This died out, Do we want to do our own Wiki?
The last suggestion was that we make entries at WikiPedia [
http://en.wikipedia.org/ ]
I think we would be better served with our own Wiki, we would be able
to arrange the
data in a way that would mean something to us. Otherwise would have to
have our machines
peppered about in between other subjects.
I suggest this arrangement:
Introduction Year : Manufacturer : Model : User : Individual machine
Some Wiki's also allow for a user's home page. There I sugest each user
tell us about
their collection / machine (with a link to the machine page)
A few minutes ago, I got my PDP-11/73 to boot. I installed the disk
controller and connected the hard drive. I typed in the boot program,
and booted from the BRU standalone tape. It worked! This time it didn't
crash, since it could find the drive controller. It booted up and
displayed this: http://24.194.65.231/images/screen1.jpg I haven't
figured out how to get past this though. Typing /dev gives me this :
http://24.194.65.231/images/screen2.jpg I tried typing in a device
name, but it just gives me a syntax error. Hardware wise, I think that
everything is working together properly. I don't know how to use the
software though... To start off with, I'd like to run a flavor of UNIX
on this, since I know UNIX very well. Any reccomendations as to what I
should use? BSD 2.11 should work on this, but I don't know how well. In
the future though, I'll probably install a PDP specific operating
system, like RSX or RT11, and learn that, but at least as I get things
going with the hardware, I think I should at least stick to software I
know :). Also, once I do get something installed on the hard drive, how
do I boot it? Currently, toggling the boot switch doesn't boot the
machine. Should it? Will I have to type in a bootstrap code every time,
or can I make a ROM do it for me?
Here are some more pictures I took of my current setup.
This is what the computer looks like at the moment. The side panels are
off the rack, and the cables are just hanging around the front for the
time being as I am just testing at this point. I'll neatly route them
out the back later. I'm currently using a Lear Siegler ADM3A, since it
was convenient when I was first hooking it up. Not only that, but I
really like the ADM3. Mine's missing two keys, but it works.

This is one of the brackets I had to make to mount the Fujitsu Eagle
into the rack. It's made out of a Home Depot bracket that originally
was wider, and had two little wings coming off the top of it. I think
it was intended to join two 2x4's together somehow. I cut it down with
a Dremel tool, and drilled new holes in it. It worked out very well.

HP recommends cleaning the heads on the 14" drives with a flat wand, and a
cleaning sleeve that fits over it.
--
Tex-wipe made them
They're called Tex-Sleeves and are a blue plastic split wands that
look like oversided tongue depressors (1" x 6") with a lint free
cloth sleeve that slides over that like a sock.
The ones I have are in storage, will retreive the part numbers for
you.
I have extras of the plastic parts, but am running out of sleeves.
This is exactly the right thing for cleaning 2315/5440 style upper/lower
heads.
Here's another one. Why does this seem familiar? Didn't I already post
this to the list? Or did someone else? At any rate, it just plunked into
the hopper so I'm passing it along.
An IBM 5362 in England. The address makes no sense to me: I think this is
an estate sale company in four locations(?) North Leaze Farm, North
Cadbury, Yeovil, Somerset. Take your pick. Sorry, my geography of the UK
does not enable me to figure out where this is exactly. Or maybe it IS
the address (quite odd by US standards at least). Or maybe it doesn't
make sense anyway.
Whatever.
There's also a Kienzle 2000 "magnetic card accounting computer" which
sounds rather cool.

For those of you who may have wondered where I'd gone, I really didn't
fall off the face of the Earth (and contrary to what some folks might
believe, the Earth still isn't flat).
I'm currently recovering from a multi-drive failure in my RAID-5 array. I
was very, very lucky in that only one of the drives died a horrible death,
with the 2nd having a semi-recoverable error. The second drive failed
before the array could reconstruct itself, and my spare drive was already
in use. Had I been running an OS where I didn't have the source, I
probably would have lost all of my data (roughly 25-30GB currently), but
since I had the source to the RAID software, I think I've managed to
recover most everything. Let this be a warning to anyone else with a nice
RAID setup who also doesn't keep current backups... My DAT drive died
about 6 months ago, and Sony can't seem to cough up a service manual.
[If anyone has any surplus DLTtape IIIXT tapes sitting around collecting
dust, feel free to contact me off-list. I managed to collect a DLT2000
drive right before my DAT drive died that still hasn't attracted the
proper tapes. I'd also like to find an inexpensive source for new or low
mileage 4/9/18GB UW SCSI drives, as I think it may be best for me to
replace the entire lot of old 9GB drives that made up my RAID-5 array.]
I also have a number of things that still need to get sent out to folks.
If anyone is expecting anything from me and doesn't hear from me soon,
contact me off-list and remind me.

