Caveat: I do not own an ST and have not seen any of the documentation that is provided with it. First the dma port ... can someone tell me what the pin assignments are and the associated protocol ? Cartridge port ... can this be written by the 68000 or just read? Are the right lines provided so that an active device can read and write main memory from the port? Can someone suggest a fairly reliable document (cheap) that can answer questions like the above. -- eric h. jensen (S1 Project @ Lawrence Livermore National Laboratory) Phone: (415) 423-0229 USMail: LLNL, P.O.
