Does anybody have drawings on the TU10 dec magtape?
Mine has stopped working. The vacuum sucker don't suck anymore
(is it a sucker?). Please let me know if you have, and
if you can spare me a copy. (I'll even pay for it).

I know this list is primarily for pdp8's, but I was curious if
anyone knows if there is an existing dec-10 running on tops10.
I haven't heard of anything running tops-10 for awhile now...

The one I used was retired 4 years ago and I still miss it.
Nothing like a good game of DECWAR to keep ya going!!  I am in
major nostalgia mode, so any information would be neat.
Thanks.

kicki.stacken.kth.se is a PDP-10 (KI twins) running 7.02C (I think).
I don't know if you can get an account on it (you should be able to).
It's down alot and when it gets fixed, it runs fine.

It's usually not down a lot, but Peter is in the process of moving the
whole system. He has also had some nasty system krasches a couple of
weeks ago which has brought the whole thing down. Anyway, mail to
[email-masked] will probably be most effective (if the mail
doesn't get through, there's no point in asking for an account at this time).
BTW, I think it's running 7.03.

Cheers,

PS I thought this list was for "PDP-8 and *other* vintage DEC computers" so
discussing PDP-10's should be OK, right??

I did this in college, and amazingly I cannot remember my solution.
(It was written in the margin of my book...) However, here's one I did
come up with (I know it's not the same as my original, which had no JMS
instruction).  Like Robert, I can't test this one.
----------------------------------------------------
/This program clears all of a 4K PDP-8's memory.
/Start reading at "start".

*0
/... and this last instruction first increments auto10 to zero,
/then stores a zero at location zero, finishing the job.
        dca i 10
loc1,   11
        0
        0
        0
        0
        0
        0
auto10, loop

*7772
start,  cla
/The next three lines clear from 11 through loop,
/then increment location 1 until it's zero.
/After this, all that remains nonzero are locs 0, 10 and loop+1 through 7777.
loop,   dca i loc1
        isz loc1
        jmp loop
/The previous jmp is dangerous, so nuke it now.
        dca .-1
/Here's the fun part:
/We are at location 7777, so the return address of a jms from here (the
/number stored at the target address) is 0.  Thus this next instruction
/first zeros the isz, then we wander back to zero the (already zeroed) jmp,
/then the dca and finally this instruction itself, when we find memory
/clear but for locations 0 and auto10, and we are
/executing at location 0 with auto10 containing 7777...
        jms i auto10

Subject: re: tops10

Last I knew Compuserve was 39 10's.  Since Compuserve id's are things like
3124,23423 , I always assumed they ran tops-10.  I have a picture (a few years
old, admittedly) that shows a bunch of KI's with scads of DECtape. A KI was my
first real machine to work on, at the Alcoa Technical Center near New
Kensington, PA.  Ran TOPS-10.  While I was around (as an Explorer) they
upgraded it to a KL.  I'm not sure if they still have it.

A couple years ago at CMU the CS department stuck the venerable cmucsb out into
the hallway.  Here's what it had:

Needless to say, it was a looooooooooong hallway.  cm* was next to it.

As DIGEX, who knows more about these things than I do will be happy
to attest, the key is "ran".  Compuserve's machines run an operating
system that _used to be_ tops-10, but has been hacked and modified
beyond belief.  They started out with KAs and KIs; I'm pretty sure I
heard that there are no more KAs there.  There may be some KIs left,
but I would guess that the majority of what they have these days are
KLs.  They are probably the largest commercial user of DECsystem 10s
(note the capitalization - it's DECsystem 10, DECSYSTEM 20...) left
in the world.  Maybe the largest that ever was.

Anyway, as previously noted, KICKI, a machine at Stacken, the computer
club at the Royal Institute of Technology in Stockholm, Sweden, is
to my knowledge, the only TOPS-10 machine on the Internet today.
It is a 3-processor KI-10 (usually running in a 2-processor configuration
due to power considerations), which runs a version of TOPS that was
hacked to allow symmetric multiprocessing (SMP), which is normally
only available on KLs.  Although KICKI is the only DEC-10 at the
Royal Institute of Technology that's on the Internet, there are
others there that you can connect to via the ANF-10 front ends.
Try a "set host" to ODEN, NADJA, and AURORA.  ODEN is a dual-processor
KL, NADJA and AURORA are DECSYSTEM 2020s, running Tops-10.

I'm looking for some more hardware to my little beauty.
Specifically:

KP8-E Powerfail autorestart option (M848 I believe)
KT8-A Memory Management Option
KL8-A Serial line multiplexer

I doubt that the last two items is easily found, but I can
always hope.
I anybody got any of this stuff, and is willing to give, sell
or exchange this with other stuff, let me know.

Now to stuff I have in excess, if anybody need any of this, let me know.
Positive I/O bus interface (lots of them)
KK8-A (that's a pdp8/a CPU) (one)
KM8-A and DKC8-AA (one of each) (this is the two option boards for the
8/a, both are faulty, but should be easy to fix, since it is no
big faults, I can tell exactly what faults they have...)
KK8-E (that's the pdp8/e CPU) (one)

Also, of anybody has KL8-JA Terminal boards over, I'd be interested.
KL8-E might be nice too, but I prefer -JA, since I have a plan for
modifying them to have software settable speed.

For all you guys interested in real machines, there is a pdp8/i
called CRAP-1 here at Uppsala, which can be reached by telnet.
It has the address CRAP.UPDATE.UU.SE (130.238.64.151)
The machine only has DECtape, so give it some time to respond.
It has, however recently (at long last) been upgraded to OS/8 V3D :-)
Please do not scratch any tapes, or run BUILD with funny parameters...
Have as much fun as you like... (isn't old machines beautiful...)

I think I have a KP8-E powerfail unit somewhere around here... 
lemme look.

Excellent find last night...  I was digging around in the
attic of Dupont Hall at the U of Delaware with some friends of 
mine, and one of them said "Hey, I know where there are some
*unused* DECtapes...".  Well, we went there, and there were
no DECtapes to be found, but what he was referrinng to as
DECtapes was actually a whole case of virgin DEC non-oiled 
paper tape...

I have an RK8E controller board set which I would be willing to
swap for an:
              RX8E - RX Disk Controller
              RL8A - RL Disk Controller
              FPP8A - Floating Point Processor

I would be willing to add some cash for the RL8A and FPP8A.

I also require a PC8-E reader/punch controller (M840) which I
would like to purchase outright.

I own a rather large number of PDP-11 Unibus cards and would
also invite offers to sell or swap these for Omnibus,  or
Qbus boards.