OK, mine concerns a PDP-11/40. When I got it, it wasn't in a rack,
just lying on the floor, minus the power supply, a few wires cut, a bit
of rust here and there, and no docs. At the time I didn't have a
Unibus machine with a full lights-and-switches front panel, so I took
it anyway. After 2 or 3 years of lying on *my* floor, I gave up trying
to get a power supply sorted out, and gave it away to someone whom I
suspect broke it up. The sad thing is that it had a full complement of
boards in the CPU (my present 11/40 has no FPU, no MMU, etc) and a few
extra goodies. Moreover, it turns out to have been been one used for
the developmenmt of MUMPS, so it was actually a more historic machine
than many.

HP recommends cleaning the heads on the 14" drives with a flat wand, and a
cleaning sleeve that fits over it. They also recommend the same device for
cleaning the fixed platter, through an access port next to the heads. I seem
to recall that old Microdata Reflex drives I used to work on wanted the same
thing. You put the sleeve on the flat wand (the wand is much like a tongue
depressor in shape, but a bit longer, and plastic), dampen with ISO 91, rest
it on the platter through the access port, and slowly turn the hub by hand.
I have searched the net, and can't seem to find a source for these wands and
cleaning sleeves anywhere. I would have thought they'd still be around. Does
anyone have a source for these?

they'd probably recycle it into scrap so as to not risk offending

I've just acquired a MLSI-DB11 (produced by MDB), which is a QBUS
adaptor that sort-of looks like an SMD disk controller. I'm not quite
sure if it's that, or something else. The closest thing I've found to
what it is the DEC DB11-H adaptor, which I can't find any description
of anywhere.
The MDB card is a dual-height QBUS card with a 60-ish pin connector, 20
pin connector, and 2 smaller 10 pin headers on it (might be off by a
couple pins on those counts).
Does anyone know 1) what this is and 2) anything about it?
Thanks,

I went scrounging a couple of days ago and found a big box of DC 30
tapes. Is anyone familar with these? Or know of any systems that use them?
I THINK these came from a computerized component tester made by Seimens.
They look like audio cassette tapes but are slightly larger. These tapes
are made entirely of plastic and don't have the metal plate on one side
like the DC 300 tapes, HP-85 tapes or DEC Compactapes. I think the Seimens
component tester may be a rebadged tester make by Analog Devices. At the
same place I found a big pile of Analog Devices plug-ins to mount and
connect various types of ICs and other solid state devices but I didn't
take the time to see if they fit the Siemens marked testers.

Was this is response to the thread a couple of months ago?
Paper tape is still available from several suppliers, though only a few
companies still actually make it. However, not all modern "oiled" tape
uses resin -- some manufacturers do still use oil, according to the
company in the UK who are getting me some (from Germany). Resin is an
effective barrier, but worse than useless as a lubricant.

That's probably 3.6x. Sadly, Frank da Cruz no longer keeps older
versions of Kermit online (something I regret, as periodically I need
to find yet another version for some newly-acquired machine, and also
because I dislike the bloat that happened between C-Kermit 5 and 6).
Luckily there are other places to find it.
Thanks to Tim Shoppa, several DECUS tapes are available which have
versions of Kermit-11. It's usually in account (directory) [356,040]
on the tapes which included it. Look for the file k11ins.rno (or
k11ins.doc, which is a flat ASCII file but most servers wrongly assign
a MIME type of application/msword to it, just because of the suffix)
for release notes. .rno is a RUNOFF file, the source for a document
processing system akin to (but much older than) troff.
3.51 (Spring 1986) runs under 7.2 but doesn't handle binary files
properly, and only builds under 8.0 or later. It's at
http://www.ibiblio.org/pub/academic/computer-science/history/pdp-11/rsx
/decus/rsx86a/356040/
2.30 (June 1985) says:
"This is release 2.30 of Kermit-11. It requires RSTS version 7.2

