Alison is probably correct. Some DEC drives do have a jumper to select
spinup on power-up, but the RZ23/24/25 definitely don't (the original
Connor drives do, but DEC changed the firmware) and some notes I have here
suggest the RZ55/56 have different firmware too.
What you'll get out of the drive depends on what the OS is trying to do: a
SCSI MODE SENSE command will work fine, but you won't be able to do
anything more interesting until the disk has spun up (which is done by
issuing a START UNIT command). DEC used to have a utility called RZSPINUP
to do this, but any SCSI utility that can issue a START UNIT command would
do as well.

hmm, i didn't mention paper tape. I have printouts
of a bunch of programs from the HP2000F system from
my high school days. mostly thermal paper stuff.
To the few who have requested it, I will dig the

Yeah, sure, folks have been doing this for about a decade and a half.
See, in particular,
ftp://ftp.spc.edu/third-party-disks.txt
At a minimum, before getting any further, you're going to need some
way to format arbitrary MFM drives to what the DEC controllers will
expect for a low-level format, either a VS2000 with its built-in
console formatter, or one of the DEC XXDP formatters (ZRQB for the
RQDX2, ZRQC for the RQDX3) and a PDP-11 to run them on.

My TK50 User Guide (EK-OTK50-UG-004) shows them in both TK50-D standalone
(horizontal) and BA23 (vertical, on their left side if it makes a
difference) cabinets. My DEC-original MicroVAX in a BA23 has a TK50 on its

I'm not sure exactly what Tony is talking about, but it is indeed true
that in some contexts (musical instrument repair, in particular) "silver
soldering" refers to brazing with a bronze alloy - there's no actual silver
involved at all.
"Silver soldering" can refer to a half-dozen other processes, as well...
(most of them admittedly involving at least some silver!)

Allison,or Anyone
I recently got my MicroVAX I up and running it's MicroVMS 4.1
I listed devices and have an RD52 as DUA0.
and an RX50 as DUA1 and DUA2
I did not see any directory commands to tell how much disk space is
used/available. Are there any?
Nor did I see any FORMAT command. (Which at this point I want to AVOID,
because I don't understand the Backup process or target backup media
capacity constraints. It sounds like backup clones the OS on the same drive
in "renewed" and/or "rebuilt" files )
According to Allison's prior post, should I assume this RD52 is a 30MB MFM
non SCSI drive?
I also have a Plessy 6600/6700 system which has a 84MB-90MB drive which I
think hangs on a DEC compatible SCSI controller.
(I believe the Plessy is an LSI-11/34 clone.)The Plessy also has a Cipher
F880 1600 bpi 9-track tape drive connected.
Is there a chance I could Load the Hobby openVMS on either one, or both of
these systems in a cluster?
It seems to me the more capable system would be the Plessy with larger HD
and Tape Unit already installed, (However I have never booted it, and I
have no Idea what OS currently resides on it.)
I believe someone gave an earlier response that the MicroVAX I was too
small to run openVMS alone.

I am trying to install NetBSD on my MicroVAX 3100. I would like to
install it on the RZ56 which is in its own expansion box. The problem,
or so I am told, is that the drive as it is needs to be told to spin up
and NetBSD doesn't do that.
It has been suggested that there might be a jumper to tell it to spin up
automatically. Does anyone here know if that is the case, and if so,
where it is?

Pete
My Point would be that the ABSENCE of option jumpers on pin headers usually
defaulted to immediate start.
If you see an option jumper on the RZ56 other than SCSI ID. Would it hurt
to pull it?

Hmm. I didn't have any luck with the RZ56 and the MicroVAX 3100. I never
had any time to track it down.
As a first attempt to see if it will work at all, you can do a
SHOW DEV at the >>> prompt to get the console to spin up all the
disks. It's been my experience that NetBSD hangs while trying to
probe the SCSI bus if there's an RZ56 on the SCSI bus.
I'm not aware of a jumper that makes the RZ56 spin up, but there is a
setting in one of the mode pages. There was a program under Ultrix called
rzdisk that allowed you to, among other things, tell the drives to spin
up at power on. I think there was a similar program for Alpha/VMS as well.
Roger Ivie
ivie(a)cc.usu.edu
I know nothing of the RZ56, BUT several seagate drives had jumpers for Motor
Start and Delay Motor Start.
In Seagate terminology if the Motor Start jumper was connected then the
Drive Waited for the SCSI "Start Unit" command to start the drive. IF the
Motor Start Jumper was NOT CONNECTED the drive fell through to a delay motor
start scheme. If the Delay Motor Start jumper was MISSING,-the delay was
disabled. If the Delay Motor start jumper was installed the drive multiplyed
the SCSI ID by 10 seconds and spun up the spindle. So ID 2 would spin up in
20 sec. ID 3 would Spin up in 30 sec. etc. I assume ID 0 would start
immediately on power up.
I had also seen some IBM SCSI drives that had a motor start jumper termed
"start on command", otherwise they powered up immediately.
But then again those were Seagate and IBM schemes, I can't speak to DEC
RZ56..

I don't know about jumpers, but if you do a SHOW DEV from the console

Darn! How could I forget. I collect LPs (long playing records). I also
collect 78 rpm records, which I play on a wind-up gramophone, but I don't
collect many, because I seldom find any with music that I like (= mostly 20th

recording on LP.
I have some 8-track tapes, but I passed up the only player I ever saw and have

as much as I could carry home. I hadn't brought the car)

Nice. It's not long since my parents got rid of the huge LEC refrigerator that
they acquired secondhand in 1973 [*]. Nice beast, but the door latch was broken
and would have needed a custom casting to repair. We held it shut with bungee
straps for years. Can't remember what finally killed it. Goodness knows what
date it was, but I'd guess 1950s.

