Gorf Posted December 22, 2007 Share Posted December 22, 2007 the "Magic RAM" chip is a bit more powerful since it's also able to rotate things while writing to the RAM (which it can't do on the Actually...almost correct.... The Astrocade home hardware is the same exact chipset....it cant use rotate because rotate is only available in high-rez mode. Yes....you can mod up the Astrocade for high rez mode also by finding 3 more banks of the same 4k by 4 bit rams (or 8x4 or 16x four) and a flipflop. You piggy back three more sets of chips on top of the exsisting ones and bend up a certain pin on each. I know this to be true as I was told this by none other than Bob Ogdon, one of the hardwares creators. He said you can even use an unused flipflop already inside the astrocade to do this. Trouble is the Astrocade OS is written for lo-rez and anygame you wrote for the new mode would need all the built ins of the rom to be rewritten to deal with the doubled rez. What I have here is a home Astrocade..the Gorf, WOW, Robby Roto, space Zap rack version and an astrocade high rez version(yes it is a LARGE looking astrocade board) that they never did sell at home but instead used int he Arcade machines, Sea Wolf II, Professor Pacman and Extra Bases games. I'll dig them out and take a pic or two of the later two as there are plenty of spots to see a home Astrocade. Quote Link to comment Share on other sites More sharing options...

No way to do this through the expansion port? Quote Link to comment Share on other sites More sharing options...

No way to do this through the expansion port? No and Bob explained to me something of the nature of the bus setup. I used to know this stuff verbatim but its been a while. Signals necessary to allow this on the expansion dont exsist. I foget which though. It's something to do with how the system multiplexes memory if I remember correctly. I'll take a peek and report.

TimsterAA Posted June 26, 2008 Share Posted June 26, 2008 Put me in the line for a Bally "War" cart once it's completed!!! --Timster-- Quote Link to comment Share on other sites More sharing options...
riffraff Posted June 30, 2008 Author Share Posted June 30, 2008 It's actually been completed for a long time. Just haven't had time to get a label/manual going for it. Adam and the guys at Bally Alley are helping out with that. Should get going with it in a month or so. Quote Link to comment Share on other sites More sharing options...
