Asteroids Deluxe resurrection
ChadTower:
Hrm, looks like Bob Roberts has the Op Amps and a nice looking VR kit full of common VRs. I'll have to make ANOTHER order from him. Heh. At least he cross ships again, so I'm getting my stuff really quickly. Sucks to pay $6 shipping every time for these tiny things though.
ChadTower:
Research update:
The DACs appear to be AM6012ADC, and are located at A/B11 and C/D11.
ChadTower:
Hrm... Peale asked me how many pins are in the DAC, and I looked at the schematic to check. I only see two of these DACs in the schematic, each halfway between the letters in the grid. Maybe A/B11 means "11 at halfway between A and B", which means I only have two potential culprits. At $11 each, that's quite a difference.
fredster:
I think you are right, a/b11 is the chip in between A and B, but are you sure that Bob's chips will work? Did Bob tell you that?
ChadTower:
Page 33 of the AD manual tells me that Bob's chips will work.