RSX11M Plus version 2.0 or later, or RT11 version 4.0 or later.
Minimum system requirements to assemble and link Kermit
RSTS v8.0 or later, with multiple private delimiters and RMS V2
Kermit-11 will run on RSX11M version 4.0 and RSTS/E version 7.2
as long as the task was built without using RMSRES. To be able
to build KERMIT on RSTS version 7.2 or RSX version 4.0 you will
have to get RMSLIB.OLB and MAC.TSK from RSX v4.1 or RSTS v8.0."
It's at
http://www.ibiblio.org/pub/academic/computer-science/history/pdp-11/rsx
/decus/rsx84a/356040/
Most of these have pre-built binaries in the form of .hex files; these
are flat-ASCII hex representations of the binary, intended to be
stuffed over a serial line by a simple terminal emulator or whatever,
in case you don't already have Kermit or something similar to transfer
a binary.
There are also de-hexifier programs in various forms (BASIC, FORTRAN,
C, etc).
Most of those directories also include other verisons of Kermit (ie,
not for DEC OSs). I discovered that last URL I gave has C-Kermit 4C
:-)

I mentioned this before, but the subject line may not have caught the right
people's attention. I need access to an ASR TTY with the reader-run mod to
do some final testing on some cards I am developing for myself and the
group. If you have a pdp-8i or pdp-8L that's great, otherwise I can bring
my 8L. I am in the Portland (PDX) metro area (Beaverton, actually).
The cards have already been tested with a TTY which does not have the
reader-run feature, so it is that specific feature I still need to test.
Anyone out there who can help?
Thanks!

Newer paper tape is not oil impregated at all but has a barrier / lubricant made from resins. Tape is still available from The Trybus Company in Pittsburgh. (412 367-1880) They also carry Mylar tape which I prefer.
Quite often a customer will come to me with an old worn out executive tape and ask me to "do Something". I will generally read in the tape using a DSI reader that I have slowed down to 30 CPS and have narrowed the strobe width to 1/6 the charactor width. I will then use a FACIT 4070 to generate a new tape onto Green/Gold mylar. On executive tape using all 8 bits and no parity I use norton disk edit to make any manual repairs. This eliminates the need to splice fragile originals.

Last week I got the system unit and the tape drive mounted in the rack,
and yesterday, I managed to mount the Fujitsu Eagle. Now I'm trying to
figure out how to hook it all up...
I have been tinkering with it this morning, and finally, about a half
hour ago, I was able to see some activity. I found the information on
the serial board in a handbook, set the terminal for the proper baud
rate, etc, and connected it to channel 3 of the card. Powering it up
gives me the @ prompt. So far, the only things in the machine are the
CPU, the serial card, a 1mb memory board, and an Emulex tape
controller. Now that I have gotten it to do something, I'm totally
lost. I've never worked on a machine like this before. I don't even
know how to type in the boot program. I have a tape boot program here,
on a piece of paper, but I don't know how to type in the values. I've
tried all sorts of commands, all of which yield a ?. Typing P seems to
step the processor through something, as it prints 000002, and then
typing P again increments that value. G prints 177777, and the LED on
the tape controller lights briefly. Same thing if I toggle the boot
switch. I tried loading a tape into the drive and putting it online,
but I get no drive activity when I toggle the boot switch.
So, can anyone offer hints or suggestions as to what I should do next?
I'm lost...

OfficeConnect hubs, switches, whatnots, are very small devices that
have an external wall-wart PSU and no fan, and are normally absolutely
silent.

Thanks, Al, for the microcode rom dumps (however the 12823-80020.bin, F-SIS
is missing - lost somehow during copying?).
--
It should be there now
I've seen that the base ROMs slightly differ from the microcode listing in
the 2109-90004_1000EF_uPrgRef_Apr80.pdf from your site. What is the
relation between both sets?
--
The set that is up there was the last released set, and uses x8 proms instead
of x4. Release histories of the firmware can be found starting on page 33-1
of the CE manual.
I've hacked together a simple microcode disassembler for these ROMs, with the
exception of the 1816-* ROMs that I do not know how to handle (any further info?).
--
That is the MX IOP firmware. They are x4 parts (256x4, 82S129's to be exact)
I suspect Bob Supnik or Mike Gemeny may already have disassemblies of that.

Nope. Nothing at all that *ought* to make a noise :-)

Ok, how about one of those little beeper/speakers? Does
it have one of those? Otherwise, it is most likely an
electrolytic.

Yep, as I recall it was the limit of the ADT (Available Disk Table). I want
to say that the ADT was swapped in and out of core on a per-drive-basis as
needed. But the core allocated was only big enough to hold 32MEG worth of
available disk bits (per drive).
So, 3*5=15, 15+32=47
I?m just going on memory on all of this, and that?s been 20 years ago now.
Feel free to chime in here if my memory is not serving well enough.

