Hi, All I'm back at the grind trying to find a few old OS's The first is for
my TEK DPO (WP 1210 Digital processing
scope ) this is a 7704a scope with a P7001 Digital
processor that connects to a DEC PDP 11/05 . It runs on
TEK Basic (8" floppy or DEC tape}.. The official name is "TEK SPS Basic V02"
There is also a system test
disk. This uses a TEK 4010 Terminal for a display.
The second is a Pertec Mini ?? coax system 4010
Don't know much about it other than it used coax to the
dumb terminals instead of Serial.. (1/4 " Tape) The third is a OMS Zues 4
I beleive it ran cpm or mpm
(5 1/4 disk) The forth is a Tek 4051. looking for the Tape images.
The fifth is a Tek 4404 computer. Looking for the disks
(5 1/4 floppy)
I can handle most image files. Or would gladly pay for
a Disk or tape. If I missed somewhere online, point me
in the right direction Thanks, for reading this Jerry Jerry Wright JLC inc

Before I put it on the auction site.
I've for sale a HP-85 with a QIC40/80 modified tape drive including:
ROM drawer with :
1 Matrix ROM
1 Mass Storage ROM
1 Input/Output ROM
1 Printer/Plotter ROM
1 Advance programming ROM
16 K RAM module
HP-IB module
HP 9121 double 3.5 disc drive
2 QIC40/80 tapes (1 empty, 1 containing the Standard software)
2 3.5 inch disc's (NOS)
1 Carrying box (brown skai)
If necessary a complete manual set on CD/DVD
It is a complete set for who wants to start with the HP-85.
I acquired the HP-85 a few weeks ago checked it and converted the tape drive
to QIC40/80 replaced the printer timing belts and some elco's.
The computer is clean but a bit yellowed, the HP 9121 drive is cleaned and
all hardened grease is removed so it is fully functional.
I'm open for offers, the items are located in the Netherlands but I ship
worldwide, local pickup is also possible.
I'm not doing this to get big money but I want to earn a little to acquire
other HP-stuff for my collection and find it fun to restore old HP
equipment.

Hi all,
It is probably asked before, but I can't seem to find it in the archives.
I have a MicroPDP up & running 2.11BSD but no spare TK50 tapes to make
a backup of it, before I f*ck it all up :)
I do have a lot of TK50s which weren't mine and they have data on it
of which I do not know the status. They came with a MV3100 with VMS on
it, which I am going to use eventually as well. So I'm not really
willing to just scrap the data on those tapes. I'd like to make a
backup-image of those across the LAN before I write anything else on
it.
How do you guys usually do it?
# tcopy /dev/rmt0
to see what's on it
# dd if=/dev/rmt0 bs=??? | rsh
other_current_bsdmachine_with_lots_of_diskspace -l <user> dd
of=vms_tape_file?.img bs=???
for every file on there?
I didn't even know `dd' wouldn't cross EOF boundaries tbh (wasted my
youth on C64s and Amigas :)).

Hi all,
The reason why I'm interested in this topic is that I recently restored a
Ferguson Bigboard I with its CP/M 60K.
I'd like to try different programs that are contained in third parts
diskettes, but they are of course in a different formats.
I am using ANADISK to identify the format and sequence of sectors on disks
and 22disk133 to try to read them correctly.
Despite having read the definitions of the FCB manual on CP / M, I am
finding difficulty in :
1) to determine the block size chosen for different disks;
2) Identify the value AL0
Unfortunately it seems that any further calculation is dependent on the size
of the block that would seem a prior undetectable, and i'd need to try
different values (starting from 1024,2048,4096 and 8192). Is it in this way?
Some format i'd like to determinate:
A xerox SWP diskette: SSDD 9,1024 sectors sequence 1,2,3,4,5,6,7,8,9
A MK-83 diskette: DSDD 8,1024 sectors sequence 1,4,7,2,5,8,3,6
Thanks for any helpful hint.

It took me a lot of work to discover this information, and I am not sure
why it's so cryptic. But anyway...
Some time ago I mentioned I had a Tandata TD1100 viewdata set on the
bench. At power-on you get a dialing menu, the numbers for which are
clearly stored in the battery-backed RAM. Dialing a number from the menu
was easy (<menu number>#, for example 2#). But I could not find out how
to stroe numbers in the menu, everything I tried got 'Please Try Again'.
I am not suprised I didn't find the right sequesnce by trial and error.
It is clearly designed to be impossible to get by accident. I fianlly
found it by readign otu the firmware ROM (it is socketed, but I can
assure you that desolderign a 24 pin DIL chip would have been trivial
compared to the rest of it), writing a quick-and-dirty disassmbler for
6502 code (soemthing that took me most of yesterday (Newtonsday)
afternoon [1]), and then going through the lisitng.
[1] This would ahev been a lot easier if the 6502 data sheet I'd been
workign from handn't been written by a boatie. There's a nice 16*16 table
of the nmemonics, the rows and columns being numbered from 0-F. It turns
out that the _rows_ are the most significant nybble, in other words you
read it across, not down. The lables indicating this are in tiny type in
one corner, and I missed them. So I had to move my table of mnemonics
aroudn a bit. ARGH!
My first guess, which turned out to be correct, is that it would use CMP
instructions to identify wheter a typed character was 'acceptable' or
not. So I searched the listing for these, and found a sequence of CMPs
which seemed to do the right thing. I then spent some time figuring out
what that routine does, and I finally got the sequence to load a number
into the dialer menu. It is :
Turn on 'program mode' with the switch on the back first and type :
<menu position>*****<Number to dial>#
For exxaple 2*****123456# will store 123456 into the second position of
the menu. Note that it's 5 '*'s. No fewer (or you get an error), no more
(or you get spaces at the start of the number in the menu.
If you do not turn on program mode, the entry is ignroed -- no error
message.

I had this years ago and found only the manuals in my archives. Does
anyone have the diskettes or images for this program?
I found an MS-DOS version on the web, but turned up nothing for CP/M.

Hope you all had a merry christmas with and santa bought nice things?
Guys Im searching for the schematics of the russian I12 (MC4601) Interface
board for their metric PDP11 Q-Bus machines.
This card is something like an MXV11 w/o the memory, just 2 SLUs on this board.
I have such a board here that must be repaired and I want to look to the
schematics to steel parts of them for my K1801VM2 SBC...
Can someone help please?
I konw, that the shematics where postet on the russian narod.ru site but
the link is dead now...
Kind Regards,
Holm

Planes use 400 Hz. US Navy ships seem to use 450 and 120V 400 Hz for
electronics and weapons systems and servicing aircraft. Presumably any
other country's aircraft carriers also provide 400Hz power for the aircraft.
