Pertec interface

For one, it does a lot of buffering, so the data transfer rate (from first byte to the last) is exactly the same for 1600 as it is for 6250. And that's the maximum 1.1MHz that the Pertec interface is rated for. Many simple ISA interface cards have trouble doing a sustained transfer at this rate. The high-end ones with local buffering should handle things a bit better. When a Pertec-interface drive is reading, there's no handshake for data transfer to the host--the drive simply puts the data on the read lines and pulses a strobe line--you're expected to be there to catch it. Other than the data transfer issues, a Pertec interface is a very simple thing and you could probably work up your own interface without too much difficulty. Cheers, Chuck