Yes, yes, no; see below...

That's not *exactly* true; the solidus point (the temperature at which it
begins to melt) remains almost exactly the same, but the liquidus point
rises. In between, though, the solder is rather pasty. That's great for
old-fashioned plumbing, but it's apt to produce dry joints in electronics,
so for practical purposes, the useful temperature rises just as Marvin
says.
For example, 40/60 solder has a liquidus point of 227C (440F) and 60/40 has
a liquidus point of 188C (370F). Adding certain other metals, especially
bismuth, lowers the melting point, though many other additives, such as
antimony, raise it. According to my Multicore Solder list, the recommended
bit temperature for 40/60 general-purpose electronics solder is 354C
(670F), and for 60/40 it's 308C (585F). Personally, I'm never that
precise; I just twist the setscrew on my Oryx TC irons until they work
right!
"Silver solder" comes in a variety of grades, the ones with the lowest
melting points are ArgoSwift and EasyFlo2 which melt at 600-610C
(1100-1130F, that's a dull red heat). EasyFlo2 is 42% silver, 17% copper,
16% zinc, and 25% cadmium. Most engineering silver solders are
silver+brass based like this. A few are silver-bronze (bronze being an
alloy of copper and tin).
The "silver-loaded" solder Tony and others mentioned is a soft solder
containing 62% tin, 36% lead, and 2% silver. It has a melting point of
179C (354F) and a recommended bit temperature of 300-310C (570-590F).
Other silver/tin/lead solders like Comsol (I bet Tony has come across that)
and LM5 are high-melting point soft solders, with a high lead content.
I've seen them used for fusible resistors and the like.
I expect this is at least four times as much as most of you ever wanted to
know about that silvery-grey stuff that holds the components on...

I just hope I can pull aside as many good minis from the '60s as I can. This
company does not stop cutting for anything. I had no idea so many IBM 30
series? systems get chopped up every week. The 1130 and the 8 bit front

exercise wil yield some good parts and systems needed. He does get in quite
a bit of documentation with the systems and I will be taking as much of that
as I can. He has a *huge* DEC load coming in next Wednesday so I will be
there on Thursday. I have scrapped quite a few systems my self (and thought
that was bad) but seeing what his site does in one day made me sick.

Not that bad, surely. It's not as if I don't use it!
Anyway, no need to worry. This gong was never in a gamelan, AFAICT. And I have
a saron or two to keep it company (although it turns out the saron is tuned in
slendro, and the gong in pelog. Oh well. I searched for ages to try and find a
melodic instrument tuned in pelog, and failed - and never even checked the gong)
For anyone who goes to Jakarta: the antique market in the Jalan Surabaya is
unmissable as a place to visit, but most of the stuff on sale is far from
genuine. The gong is detectably a fake [*] when you look at it, but I chose it
on listening, not looking. The stand is a blatant fake - a combination of two
incompatible ethnic styles - and judging by the newspaper used in construction,
dates from around January 1997 (I bought the gong in July or August that year)
Philip.
[*] made in several pieces with welded seams that are just visible. Real gongs
are beaten from a single sheet of bronze. For that matter, the notes on the
saron are pieces of bronze plate, bent into shape, when they should be
individually cast...

Thanks. We got it c. 1989 for VAXBI development. I got to write the firmware
and device driver for our intellegent serial card. I currently have a box in
the basement with 80% of the world's production of it - 8 cards out of 10.
After all the development, it was never a big seller due to the fact that the
world had moved on. At least we priced the card high enough to break even
on the production costs and the cost on the 8300, barely. If you've ever
wondered why VAXBI SCSI cards cost so much, it's because a) they can and b)
nobody ever sold more than a handful of anything for the VAXBI except DEC.

I need a DASD for IBM 5363, which uses the IBM 0669 ESDI disk. This is
the same type no. as the 115MB used in the IBM 8580 PS/2, but with a
different feature code, and the block size switch set to 512 bytes,
instead of 256 bytes.
I've installed the 8580 variant in the 5363, with switches on the disk
set per the IBM 5363 MIM specs, but the init routine pops an SRC
indicating that the defect map is missing or damaged and refuses to LLF
the disk. I suspect this is due to the fact that the factory defect map
was written with 256 char. blocks instead of 512 char. blocks, but I'm
not sure--and I don't trust the IBM error codes since they aren't
exclusive.
The only variable I haven't eliminated is the drive electronics. Before
I spend time swapping drive boards, I wanted to consult with other folks
who are prone to commit such foolishness and see if anyone had any
wisdom to share.
If the drive boards don't make any difference, my next project is an
attempt to hack the ROM on the 8580's ESDI controller to see if I can
make it work with 512 char. blocks, then try to re-write the defect map.

Aha! Another VAXBI survivor! The company I used to work for did a quad
IEEE-488 interface and a MIL-STD-1553 interface. I did the firmware for
the IEEE-488 interface (imaging a Z80 looking up user-space addresses
in the page table. Fun!) and the device drivers for both interfaces. We
did hardware debug by running CP/M on one of the IEEE-488 cards; that's
right, I have a VAXBI machine that runs CP/M.

We sold about a hundred or so IEEE-488 interfaces. It took many years, but
it did manage to climb out of the red ink. The problem is that the bloody
thing simply will not die; I've been averaging about one inquiry a quarter
on it.