I took a look at Paia's website, but it wasn't listed in the archives. You might want to go to www.paia.com and look for a phone number or email link. They like to hear from people with old Paia gear, and I'm sure there's someone there who will be able to tell you what it is.

ORIGINAL MESSAGE FOLLOWS:
I acquired a PAIA PVI-1 circuit board yesterday, and a Google search
brings up no information about this board. The main chip seems to be a
GI 2513 with some 8 7400 and CMOS support chips. On the circuit board
are two RCA jacks labeled TV and VID, two pots labeled "H POS V", a
jumper for selecting 32 or 64, and another YES or NO jumper for the
cursor. The code date on some of the chips are in the 1977 era. Does
anyone know what this thing is, and does anyone have any docs?
In the haul I picked up last week, one of the advertised VT-100s turned

Can someone point me at the requirements for running a version of RT-11
(like v4 or v5.3, v5.4) on a PDP-11/20. I'm pretty sure I can
get enough memory (in a BA11-K expansion chassis) but I want to know if
there are other "gotchas" (like having an EAE).
Also does anyone know where there is a reasonable copy of DOS/BATCH? I
tried an RK05 image that's around on the 'net on one of the simulators
and had little success. Did any version support RX01's?
Thanks.

I just recieved a few DECmate III "motherboards" which are supposedly
functional (the guy is selling more of them on eBay right now, for
their Intersil 6120 chips). Before I attempt to desolder the chip,
does anyone have information on these things? I'm looking for
information on what each of the connectors is, and the pinout of the
power connector (J2) and kb/video connector (J5?). Also, any manuals
or images of software disks for this thing would be nice : ).
Here's what the connectors are labelled on my board:
J1 and J? (can't see a label for that one) are 34pin headers, and I'm
guessing go to RX50s, J3 is probably the 'expansion connector', J6 and
J4 are serial(?) and J5 is the video/kb (?). I'm fairly certain that
J2 is power, but don't know what its pinout is without playing with my
DMM... but I'd rather get it right the first time and *not* smoke the
board...
Btw, J? hangs off of the side of the board, and is a right-angle header,
unlike all the rest of the connectors.

<snip>... similar light dawns over marblehead...
I was just realizing that I gave away probably my only installed copy of
the RX50.DRV shim the other month... This was an MS-DOS device driver that
remapped the standard HD 5.25" drive to be Rainbow RX50 compatible.
Does anyone have this or something like this that works with current MS-DOS?
(or even old DOS versions, I could boot an old version to just copy files)
I have a bunch of RX50s lying around I should look at before disposing of...
Dave (former Mr. DECnet-DOS).
I've got this 3Com OfficeConnect Dual Speed Hub 8 that is putting out this
obnoxious hissing noise. It's loud enough to be annoying and add
significantly to the white noise in my office. It sounds like the air is
slowly being let out of a tire...forever. I've opened it up and found a
capacitor with some brownish crusty stuff caked on the top of it. It also
was bulged ever so slight at the top, as was another one right by it.
Both are within proximity of the power connector. I didn't see any
blackened spots on the enclosure indiciating that either had let out any
magic smoke.
So the question is, what is the most likely cause for this hissing? I've
had a device before where the capacitor was causing the hiss (or at least
I was pretty sure). There doesn't seem to be anything else in there that
would cause the hissing (a bunch of ICs, a couple couls, a couple power
transistors, etc.)
Any help appreciated.

ChromTech still stocks paper for the HP85 - their part number CTP-3390.
Price was $22.25 a roll which should last a _long_ time. Website at
www.chromtech.com . Sure makes a difference to use the fresh stuff!

Certainly not an oxymoron. I have a real soft spot for analog
computers. The theorist in me wants to hear the term analog
computer as a whole as describing a computing device in a different
class from the sort we've been discussing. A part of me kind
of wishes a different term had been adopted for these machines,
but differential equation engine just doesn't have the same ring.
Now if I had just had a way to rescue the EIA hybrid machine I
used in college. Of course, I'd have no place to put it, but
we can ignore minor details like that...

Hi Ran,
I just wanted to follow up and ask you if you still have a Currah
Speech Messenger cart for the C-64 left. I've been looking for one on
eBay and I never seem to be able to get my hands on one. Please let me
know if you have one available or not, and if you do, I can send
payment via PayPal. Thank you for your time!
Sincerely,
Tony
