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 at https://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.

In the early 70s I worked at a place that had 2 S360/40s. On the 23rd floor of a 45+ year old building. At least 8 tape drives, 2 control units for them, 2 full banks of 2314, 2 1403 printers and 2 2540 card machines.
I would assume updated wiring would have to have been run up 23 floors. When I started there was 1 S360/30. Don’t know if the normal building wiring would need to be updated for that.
I, for one, have fond memories of the S/360-20, 30 and 40. I ‘grew’ up running and programming those systems.
FWIW, I have a punch card archive at www.ibmjunkman.com
Does anyone have, or has even seen, a Computer Data Systems "Versatile 2"
s-100 computer from 1977? The company that produced it was from Newark,
Delaware USA and I have been trying to track one down because I live nearby.
Thanks

We're still waiting for VCF PNW 2020, but while we wait ...

(This is a much smaller event than any VCF. It's also quite fun because
it's not overwhelming.)

The Free Software Foundation(FSF) is 40 this week. Central to the thesis of
sharing software this organization has played and continues to play a
seminal role. Though it's importance may be waning due to AI its reason to
exist can't be overstated.
Happy computing
Murray 🙂
