Hi all --
Making some progress with the "fire sale" PDP-11/70. Over the past month
I've rebuilt the power supplies and burned them in on the bench, and I've
gotten things cleaned up and reassembled. I'm still waiting on some new
chassis fans but my curiosity overwhelmed my caution and I decided
Hi Josh,
ZAP is effectively reset for the micro-architecture, forcing the ucode address
to known/initial value. It has multiple sources throughout the processor,
including tendrils into some of trap handling hardware. (Caveat: my experience
is based off extensive work with the '11/45, but the

Did you check to make sure that power is wired correctly to the
PEP-70/Hypercache? They are typically installed in "empty" slots and
don't have power (or anything else) routed to them. They require some
additional jumpers to be installed on the backplane so that they get power.

Hi Thomas,
Did you ever the pdf copies of these?
I also would like to get a set.
Thanks,

Yup -- I'm surprised how picky my '45 is about +5 undervolt; it really seems

Hmm, would expect to see S2:1 S1:0 step by microinstruction, and S2:1 S1:1 step

Greetings
I recently purchased a QCS external hard disk on ebay. This was one of the
companies that was selling DEC Rainbow hard drives. I had hoped it was an
old Rainbow drive with interesting to me bits... Turns out it is an Epson
QX-10 hard drive, full of interesting to bits for the QX-10 CP/M

Thanks Noel,
Yes, I tried to repair an 11/34 once after somebody plugged a peripheral
board into a memory slot - I was doing well after 3 or 4 chip chnages,
it started to come to life, until I found the 20V went right into an
d=address line of an in-house numbered ROM!
Having been warned by
Not so lucky n Canada! They wanted $28 shipping!
So I got a box of 10 for $28 - but delivery end of Feb.
Back burner until then!
Thanks

Hopefully we can turn up some poster art and other things to
Interesting. I have a Contemporary Cybernetics 8505 drive that I think
used the Exabyte tape system, will have to dig it out and see what it
looks like. Used them at the IEEE Computer Society for years but finally
went with IBM LTO tape libraries at Science. The LTOs were more reliable.

I only have the S (well, there is a second one in the basement I need to
drag up). I did have one of those little 4 slot dual width boxes that
had a power supply but I sold it. Wouldn't help with quad width modules
anyway.
There's another BA23 down there, I'll probably try to haul it up next