Hey, I'd not spotted that. Yes, gamelan music is very binary: although the very
slowest pulse (marked by the gong ageng) may not be a binary multiple of the
next one up (gong suwukan, which is what I think I have), all the others are
indeed binary subdivisions. One characteristic of gamelan music is that it
tends to subdivide so far, and slow down so much, that I lose track of the tune
in irama wilet or anything slower (I can't remember the names of half of these,
it's so long ago)
Something I never managed on either trip to Jakarta was to watch a wayang show.
Oh well.

I don't know any Japanese so I can't comment. But German has a tendency to a
verb on the stack, rather than say it, and leave it there until you've what the

When my contract ran out in April, they were still a couple of projects
running on the cluster of an 8550 (now defunct and a source of parts), an 8700,
an 8810 and some model of 7000. There were numerous 8650s and 88xxs and many
stripped shells of 6xxxs earlier this year. As I've written before, no chance
of rescue. :-( The VAXen, at least, being as big as they are and that
particular data center being as lightly used as it is, they haven't bothered
to clear out the machines. It's easier to leave them where they sit than to
move them. Perhaps they'll clean house in the New Year. Oh... I almost forgot
about the pair of RP06 drives sitting in the middle of the room with nothing
to talk to. There is *nothing* anywhere in there that could *possibly* have
a MASSBUS. I suppose that, given the large space _near_ the RPs that there
was once a 785 or something similar but has been gone for years.

I should be more precise - I was referring to the Columbus Works, not
anyplace on the East Coast. I would be seriously surprised if you ever
installed a system in Ohio.
My primary job there was to be "The Sun Guy". Everybody else was an NCR
expert. They still have lots of them there, but NCR is just down the road
in Dayton.

Really, in my opinion; its not _extremely_ bad just for some basic poking
around in VMS (which is all I can really do with such a minimal install
anyways :) I once had a 386SX-16 running like Slackware Linux 3.5 as a
NAT gateway on my LAN with 4 megs of RAM... after that, pretty much
anything else seems fast (considering it pretty much ran from swap :)
I'd like to get some more RAM for it.. originally, it had a 6 meg
expansion board, but it turned out to be bad so I removed it.. I'd
like to get the system expanded to something a bit more usable, but
i've not had much luck tracking down memory (and I gather the stuff
that is out there usually is a bit expensive). On the other hand, I'm
looking into getting a VAXstation 4000/VLC with 24 meg, which should
be a little bit more useful for general VMS exploration.. then I
could set aside the 3100 more for preservation and "waiting for parts".

You can copy or give them away under the hobby license program. So if
you have a working system and TK50 you could copy them onto someone elses
media. they would have to get a DECUS license for their system.
Basically DEC copyrighted the programs on the media and still claims
ownership but allows use for noncommercial use, under that case Copying
it for the same use is resonable. I'm sure there are some fine points on
this I'm missing.

Speak to the guys down at MONTAGAR.COM, they cut and distribute the VMS7.2

$30.

I got some RC25 carts (now gone with the departed 11/725) from a local company
that used their 11/725 as a boot manager for the office VS2000s. It was
running VMS 5.0. It *barely* fit and was probably not supported.

I think the official max for the 11/725 might have been 3 or 4Mb, possibly
due to cooling restrictions - it was the same power supply as the 11/730-Z,
so it wasn't power, per se. I had 5Mb in my 11/725 and never had a problem,
supported configuration or no.

I never saw a third-party board over 1Mb for the 11/730, not that there weren't
such beasts. My employer would have bought one if it were under $500/Mb. We
did have some EMC 1Mb boards that used 256x1 DRAMs - same board size as a DEC
1Mb board, of course, but 90% empty. I threw them into the 11/730 as we found
them because they obviously used less power and generated less heat. Good,
solid boards. Never had one fail (can't say the same for the DEC boards, but
we did have every machine maxxed out providing more statistical chances for
failures).

Works fine either way. Mine is in the side slot and the top slot is for the
RX33's.
Do you just need the foot or the complete shell for the BA23? I have a
bunch but the shell is a real PITA to ship. I have a H*** of a time finding
boxes for them. I even checked on having some made. About $4.50 ea. with a
100 minimum quantity.

My first exposure to VMS was around September, 1984. ISTR that it was 3.4.
It was on an 11/750 w/8Mb+RA81. My employer paid $26,000 for that drive, too.

Hmm... I never had a lick of problem with mine. Maybe I was just lucky. I

the RZ23 is a tad small but the 3100/m76 16mb is otherwise fine for 7.2.
Try and find a RZ24 or better yet a RZ25(1GB) scsi. The install really
wants (full boat) a RZ56 (667mb) for comfort but there is easily 250mb free
after your done so you can see it works.
If you want to live only with a RZ23 then early V5 such as 5.4 or 5.5 is a
good choice if you don't install DECwindows or the optional libraries.
I've jammed 5.4 into a RD53(71mb) with 11,000 free blocks when done!

The only reason I know is that it's hard to remove the silicon oils
and you cant solder through it.
The contacts should be cleaned first, a little bit of silicon based grease
or oil is ok to protect the surface but globs of it is not desireable.
If you have solder problems keep the silicon grease away until fixed!

