Hi list,
After some non-sleeping nights the QBUS MSCP SCSI controller is now
usable except that it is still controlled by the PC. I installed
NetBSD 1.5.2 and ran "cp base.tgz /dev/null", and the speed tested was
840KB/s. I am wondering how fast those commercial controllers are. I
would appreciate it if those of you who own those boards could let me
know. The design goal is to approach the fastest.
I believe the CMD controllers are supposed to be the fastest,
something else to consider is that the Q-Bus itself is only something
like 3.5MB/Sec (does anyone happen to remember the exact numbers).
If I can find the time, I can run a test under RT-11 on my PDP-11
(Viking QDT).
