Hi,
I have a DEC Rainbow that I want to pass onto another collector. I live in
Cambridge UK, and while I can deliver for a short distance collection
would be the best as there are quite a few manuals that go with it.
Drop me an email if you are interested

Hi,
I have a HP 9000/217 that I want to pass onto another collector. As with
the Rainbow previously, it would be best if you could collect from
Cambridge UK, but I could be persuaded to deliver as long as it's not too
far away. To see a picture of the machine in question go to:

Drop me an email if you are interested.

Back when I asked about the HP 3000, someone mentioned that it
processed data in blocks. What exactly does that mean? How does it
work?

I had some neat old gear once, that I enjoyed playing with. Including a
couple PDP-12s, 15s, 8s, a Linc-8... quite a variety actually.
Anyone know of any place with some stuff like that available, for sale?
I'd like to have some of that again, both for my own enjoyment and to be
able to show some people how things used to be.

Well, muchas gracias to Mr. Duell; I have one of my 11s out of
deep sleep and talking to it's console. For any who have followed
this sequence.. the problems resolved to a) bad BA11 (PSUs good,
something else is wrong) b) the old grant continuity confusion, and
finally c) a bad RS232 cable I put in the line to the console VT100
to extend it a bit.
So now, I have one 11/34 computer running, with an RX02 (but no
bootable media for it) and two RK05s, neither of which work at the
moment.... but that's the next hurdle.
Actually, I have configured a single RK as unit 0 and terminated
it. The *problem* is something in the control logic preventing the
unit from spinning up the disc and coming into ready. So I'm
kneeling on the floor under the drive with a voltmeter and a scope,
trying to find where the chain is broken. At least I have extender
cards....
Again, many many thanks to all of you who have taken the time to
offer advice... it was correct and successful.
More later as the situation progresses..
Cheers
John
Thanks first to all who have offered help and advice. (Re:
sacrifices... roosters have psitticosis and mites, and as for
virgins... c'mon guys, I'm in *California*.... <g>)
The computer works; the disk drives don't. Armed with the
printsets for the drive and the controller, and assisted by the Group,
I am reasonably certain that thr RK05 itself is in good shape. I
have simulated all it's 'ready' conditions and it's fine. I have
changed (twice... aarrghhh) the interface cable... all same.
The RK05 thinks that DCLO is asserted. "Forcing' DCLO at the drive
makes it work. I have measured DCLO and ACLO at the RK11D
backplane.. they are at +5V. In the drive, +30VAC is good into the
control card. On the RK11D, I have traced DCLO to the wirewrap pins,
and it appears good. I have yet to figure out the path DCLO takes
thru the RK11 stack. This problem has been most baffling so far
because DCLO originates in the RK05 and in the RK11 and in the
BA-11.. so it's a multiple-varible with a commaon symptom. I seem
to be converging on it, but if anything jumps out at someone with
some actual field experience with these devices... it might save me
a few more hours of discovering all the various places where the
problem "isn't". ;}
To Tony Duell: thanks for the e-mail.. I did indeed verify the
itms you mentioned... the 'interlock' circuits are working,
microswitches good, etc.
ALSO: I would love to have a pointer to the D11W SLU/LTC card
switch settings... at least the baud rate stuff... I want to use my
LA120 as a console rather than the VT100... getting Unix going is
next after the drives a working, and I want hard copy for that. I
have looked and not found this particular info on the Net so far.
Cheers to all
John

The Apple IIgs was code named "Cortland", "Phoenix", "Rambo", and "Gumby".

Well, it also helps to have a shell. That's why I also brought
that 9134 disc drive -- it has the development set loaded on it,
which makes it behave a bit more like a Un*x box.
Failing that, PAM has a little bit of shell functionality in it. You
can use it to look at text files, also you can get a list of files in
your current directory by typing "echo *" in its command-line area.
(No, PAM doesn't show you everything.)

Tony mentioned HP-IL and that made me think of what I've been plodding
through today: a box full of HP-41 and HP-IL documentation. Shame I
didn't grab any of the hardware (other folks did, and left the manuals
-- so far as hardware I was concentrating on 9114s that I knew I could
use with my Portable Plus and some other little bits), but maybe next
time I cross the path of some I'll have a better idea of what to look
for.
So what have I got? Well, thus far:
The HP-IL Interface Specification
p/n 82166-90017, Nov 1982
HP 00041-15043 HP-IL Development Module Owner's Manual
p/n 00041-90449 Rev B, Oct 1984
1LB3-0003 The HP-IL Integrated Circuit User's Manual
p/n 82166-90016 Rev B, Nov 1983
HP 82166C The HP-IL Interface Kit Technical Guide
p/n 82166-90020 Rev B, May 1983
HP 82166A HP-IL Converter Technical Manual
p/n 82166-90002, Nov 1982
HP 82165A HP-IL/GPIO Interface HP 81266A HP-IL Converter Manual Supplement
p/n 82165-90012, Oct 1982
OK, that is what I found in the first binder. Somehow I have a feeling
I'm gonna wish I had Tony's clues by the time I get done with this.

it's my understanding that the //c's ps will work with the laser. i think the
connection is the same, and the voltages are slightly different, but close
enough to get it to work.
In a message dated 98-05-27 15:04:32 EDT, you write:
