Hi Sirs, I would like to abuse the Atari harddisk SH204 as a disk in a transputer system. Therefore a simple transputer link to ASCI bus interface is to be build. But due to lack of documentation I do not know the required handshake timing diagrams of the Datarequest (DRQ) and Acknowledge (ACK) signals. My questions: Does someone outside know the timing specification for the asynchronous protocol of the harddisk ? I have seen a cycle time of about 750 ns for one byte transfer controlled by DRQ ACK signals driven by Atari St. Is it feasible to work with a cycle time of approximately 1300 ns ? Does someone know where to get authorized documentation for the harddisk ? *Any* information about the disk is appreciated.
