Hello! Thought I might bring you an update on the PDP-7.
IT FRIGGIN' POWERED UP!!!!
*ahem*
With shaking hands (afraid the huge caps would explode all over me), on
Wednesday 28th of May, I flipped the magic switch. Nothing happened. I
flipped it again, and it worked. The surprise of it not catching fire was
enough for me to yell without noticing it, "It WORKS, damnit!". I then
proceeded to point at it and make a funny sound. Video of this will come
up on http://tore.nortia.no/video when I have time to digitalize it.
The rest of the day was spent testing the memory and the CPU (which mostly
works). Thursday I tested the IO further, as did I on Friday. I got the
paper tape punch to revolve, and feed at the command of the conveniently
marked "Feed" button on the console.
Now, further I/O repairs need doing, and maybe constructing an emulated
Paper-Tape Reader is nessecary - - if so, I'll hook up the punch to it as
well.
Please see http://tore.nortia.no for continuing coverage. If you ever
worked on this machine, especcialy while on DEC's side, LET ME KNOW!
PLEASE; drop me a line!
And yes, we do have software. Lots and lots of it in good condition. Don't
know about the DECtapes though.
Love, Piece, and Understatements

Hello all,
We have a graphics software package called DIAGRAPH which was released
for HP 9000/200 and HP-150 computers each using a different hardware
protection key.
It turns out that we have the software for the 9000/200 but the key for
the 150.
Can anyone help us recover a working set of software and key?
Regards,
-- hbp
Justin, I read your message from 31-Dec-02 about the LK401. I have a
few new keyboards which you can have.
I used sell this stuff but stopped a few years ago. I hate to just
throw them away. I am in Massachusetts if
you are interested.

I should hedge my bets here: There is no Qbus backplane in the
PDT-11/150. There are some stacking connectors between two dual-
height sized boards (serial ports and memory) on top and the
middle board, which carries the CPU complex. I believe the bottom
board in the stack is the floppy controller - not sure if the
console circuitry (8085 based?) is on that or the middle board.
Now, where on earth do I have the docs for that critter...

Still, it shouldn't hurt to try. The TCM chapter in the manual has
several hints that it may work, but I'm guessing it depends on the type
of protection used.

Yes, although these days it's UUCP over TCP over ADSL. I don't think
either of my upstreams have modems for dial-in UUCP any more.
There was some talk here (or on the old classiccmp list) a while back
about reviving the mapping project, but I don't think it ever came to
anything.

I have for you an NEC pc-8300
and a workslate. The workslate has some software and a pen-plotter
device
Both the NEC and the Workslate itself worked last time I tried them.
I also have a load of MAC laptops and a two or three lunchboxstyle
computers
mostly 386 and 486 and mostly disassembled
In the "real junk" stuff I have a vt220 terminal and a paralell dot
matrix printer that
acted failed when I tried them.
This is just an "off the cuff" list.. expect a more complete list when
I can get a cool morning to
dig up stuff in the garage.
I would like to trade them for somthing...
here is a partial list:
HP 41 calculator (any 41 model)
Rockwell AIM 65
Commodore Portable (I have a 64 that I will add to the deal in this
case.. it works and so does it's 1541)
HP 75 or HP 71 "calculator"
I will entertain other sugestions.
Hi all,
I'm not that familiar with 80 series machines.
Can they be interfaced to HPIB HDD's?
Can their tapes be read on HPIB based tape drives?
If so then it may be possible to read/back them up using the HPIB / LIF
reader software I've been working on.
With the work that I've had to do on command formats I think that I may be
able to code a PC+HPIB card system that emulates CS80 or AMIGO based disk or
tape drives.
This would mean that the old HP system could boot from a PC emulating an
HPIB drive, removing ageing disk / tape drives from the loop.
Are these CS80 / AMIGO command set disks compatible with 80 series machines?
Joe: I have been trying to get hold of you -
How have you got on with the early version of the HPIB drive reader software
that I sent you? - does it catalog your drives OK?
I still need to get the postage cost on the 3 HP-UX manuals I won from you
on ebay so that I can close out that transaction. Let me know and I will
send you a cheque.
Cheers

Hi all,
I have in my hands a "Jupiter" computer and am wondering if you can
offer any info on it? It is not the Jupiter ACE home computer, but a much
earlier very large and obviously fairly old rack mounted system. The computer
is based on the 68010 CPU. I can't determine how much memory it has on board,
but there are more than several banks of 4164 mem chips which if I remember is
a 64kbit dynamic Ram device. The huge keyboard is attached via a missing
multipair cable and has two joysticks on either side. The monitor has separate
RGB and Sync cables, each of which are generated using separate discrete
component boards in the chassis. Inside the chassis are two huge Vertex hard
drives, and a 3.5 in floppy, each connected to their discrete driver boards,
Z80 based.
On the front of the computer is "Jupiter". Model number is J12CHAS and
Man date is "514". It was manufactured in Berkeley C.A. USA. The serial number
is "Jup.S.N. 12C-1025-AA". I basically found it all on a curbside and couldn't
resist adding it too my rather small but now growing collection. If you need
any further info to help with identification let me know, I'll see what I more
I can get from the chassis.
Maybe I'm insane and have just picked up what most would consider
total junk, but I personally think that systems such as this are worth
preserving. I haven't been brave enough to switch the damn thing on yet, with
all that discrete hardware it will probably double my power bill with about a
minutes use. However I love all this old stuff, and worse comes to worse at
least their are some interesting discrete components in it. If you need or
would like a photo let me know, I'm a freelance photographer and will take a
few shots anyway, so when I do I'll pass some scans on to you.

Does anyone remember if the Central Point Deluxe Option Board
can copy 1.4 MB 3.5" floppy disks?
I had one of these boards and gave it to a friend last year.
If it will handle 1.4 MB diskettes, I can probably get it back
and install it on some sort of old 386 motherboard system.
You wouldn't believe the old junk burried in my back bedroom!
Or, given this list ... maybe you would believe it. When I say
old junk, it includes stuff like some IBM 2321 Data Cell strips
and other things of that vintage.
:-)

Quoting from the manual:
* To copy high capacity, non-copy-protected disks (1.2 or 1.44 MB)
you must use the TCM program included on the Deluxe Option Board
software disk.
* The Deluxe Option Board is not capable of copying copy-protected,
high density disks. As these disks become more prevalent in the
market, we may include this capability.

I'm thinking what this means is that you can use TCM to copy 1.44MB
3.5" media, but there's no guarantee that it will reliably copy
media that are copy-protected.