You can bet the system is slow though. It takes a lot of swapping to run
at all in that little. get another 4mb and you'll be plesently surprized.
<I don't know if I should be scared or impressed :^) I'm surprised the V7.
<even let you do the install! What can I say, I'm impressed!
VMS does have a minimum and it's somewhere between 2.5 and 3.2mb for V7
as that much ram must be present for the "core" system for the resident
portion to run. The rest is swappable.
Allison
Yeah, probably for the long term, but if you want something to play around
with _right now_ its not bad in terms of responsiveness and very basic
usability.... I pretty much crammed the whole base OpenVMS 7.2 VAX
system on there (sans DECnet) and still have about 8 megs to spare :)
Personally, I was rather surprised that OpenVMS would fit (usably, albeit
not much) on such a small drive in the first place :)

I don't know if he is under assured destruct. The boards I purchased from
him today were from a University Research Center (a supercomputer in their
lab) so that would not fall under it (I imagine). I do know he is willing to
sell me some super computers and some must have serial numbers removed... I

super computers???

Wow, _very cool_ in my opinion :) Those are old HP/Apollo workstations. They
run either HP-UX or Domain/OS UNIX. The Series 400 was the last 680x0 based
series of workstations that were produced by Apollo shortly after they were
purchased by Hewlett Packard.
Definently interesting systems; especially if you got one running Domain...
I believe you can run NetBSD on _some_ 400 series systems (perhaps just
the 425t; I have not checked in a while) if you're looking for something
a bit more current.
They do need fixed frequency monitors to run; and I think the keyboard/mouse
on them are HP-HIL (although there may be a second alternative interface
also; i've never actually seen one; just read about them :)
In any case, if you don't want one of them, and are willing to ship it, i'd
pay a few bucks for one :)

Definitely not for the boot disk. The most basic VMS kit (that is,
without help pages, without libraries, certainly no DECWindows!) for VMS
6.1 won't fit in the 25 Mbytes available in a RC25.
6.2 "officially" requires more than 120 Mbytes for a basic installation,
but if you fool its installation procedure you can shoehorn it onto a
RZ23 (100 Mbytes)

Officially the 730 only holds 5 Mbytes. I don't know if there's any
way of extending this.
Remember also that the RC25, if the "fixed" platter is used as a system
disk, can be spun down to change the removable data platter. The host
OS needs to be aware that its system disk might be spun down, and it has
to be patient enough to wait for it to come back up. The PDP-11 OS's know
how to do this, and the last version of VMS to officially support the
725 with RC25 knows how to do this, but I don't know if they included
support for this in the more modern versions of VMS.
My 11/730, when I had it, ran VMS 4.6.

I know of a 11/725 still running a monitoring/logging application at a
nuclear power plant, booting from a RC25 under VMS 4.2. And yes, they
could upgrade to a SCSI drive and Unibus SCSI host adapter.

I'll be *really* impressed if you also tell us that you're running

Keep in mind that "unsupported" doesn't mean "won't work". It just

Today I found several HP Apollo Series 400 Computers headed for the
dumpster.
These were used as I think some sort of Servers for a medical facility.
There were 20 or 30 of them I only took 5..
Opened them up and they each have a SCSI hard drive and I think 32MB RAM,
However they have no Floppy drive, ISA or PCI slots in them..
They support 3 serial ports, Parallel Port, SCSI Port, Kybd, Standard
Network Interfaces, and Audio In and Audio Out.. They have a place for a
second SCSI drive also in them.
The Processor looks to be a Motorola 68040 I think..
I hooked up my VGA monitor and powered up , but it appears to be out of
sync, or a non-standard VGA out put. I could see part of a color screen, but
the screen seemed out of sync and not really readable.
Does anyone know what these are ?,
And other than parts are they worth anything.?
Can I do anything usefull with them.. ?
Thanks,
Phil
I picked up a core memory board today that was made by Ampex's Memory
Products Division. The date code is 8010 and the ICs are dated 1979 so it
was probably made in early 1980. The sticker on the board sasy that it's a
32K x 18 memory. The board is BIG, 11 x 14 inches and has assemble number
3293212-01. Does anyone have an idea of what it's for?
Joe
I was given the name of a company a couple of days ago through the company I
am getting my Super Computers from. They told me to give this guy a call and
see if he had anything I was looking for. I called the number and asked to
speak with an officer of the company.. the answering service took my name
and number. About an hour later the owner of *this* company called me back
and asked me how he could help me. I told him I was looking for old
minicomputers, not some flake.. paid for shipping and paid more than scrap
prices... I asked him if he ever got minicomputers/mainframes in.
(getting interested)
He laughed at me and said his crew of *20* goes through and cuts up for
gold more than 15 MILLION pounds of mainframes per year. (I thought he was
full of shit). I told him my scrapping company name and he invited me out. I
flew to his place and this is what I saw:
When I got there I saw a huge building with an office. In the back of the
building there were 4+ forklifts driving around like mad with skid fulls of
IBM mainframes and dropping then op top of each other. When I pulled around
and parked my rental car I saw a guy with a pair of shears inside an IBM
1130 :-( chopping it to pieces. I went inside this *factory* and 40 feet
high in places were stacked super computers, minis, micros (apples, PS/2,
micro vaxes, etc), and an unbelievable number of boards. After touring
through the work area I found the office and talked with the owner (was
rather busy).. He gave me a quick tour showing me some super computers they
were hacking up, HDS (Hitachi data Systems), IBM 3840?, and some other water
cooled high speed CPUs. It blew me away.. I never thought there was such a
large gold processing site for this.. that's all this company does. They
also melt down CPUs direct from IBM , Hitachi, etc... I missed a bunch of
old DEC stuff by one day.. They guys were just finishing killing a bunch of
PDP-8s and 11s.
(here is the positive spin):
Of course being in total shock (I never saw so many apple computers piled to
the ceiling waiting to be stripped)... we talked price on some of the
systems. I can't buy them from him at scrap prices *nor* will he put systems
aside... I asked him if I could go through the warehouse and check for some
parts (promised not to be a nuisance).. I found a heap of super computer
boards and brought one to him [the other stuff I wanted had been
butchered.].. he did not want to sell them at first as he was *required* to
destroy them.
We came up with a deal:
Any mini/mainframe computer with front panel switches and light will be put
aside for one week. I have to fly down every week to see what he has there
(quickly) and purchase immediately what I want. As my references panned out
he will allow me to purchase boards and equipment from him under three
conditions:
All serial numbers removed.
I don't publicize what he is doing to historical computers. [don't know why
he cared]
I *agree* to destroy anything I buy from him ;-)
**** His company generally pays $8-10K for a super computer as the raw
materials when extracted are generally worth 4X that! [I did *not* know
that.].. I spent more time with him and he showed me the insides of some of
the huge IBM mainframes...[water cooled].. can't say I ever saw one
before... He *only* new the metal content in every piece and $$$ .... HAHAHA
(rather funny... no idea of the technology)
We also cut a *really* sweet deal. He owns a transport truck line and his
trucks pass through Toronto *empty* every couple of weeks.. he agreed to
pick up any systems I wanted around the country, drop off the ones I wanted
and he would pay me for the systems I would not want [every load must of
course have a mainframe or mini for him).
I bought some super computer boards at slightly above gold prices... [you
will see them on EBay].. They are *amazing*. Processors beyond belief...
I will update everyone with a list of the minis I get and will keep my eyes
out for the systems in the wish lists I have received so far.
Never in the world did I ever expect to see a few thousand minis, mainframes
and micros being scrapped by so many people.... BTW: That stuff in his
warehouse came in over the past two weeks *and* while I was there, there
were 3 transport trucks waiting in line to dump off loads of water cooled
IBM/Hitachi mainframes.
On a sad note, on the way out I saw a front panel with all kind of lights
and switches.. It was 8 bit and was made of plastic... It was called "data

