I'm trying to keep the scope within the realms of sanity.
So I'm placing initial limits on the hardware upgrade.
Required outcome: Upgrade the Poly 800 RAM and ROM to support
additional CPU programming related functions. A board will be
developed as part of a retrofit kit that will plug into the existing
ROM socket. The card will have a 2764 EPROM, a 6264 RAM, a 74LS138
decoder.
Optional outcome: Provide the needed hardware to integrate several
well established mod's (moog slayer, 12/24db filter switch, etc) into
the CPU control and user programming system. Thus, add a 74H174 (6 bit
latch) and a digital potentiometer and other chips as needed to allow
existing and future mod's to be controlled by the CPU.
I think it very unlikely that we'll run out of CPU cycles handling the
required outcomes. I think it possible that we may run into CPU cycle
restrictions trying to satisfy the optional outcomes.
If we do find that we run out of CPU cycles then I'm hoping that I'll
know so much about the code that I can port the whole thing to a PC
and release a virtual Poly 800 that will run on your Linux box.
