- Problem solved.
- It was a combination of termination and that I copied to this SCSI from
- my old IDE on a ZorroII SCSI controller. The mask was set for a 24bit databus
- and I guess that made all my transfer go through chipmem even though they
- should go directly to fastmem...
-
- Now I get 1.5MB/s reading with 32kb buffer and that's ok.
