[comp.sys.atari.st.tech] Exabyte 8mm tape drive and TT030

vspicer@ccu.umanitoba.ca (05/03/91)

I am currently attempting to get our TT030 to talk to an exabyte EXB8200
tape drive through the TT's SCSI port. Does anyone have code for communicating 
with the SCSI port? I've gone through the manufactuer's data sheet on the
5380 SCSI controller chip, and it's registers are mapped into TT addressable
memory ($8780-$878E).
The new Xbios call 0x2a/0x2b (DMA read/write) don't do anything; the routine
returns a -1 error code. It was a long shot anyway, since it deals in
"sectors" (hard disk devices only, i guess). Even the address for where
this particular call is located would give me a place to start.

thanks in advance
