Hi all!
I noticed that while the Emulex SC03-B1 manual is on Bitsavers, the instructions for how
to patch and use this board on a 22 bit Q Bus system are not. In the manual it says to
"Write emulex".
Fortunately I did 40 years ago and I have the "Emulex Disk Capacity Patches to DEC
PDP-11 Operating Systems" manual which is now scanned and online
athttps://www.crystel.com/dec/sc03
Emulex document ID is PD9951002 Rev A, March 1983. Covers Rsx11M 3.2, 4.0,
RSTS/E, and M+ versions at that time.
Every page is scanned as a 300 DPI TIFF image, and there is a PDF version of
the whole manual as well.
Apparently they use the RH70 Unibus driver (which supports 22 bit without the
unibus map) and then change a few bits to make it work on Q Bus.
Enjoy and bitsavers owner please stick this in your archives as well.
