09/13/04 There was no MPU-401 chip that I could locate. The largest chip is: TL16C552FN (next line) 73A62JW (next line) B The second largest chip is: Dallas DS80C320 (next line) 975185-QCG From a Google search on the DS80C320 chip: The Dallas Semiconductor DS80C320 is an 8051 based High-Speed Micro with 2 DPTRs, WDT, Two Serial Ports, 32 I/O lines, 3 Timers/Counters, 13 Interrupts/3 Priority levels, ROM-less, 256 Bytes On-chip RAM. My guess is that this is the chip that drives the card. I'm downloading the High Speed Users Guide PDF right now, but I never really got into writing drivers. From a Google search on the TL16C552FN chip, all that readily appeared were prices and vendors. Thanks for the reply, Sampo. Stephen. > Can you tell if there is a chip labeled MPU-401.