Some time ago i found one of these systems. It also included the original datasheets from National. It says that the voltage on pin 40 must be -7Volt.
When you need more info i can send you a scan of the datasheets.
Unfortunately my system doesn't function. So i'm looking for the scematics. Maybe you can help me out?

Thanks for replies regarding the cable. It turns out that our
cable wiring is ok and the AXP firmware expects 9600,8,1,n although
it will display at 9600,7,1,e. Attempts to run 'cu' on the unix
host (which provides the terminal session) at 8bit no parity creates
a session at 8bit odd parity (a longer total frame) which confounds
the AXP. Using 'kermit' instead is the solution for now.

I still wonder why. The only thing I can think of is that either the driver
for the RC25 was removed or that VMS would no longer fit on an RC25 cartridge
as a boot volume. The drives used two platters, one fixed, one removable, 26Mb
each. You spun them up as a pair. When I got my 11/725 in 1988 ($4K), the
guys who shipped it didn't ship it with a removable cart (they also shipped
it sans grant cards and the terminator shoved all the way up the UNIBUS which
fried the PSU on power-on).

It's a little larger than a BA123 and about the same proportions. I wanted one
because it was the most affordable VAX at the time. I wish I still had it.
:-(
Fortunately for me, my boss paid the $4K, I only paid $1.5K for it.

An off-topic thread that has already gone on too long - but I've only had time
to reply to the "swords" subthread so far, so here goes anyway...
Of the things I collect, mostly in small quantities, I think coins and cars are
the only ones _not_ screwy. So:
Classic computers (of course)
Hymn books (full music editions if I can get them)
Musical instruments.
Ah yes. Musical instruments. Definitely the screwiest thing I collect. Why?
I have only one piano, and a bassoon and a banjo and a guitar and ...
Well, I collect electronic keyboards, the older the better, like classic
computers. Heck, some of them practically _are_ classic computers.
And I collect ethnic instruments from the strange parts of the world I visit.
(I wish I'd bought that dulcimer in the traditional instrument shop in
Bangkok...) Like, in Jakarta, I bought a gong. 28 inches in diameter, and
weighing, um, I was going to say nearly 100lb but I think it's a bit less. I'll
have to weigh it. I wish I'd known how expensive excess baggage charges are ---
it cost me $700 US just to ship the damned thing home...
When not in use at concerts and things, the gong does duty as my doorbell. I
wondered about a mechanical system, but settled in the end for an electrical
one: solenoid is driven by a monostable made from two relays.
Screwy enough for you?
Philip.

http://cpm.interfun.net/ is now the main site for the unofficial CP/M
web page. Indeed there is a PL/M compiler at
http://cpm.interfun.net/binary.html it's the 8080 ISIS version packaged
with an ISIS emulator for MS-DOS that provides just enough functionality
to run the PL/M compiler. Intel had this available for download from
their web site (as well as a PL/M-51 compiler) for some time, but I
haven't looked recently to see if it's still there.

I have a MicroVAX 2000 that was used to test the hybrid data separator
in the 3100 as they came off the assembly line. It has a plastic box
attached to the top with a ZIF connector, which is wired to the guts
of the 2000 such that the 2000 can reroute the data from the disk drives
through the ZIF connector. The test app runs under VMS; it locks itself
into memory, switches to the hybrid data separator, then runs tests on
the data separator using the disk (RD32) from which it booted.
I'll have to take a picture of it someday and put it on a web site
somewhere.
I wound up with it because the company that made the data separators
couldn't figure out how to break into the system. I had the console
auto-log into an account that just ran the test app. All they had to
do to break in was hook a terminal up to the 25-pin port and punch
ENTER...

