I've found that the TU58 emulator discussed above will not run under Windows
NT - it will not even extract! It does extract under Win 98, and runs (and
extracts) well under DOS 6.22
I'll let you know if it works with my 11/23+ tomorrow, I should at least be
able to make an image of (part of) my XXDP disk, though it depends whether I
can configure SLU2 (on the CPU board) as the TU58 port.
Am I correct in thinking that XXDP(V2.3) will assign a DD drive number for
the TU58? (it calls my RL02 DL0).
Jim.

Hi people,
on my PDP11/23+ there is that key called "AUX POWER". But it doesn't do
anything on my machine. The only power switch is at the back of my
machine. And there is an unused connector at the back of the front
panel. From that little panel goes a cable to the back of the PDP which
ends in an unused connector, too.
Somebody said something about a power bus?? I have not found the posting...
Does a fancy power switching (everything in the rack at once) system
exist? If yes, what do I need to get my rack complete?
Best regards,
Philipp :-)

Of the PDP-11 OSs RT-11 has the fewest requirements to run.

Northern NJ (Ridgewood, 07450). I don't have a Compaq Portable III. I
have what I believe is the ORIGINAL Compaq. Their luggable suitcase sized
thing with dual floppies, and 5 in screen in a nice luggable case.
I'd suspect I can probably sell it on ebay, but at this point, I've been
thinking of doing that for a very long time, haven't gotten around to it,
and now just want to get rid of them. There is at least one, maybe two (I
think it is two Corona's, one complete, one missing the keyboard case/top
cover, and one complete compaq).

I picked up a sack full of these
<http://www.classiccmp.org/hp/PDP-8%20cards/cab-kit.jpg> last week. Thom
says that they're valuable but I was just going to rob so parts out of
them. If they're worth much I'll use them for trading material or E-bay
them. if they're not worth much, I'll just pull the parts that I want and
pitch the rest.

Hi Rich
There is a separate mail group called sebhc that
is specifically early Heathkit. It has a ftp that
we have collected various images of HDOS and HUG disk
as well as some documentation. I'm sure it would be
great to have it sent there. There has been some
recent discussion with some of the other authors
of HDOS that also participate on that group that
none of them have saved any of the source code.
I am forwarding your message to that group as well.

Here is a collection of cards that I found in various DEC PDP-8 chassis
last week. Can anyone id them?
<http://www.classiccmp.org/hp/PDP-8%20cards/CESI%20LPC8.jpg> Marked CESI
and LPC8. I'm guessing that it's a line printer interface for the PDP-8. It
has a 40 pin ribbon cable header on it.
<http://www.classiccmp.org/hp/PDP-8%20cards/Emulex%20TU1110406.jpg> Made
by Emulex and marked TU1110406 2A. Looks like some kind of tape controller
to me. It has two 40 pin ribbon cable headers on it. The LH one is marked
To TC01 or TC11 and the RH one is marked To Tape Deck. The rotary knobs on
the lower RH edge select speeds of OFF, 125 ipc, 75 ips, 45 ips or 37.5/25
ips.
This one
<http://www.classiccmp.org/hp/PDP-8%20cards/PN%203021%206002.jpg> has a
symbol that looks like the National Semiconductor symbol but it has three
lightning bolts instead of two. It also has the number 3021 6002 on it. The
cables have been cut off so I have no idea what was on the other end of them.
The only marking on this one
<http://www.classiccmp.org/hp/PDP-8%20cards/PN%20140014.jpg> is the number
140014.
This card
<http://www.classiccmp.org/hp/PDP-8%20cards/XEBEC%2001-100968.jpg> was made
by XEBEC and has the number 01-100968 on it. It has two 50 pin ribbon cable
headers on it.
This card <http://www.classiccmp.org/hp/PDP-8%20cards/OTR%20120.jpg> was
made by Computer Idenitics Corp and says that it's an OTR-120 interface.
(Optical Tape Reader?)
The rest of the photo in the same directory are DEC cards for my PDP-8
with the exception of the Plessey RK-05 disk drive controller set (3 cards).
BTW Thom is cleaning up and found 198 various disk cartridges yesterday.
Many of them contain software, diagnostics and/or Operating Systems. If
anyone needs any cartridges he's looking to sell all of them so give him a
call. And yes, he does have some alignment packs, CE packs, etc but he'll
want real money for them!
