We are planning to use a Western Digital WD33C93A SCSI controller chip in a DSP system to allow large amounts of sampled data to be stored on disk. The only data sheet available from the swiss representative of WD is a 'Preliminary Engineering Specification' dated March 13, 1987. Is anybody aware of a newer version of this document? Thanks for your help! Norbert Hanke ETH Zurich, Switzerland

I am using the AMD book, Rev A., dated June, 1989. It is reasonable for a chip spec but no ap-notes. I have been struggling a bit with it. It is quite involved and could really use some ap-notes or a programmer's reference.

For programming the WD33C93 there is an Application Note from Western Digital: WD33C92 and WD33C93 SCSI Bus Interface Controller Starter Kit V1.0 Western Digital Corp. Applications Engineering, November 1986 written by John Spongr (WD Document No. 79-000116) There are also some Application Notes available on how to connect the Device to Intel-type CPU's. It was VERY difficult, to get these Notes from WD .... ------------------------------------------------------------------------------ hellmuth michaelis helle@ktshh / ...!lutzifer!ktshh!helle voice: +49 40 384298 hm@hcshh / ...!mcsun!unido!hcshh!hm ------------------------------------------------------------------------------
