I found an odd looking board today that I THINK might be some kind of delay line memory. I'm trying to find out more about the ICs used on it but I'm not finding much. Can anyone id these ICs? MC1662L, MC1043P, MC1010P and MC1040P? They are all 14 pin DIPs expect for the 1662, it is a 16 pin DIP. All of them are dated 1973 to 1976. They are definitely not sync chips or PICS!
The board itself has seven glass or plastic cylinders about 3 1/2" long and 1/4" in diameter. Each cylinder is wound with a twisted pair of fine wires. Besides the beginning and ending points there are six additional taps in the windings. (A total of 8 connections per wire per cylinder). There are four 1662s next to each cylinder and the white wire of the pair is coupled to them. The red pair of the pair connects to a post that goes through the board. On the back of the the board is a daughter board that is seated on the posts. It has the 1040s, 1043 and 1010s on it. This board also has a row of four ICs for each cylinder. There are two 1043s and an two 1040s in each row and they apppear to connect to the posts that connect back to the red leads on the cylinders. The four 1010s are mounted on the bottom of the board between the rows of ICs and seem to be pre-drivers or some such. There's also a row of pre-drivers or something like that on the main board. They use MC1668L s and there are seven of them.
These boards came out of a LARGE test system built by Tektronix. (The same one that I pulled the DEC PDP-11/35 out of.) But someone else pulled these and I'm not sure what unit that came from. The main board and outside panel are marked "2941 Delay" and the daugherboard is marked "Delay Register".
Any ideas what these boards are? Can anyone positively id the ICs?

Hi Joe, Bill, Tony,
Sorry for the delay in replying - the 'proper' job takes precedence
unfortunately!
Joe - bit of a typo on my part the 9133 appears to be CS/80. Can you
explain the differences between CS/80 and SS/80? I seem to remember that CS
stands for Command Set and SS stands for Sub Set but other than my lack of
knowledge is complete.
I have an HP 1000 based system (the 5451c) that runs 7900 and 7906 drives -
are these CS/80 based too? It would be useful if I could back the software
up on these.
I think that the HP ISA card just allowed you to put DOS partitions on HPIB
disks not read partitions in other formats.
How can I tell if the drive is from an HP 9000 200 or an HP 9000 300 series
system? Do you still have your HP LIF foramt description document? - any
chance of a copy?
Bill - Thanks for clarifying the HP 88500A harware capabilities
Tony - thanks for the pointers with the LIF format.
I took your byte tables and overlaid them with the data blocks that I am
pulling off the disk and they agree very well (all of the record position /
record length values seem to be correct).
I have a few questions.
The volumme label / descriptor block, bytes 16-19, returns a directory
length of 1 but when I directory the disk I get around 280 filenames. A
directory of one block would only support 32 files - where am I going wrong?
In the tracks per surface, Number of surfaces, Records per track fields I
get all zeros - does this just mean that the drive does not report them?
What is the LIF file structure for text files?
Thanks for your replies
Cheers
Peter Brown

There are two common ways of specifying gears. One is by diametral
pitch (DP), where you specify, in effect, the distance between teeth
(actually it's done by dividing the number of teeth by the pitch
diameter). The other, mostly used for metric gears, is by "module",
and is the reciprocal of DP, ie you divide the pitch diameter by the
number of teeth. Gears that mesh will have the same DP (and, of course
the same module).
The trick is to find the pitch diameter -- that's the "effective"
diameter of the gear wheel. If you're using DP, for normal gears the
amount of the tooth above and below the pitch diameter, called the
addendum and dedendum, is standardised, and it conveniently works out
such that if you can accurately measure the outside diameter (OD), and
you can count the number of teeth (t), you can easily work out the DP
without actually measuring the pitch diameter directly:
OD = (t+2) / DP therefore DP = (t+2) / OD
and if you do need to know the pitch diameter, then since DP = t/p it's
just p = t/DP.
There's just one caveat: those formulae only apply to gears with a 20
degree pressure angle, and with more than 15 or so teeth (otherwise you
need to make some corrections as the angles get more extreme).

Hello all Can anyone direct me to some decent Classic computer software vendors or stores. I have found a few over the months that sold a lot of "New-old stock" which is interesting, but have been unable to find my "Agent USA" for IBM yet. (I used to own it). Maybe someone here has it? Brian

Go back to the hobby shop and flip through some RC magazines to locate gear

Last night I cleaned up the HP 1000 that I picked up a couple of days ago and double-checked everything. Then I powered it up. It came up with no problems. Next I punched in some code into the front panel and run it. I spent three hours or more changing the program around, moving it to different memory locations, running it with different data, etc. Everything is working perfectly. The two broken switches haven't been a problem. I just poke my finger into the hole in the panel and press the contacts. Now I have to get busy and built a terminal cable and hook up hard drive.

