game needs a patern generator, but noteveryone *needs* a mathbox (which are mostly simple to fix).

Ed, can you get on that for me?