There's a PL/M80 compiler written in FORTRAN IV on the Walnut
Creek CP/M CDROM. I've used it under VMS and spit the source
through Microsoft's F80 (it took a little tweaking and the
resulting object files were so large there was no point in
attempting to link them). Gene Buckle has a copy of the CDROM
hanging off his CP/M page at http://deltasoft.fife.wa.us./cpm/.
Take a look at http://deltasoft.fife.wa.us./cpm/cdrom/CPM/MISC/PLM80.ARK
in particular.

Yes. A daughter card for the CPU and a card under the skirt with a 36-pin

of a cable. The distribution card goes next to the SCSI-1 connector and
the DB50P connector for the external RD53/RD54 drive.

Well... to inventory...
2 MV2000 w/6Mb, 2xRD54 (one TK50Z-FA to share, one with DHT32 serial add-on)
2 VS2000 w/unknown (recently aquired from a friend's estate, untested)
1 uVAX-I w/4Mb, RQDX2+RD32+RX50
1 uVAX-II in BA123 w/9Mb, RQDX3+RD54+RX50, KDA50+shared RA81, DEQNA, TQK50
1 uVAX-II in BA23 w/17Mb, RQDX3+RD53+RX50, KDA50+shared RA81
2 11/750 w/8Mb and 14Mb, SI9900 each, Fuji Eagle, UDA50, Emulex serial, etc.
1 11/730 w/5Mb, RB80+RL02, DMF-32.
1 8300 w/16Mb, KDB50+shared RA81, DEBNT
The uVAX-I, one uVAX-II, one 11/750 and the 11/730 were purchased by my former
employer new from DEC. The 8300 was purchased used (at $12K), and I picked up
the rest of the stuff in more recent years when stuff was essentially at
"haul it out of here" prices when it could be found at all.
Only the MV2000s are networked to anything. The 11/7xx machines are in
storage for a while longer; the 8300 is set up in the basement, but I've
never gotten the DEBNT working (cable issues, I expect; I only added it
last year, played with it for a couple of evenings and moved on to other
tasks). I've got a lot more VAX equipment than time to play with it, but
once upon a time, I _did_ run a support organization from my basement (1992-
1995). Everyone has a 30A Hubble Twist-n-lok receptical attached to
their breaker panel, don't they? I'm looking forward to a powerful VAX with
modern low-power disks and minimal electricity consumption. I only wish it
came with a TZ07(?) SCSI 9-track drive. Then I could easily archive my magtape
library.
> My fix, skip the connectors, soldered connection.
Well... that's certainly one solution I hadn't considered. It *would*
be more reliable, and really, how often do you need to change out a TK50
motor anyway?

Ah... you needed the scripts I wrote eleven years ago... they would
build a console TU58 with EXCHANGE and sling the files out to the tape
in the right order. The benefit was that apparently the microprocessor
in the TU58 (at least on the 11/730, don't know about the 11/750) would
buffer the directory so that the only seeks were to *read* files, not to
*locate* the files.
Our 11/730 reboot time went from 18 minutes to under six with properly
constructed tapes. It became a function of the serial line speed and
tape velocity, not of random seek times on a 250-foot tape. You heard the
drive go and go and go with occasional pauses at each new file. Every
time I rebooted I was glad I'd taken an afternoon to automate the building
process (which I had to re-do with every VMS major update).
Boy... lots of VAX stuff flying the past few days. I'm going to have to
fire something up and remind myself why I don't use 1980-vintage hardware
on a daily basis. It was fun, but *damn* it was slow. I got a lot of reading
done back in those days... seven hour offline backups, five hour upgrades...
oh, yeah... the "good" old days. ;-) At least the stuff stayed up for more
than ten minutes. Our record was 45 days between VAX reboots, but only because
we were developing software and would have periods of several reboots per day
to clear device drivers. Since then, I've seen uptimes on the cluster at
Lucent
measured in months.

If at first you don't succeed, nuclear warhead

I have found that the Canadians call all thier electric power "hydro". The
term is probably rooted in the early use of the Niagara escarpment for
actual hydo-electric power. But, IMHO it definately puts "Clean Spin" on
thier NOW heavy use of Nuclear power.
To Americans, It seems inherent that Canadian water is pure. Hydro says
"water" = pure.
When in reality Canada runs a goodly risk of contaminating the Great Lakes.
Fact: Canada has a huge nuke plant north of Kincardine Ont. on the Bruce
Penninsula.
Fact: Canada's largest Oil terminal and Refinery is on the St Mary's River
in Sarnia Ont.
Fact: The Canadians have a network of gas wells "under" their side of Lake
Erie - east of Long Point. The wells actually break the surface of Lake
Erie with White and Orange pipes about the size of Canadian Spar Bouys.
Occasionally these gas wells are struck by ships & boats (coming in or out
of the Welland Canal)during storms - and they do leak (I Monitored such a
leak being checked out by the Canadian Coast Guard on Marine VHF July
1-3,1998, while at Sugarloaf Harbor in Port Colbourne.)
To me, all of these are higher risks for water pollution throughout the
Great Lakes Area.
Yet, Canadians keep blasting the USA for Coal use causing acid rain.
I guess its all in the way the wind blows, and who is monitoring the leaks,
spills and resource quality.
OTOH, I wonder how many computerised process controllers were/are used in
Power generation. I had seen an internet report on the Perry Nuclear
Plant(Port Clinton, Ohio,USA) recommending taking a microVAX offline for Y2K
compliance sake. Ironic, I found this list while searching on MicroVAX as
well.

