Hallo allemaal, I'm sorry to say but it seems for the moment I cannot forfill my promise. I realy do have problems with decoding the signals towards the various registers and lines. I tried to combine three features: - C64 <-> ISA, 8 + 16 bit transfers - DMA: - ISA <-> ISA - ISA <-> C64 - C64 <-> C64 That results in about 8 inputs and 12 outputs. Why "about"? This has to do with the R/W signal. One moment it is generated by the C64, the other moment by the 8237. This results in a table with only 32 lines. This is not that much one would say, but stil.... :( There are several solutions: - anybody offers help in the form of "step-by-step" evaluation of the decoding - I simplify the goal: - C64 <-> ISA, 8 + 16 bit transfers (some restrictions on 16-bit part) - DMA, C64 <-> ISA, 8-bit I/O only Any comment/help through the list or to private email (include G.Baltissen (at) hccnet.nl as well) is welcome.
