So do you suppose it would be possible to take a shot at figuring
out how the thing works? I have no drivers for it. I could look up
what the 164P is wired to, saturday or monday. Do you think it would
be feasible to develop a driver for it?
too
Hitachi
HD74LS32P
Quad 2-input OR gate.
367AP
Is that another chip? If so, its a hex 3-state buffer
240P
And that's an octal inverting 3-state buffer
164P
And a shift register (odd...)
MB74LS00
Quad 2 input AND gate
138
3-8 line decoder.
TI J549X SN74LS541N
Octal 3-state buffer.
Probably some kind of address decoder (the '138) and buffers. Nothing unusual (although what the '164 is doing I
don't know).