Hey! What's wrong with the 11/725? I used to have one until the company
that was borrowing it folded. I didn't find out until my VAX was gone. :-(
Essentially, it was an 11/730 w/RC25 as the primary disk device, but you
*could* stick other stuff in there. I even knew a company that ran a BA-11
box off of theirs, but DEC *did not* support that configuration.
It was a packaging issue. There should be no way to tell an 11/725 from
an 11/730 in software.

There is no low-level format commands (like a BIOS format) from within VMS.
That stuff is all done from rare Field Service diagnostics. I don't know
how to do it from a MicroVAX-I. With the right tape, it's just a bunch of
menu questions for a MicroVAX-II w/RQDX3.

Cool. It might be an Emulex SMD drive interface (they were common third-
party devices at one point). If the cables to the drive itself are a 60-pin
and a 26-pin, it's SMD. If the cables are 34-pin and 20-pin, it's most
likely ESDI.

AFAIK, yes. The issue becomes distribution. The hobby OpenVMS distro is on

future.

I don't know the minimum system requirements, but I would expect that you
need 200Mb to load OpenVMS. VMS 6.1 barely fits on an RD54 - 154Mb, the
largest you can use on your MicroVAX-I if you happen to have an RQDX3 (you
probably have an RQDX1 or RQDX2 - quad-width cards). One of the reasons I'm
looking forward to getting that MicroVAX 3100 is it will free me from the
tyranny of small, slow, fragile and increasingly rare MFM disks. One downside
I caught from a FAQ is that SCSI MicroVAXen don't like disks over 1.07Gb -
too many blocks to keep track of with a 21-bit pointer. Fortunately, I have
a couple of old DEC 3105's I can pull off of an Amiga. Quite the disks in
their day, but discards now.

I don't have a copy in the original dialect, but I do have a machine-readable
copy for the PET. I typed it in and modified it about twenty years ago.

The ongoing PDP-8/L restoration saga adds a new chapter. I was working on
a pair of them the other night and ran into an aggravating problem. The
area of the backplane around D-02 through D-15 that holds the M310 delay
line modules is giving me fits.
I have the power-restart option in and on. I turn a machine on and it runs
the lights in a random and pleasing fashion - the MA register shows some lights
brighter than others and the AC occasionally shows changes. After a few
seconds, the display gets more static - some of the lights in the MA get
brighter than they were; some get dimmer. This indicates to me that the
same region of memory is getting hit with a higher frequency. Now, here's
the annoying part: if I stroke the M310 cards, the display usually goes back
to a more random distribution of bits in the MA.
The M310 cards are instrumental in the timing flow of TTL -8s. I appear to
have a dirty backplane or loose backplane connector fingers. Without replacing
sections of the backplane (don't laugh - I have at least one new-in-the-box
p/N CAC-1 backplane section), how can I increase my connection reliability?
The card fingers don't show any visible corrosion; the gold looks intact. I
suspect the quality of the tin-plated steel in the backplane. Can say that
these are especially tight, either.
I'm not even as far as being able to reliably change and examine memory with
the frontpanel. Diagnostics are somewhat distant aids at this point. I'm
relegated to an oscilloscope and hand tools.
Any tips?
Thanks,

Well, you can still buy brand-new ZX81 kits for $49.95 . . . and the 16 KB
RAM expansions are readily available for about US$5-10 ;>)
Essentially, I use the PC as a device to transfer programs from FTP or Web
sites to my small computers: download the program, send it out the sound card
to a tape, then load that tape into the smaller computer.
There are presently over 10,000 programs available -- all free -- on FTP/Web
sites for the small computers I collect. Unfortunately there are groups in
the US which oppose this activity -- not because any of the program authors
are objecting at this late date -- but because these groups propose that
*any* form of emulation, or use of *alien* hardware, to run, store, or
transfer these programs is illegal and should be stopped.
Their reasoning is: if I never bought a ZX81, but I use a ZX81 emulator on my
PC to run ZX81 programs, then what is to stop me from using a Sony
Playstation emulator on my PC to avoid buying a Playstation?
My opinion is: the major game producers are afraid that if the public finds
out that for well under US$100 anyone with a PC and a modem can pick up an
"obsolete" computer and get 10,000 games, free, the new hot-rod game machines
might lose a few sales.

I wasn't clear. Sorry. Yes, the *boot* device can't be over $1FFFFF blocks
long because of the limitation in the SCSI commands used by older firmware.
One reason pointed out in the FAQ is that the system dump *could* overwrite
the first couple of tracks if the disk is over 1.07Gb and conditions are
right.
As has been pointed out, VAXstation 3100s are not upgradable; later MicroVAXen
are either upgradable or no upgrade is necessary.

Hi all
Just thought i might try my luck here. I'm looking for *ANY* PL/M
compiler ( PLM80 PLM51 PLM96 PM960 PLM86 )

anyone got any clue where to get these ?

I found an Emulex CU04...... Qbus card today. Being the curious type, I
picked it up.
It's got a 34 pin header on the handle edge, and about 15 feet of

Now for the question of the day: What is it?
Any thoughts?

Would you happen to still have that keyboard? I know I'm sending this almost
a year after you posted your original message but I just figured I would ask.
I happen to have one of those keyboards and it grew on me. I didn't care for
it when I first bought it but I love it now. Unfortunately, its getting old
now and many of the buttons are starting to not work anymore or double type.
I have been trying to find a replacement for it but they are rather tough to
find. I really dont care for the current straight keyboards now that I am
used to the adjustable one its hard to go back. Not to mention that I tend to
make many more typos with a straight keyboard since Im used to having it
split all the time. Let me know, I would appriciate it. Thanks!