Hi All
I have a newbie question <collective groan from list>
I don't have much experience with HH type drives and recently unearthed
a Wyse Technologies machine at the local refuse recycling centre (it's
a shop rather than me wading though a landfill site - I'm not that
desperate).
Inside this machine (stated built in 1986) were two HH type 5.25" hard
drives (one a Segate ST-251 the other not branded but built 1989).
On boot up I get:
Pheonix 80386 ROM BIOS version 3.53
(c) 1985, 1986 Pheonix Technologies Ltd
640K Base 1408K Extended Memory
Hard Disk Failure
I have booted the system using a floppy and one drive (the unbranded
one) is partially readable.
It is a 41Mb drive split into two partitions (primary & extended) -
FAT16 system
It seems to have been installed with DRDOS.
Using my later versions of DOS on floppy I cannot get the drive to
respond to any standard commands (I always get a 'Sector not found'
error).
Can anything be done to revive these disks or were they left unparked
and now physically damaged?
I have another 5.25" hard drive displaying the same unresponsive
characteristics... are they all dead?
Thanks in advance
Alan
Does anyone have documentation for an 8086 assembler called IC86? There

OK now the light has finally come on. Thanks to all who provided
different pieces of the puzzle. I had assumed that the PDP-8
turned on the reader, read in however many words from the tape
reader it wanted, and then shut it off. It never occurred to me
that DEC would toggle this line on every character read, let alone
hard-wire this function, given the very slow speed of the tape
compared to even a PDP-8! I suppose I could have figured this out
by looking at the M706 schematic though...
So I'll put a relay in my ASR33 but I'm don't think I'll wire the
power switch connections, just the reader magnet path. I wouldn't
be using the 8/L and TTY without both being turned on anyway, and
only an SPST contact will be required.

I know this is a strange request for help, but I have done a lot of
searching for sources of odd sized floppy disks, and haven't had much luck.
The 8" disks are not so much a problem, but from what I can tell, there were
2.0, 2.5, 2.8, 3.0, 3.25, and 4.0 inch formats and finding even one example
has become a challenge for me. Since 3" disks were popular with the
Sinclair systems, these can be had off Ebay, but what of the rest? Its a
personal quest to one one copy of every type of removable media and if
anyone has any ideas, sources, information, it would be most appreciated. I
hope to post the collection to a website as I don't think it has been done.
Thanks for any input

Well if you have an HP9000 computer running HP-UX you can use dd to
get a copy of the disk image.

NetBSD (an Open Source Unix clone) supports the HP 9000 architecture
so the kernel source code (available from www.netbsd.org) contains
drives to access cs80 mass storage devices over HP-IB.

- "RSTS/E Device Requests" by Jeffrey L. Clark, "(11/79) W0-DEVICE".
19 pages.
I'm hoping to get time to scan the last two documents, which are
interesting to read, and possibly somewhat helpful to RSTS/E people.
Also, they don't have Copyrights on them, so I'll try to get them posted
to my website.
If anyone is interested in a copy of anything here, let me know off-list.

It's highly possible that the NVRAM's lithium battery will have
died ("gone flat") by now. This is the case with both the AV410
and AV4300 I have. My AV530s/5500 seem to be okay, but it's just
a matter of time before they face the same problem.
The machines with dead NVRAM will give some cryptic indication
of the problem like printing "IDPROM" and nothing else, and
refuse to initialize/boot on power-up.
'r. bear stricklin' was collecting NVRAM dumps for analysis, so
we can try to load usable data into replacement parts, but I've
no idea where that stands. I haven't bothered getting a part to
see if, like Suns, the machine will function at all with an
uninitialized NVRAM. Anyway if you search the archive for his
name or Aviion I'm sure you'll find the relevant post. Or head
to this URL: http://www.bears.org/~red/museum/aviion-nvram.html
The 88k Aviions were frequently SMP capable, though unless you've
got rackmount or square/big deskside units they're probably just
2-way. If you think the daughter card on yours is a second CPU
complex, look for a chip marked 88100 or 88110; those are the
CPUs. The 88200's or 88410 are cache/MMU chips.
DG/UX will support SMP out of the box. It's a decent enough SVR4
implementation, with X11 (R?) and some sort of logical volume
system. If you're looking for media I may be able to help out,
contact me directly/off-list (smj0302 _ crash _ com).

There's been sporadic interest in getting *BSD running on the

hardly seem "classic" to me, since when I started collecting computers
these items were brand new, but they *do* meet the 10-year definition!