Greetings.
Life's tough without manuals. We'd appreciate some help with configuring
an async terminal as console on a DEC 3000-M400 (and to remain on topic
advice for the same on VAXStation 3100). After an exhaustive 'net search
with little success researching cable data we empirically wired the
following cable:
MMJ-F,front view DB-25F Unix host
DCE? DCE (multiport ctrlr)DTE
-----
| 1 |----------dtr------------------ 20 dtr---------cd
- 2 |----------td------------------- 2 td----------rd
| 3 |----------td gnd---|----------- 7 sgnd--------gnd
| 4 |----------rd gnd---|
- 5 |----------rd ------------------ 3 rd----------td
| 6 |----------dsr------------------ 6 cd----------dtr
----- |- 5 cts---------rts
(pin nos are conjecture) |- 4 rts---------cts
Setting the terminal for 9600,7,1,e produces a readable display during
boot but commands entered to the firmware monitor and/or to SYSBOOT
are invalid even though they echo properly. Only the single '?'
or the letter 'c' function as intended. The system works properly
when used with the attached keyboard/display (with the 'alternate console'
switch in the other position). The terminal works properly as a
login terminal under VMS (6.1 AXP) using this cable. Using other
parity, framing, baud, etc. doesn't help.
Also, the machine came without UCX (TCP/IP) and has no
floppy or tape at the moment. We'd like to transfer some files over
the serial cable (uuencoded or otherwise) and have tried 'COPY OPA1:
FOO' which works except that an interrupt (^C) doesn't close the file.
The proper procedure would be appreciated. Is there a terminal program
bundled with VMS 6.1 (we couldn't find one)?
We'd also appreciate advice regarding obtaining VMS documentation beyond
the online help system and 'net faqs (I can't imagine becoming fluent
in DCL or VMS otherwise) and hardware documentation for 3100 and AXP
series machines (one would hope that microfiche or cd-rom versions
exist by now).

On the subject of the nonbooting HDOS disks, I don't think there's
anything wrong with the machine (I have two separate machines
exhibiting the same behavior, after all) -- I think the disks are just very
borderline. I adjusted the rotational speed on one of the H89's
(it should be 200 according to my Heath manual) and then was able
to get one of the HDOS disks to almost boot. But part way through the
boot sequence it gets some unpleasant error and complains. So I
suspect that if I had a fresh copy of an HDOS disk it would boot.
Still don't know why the CP/M disks fared better, but perhaps they're
a bit younger...

Well yesterday was a great day as I added 17 more manuals to my collection and some items that are not yet ten years old. I also picked up Toshiba T1200 not working right now, no charger for battery. I got a HP 35660A Dynamic Signal Analyzer. The other 15 items range from Apple to IBM to Maxtor and where 4 to 8 years old and will go into storage for display later. I started working on my web site and hope it have it up soon with pictures. Keep Computing John
A quick pair of questions to the list out of curiosity:
Do you think there is much data out there on older storage
media (paper tape, punch cards, 7-track tape, 9-track tape)
that is waiting to be converted to newer (cd-rom, 8mm) media?
Are there commercial firms that specialize in such transfers/
conversions of data from older media to newer media?

It's been my (unofficial) experience that a VAX usually seems about as
fast as an Alpha running at twice the clock rate; so my 4000/96 at 83Mhz
or thereabouts is roughly equal to my 3000/600 at 150MHz or thereabouts.
Of course, every now and then the Alpha slaps you over the head to let
you know that it's really fast.

There's no reason why not. When you say disk driver, I assume you mean disk
drive (the DRIVE is the piece of hardware into which you put the diskette,
the DRIVER is the software with which you operate it).
How you go about it will depend on a number of factors, however. Mostly
it's how much work you want to do. The AIM65 ( I have a couple of them) did
not come with a disk drive or an interface to one. You must have some
information about your particular interface. If you do, that will shed
light on the details.

For cheap? Either a stepping relay or some kind of PIC might do it. I
don't know how you'll do it for under $25, though. I have this one relay
that would do it - it looks like a clock face on the back with thirty or
so solder points. There are two relay inputs (110VAC) - step and reset.
With something like this, it would be possible to assign a number, 28, say,
and require that all the digits add up to that number. It would be, in effect,
like a 1920's central office, but with a one-dimensional stepper instead of
a three-dimensional stepper. Those things are fun to watch if you ever get
to see one in a science museum.
Perhaps you could simlate that relay in solid state? If you have a circuit
that will detect tones, perhaps you could run another connection from the
same line conditioners to a series of decade counters. The phone number
wouldn't be software settable, but it might accomplish the task. The trick
is that the phone company designates a minimum time between pulses on the
same number and a minimum interval between numbers. Old dial phones had a
mechanical governor to space the pulses jost so and to prevent the next number
>from starting too soon. I'd tell you the timing, but I just don't know. If
I had to, I could hook up a scope/timer to this old dial phone I have.
> As for ring... I am thinking using two charged capacitors and switching

The cheap-o boxes I've seen worked by running 110VAC through a half-wave
rectifier and current-limiting resistors. It's not perfect, but there's
lots of tolerance on the part of phone equipment.
My dad used to work for the phone company when he was right out of high
school. Much later, when we were growing up in the 1970's, he had a
box of old phones. We ran wires from my room to my next younger brother's
room and just hooked a couple of batteries in the circuit and had a non-
ringing intercom. I don't recall the voltage, but I think it was only 6v
or 12v. True telco voltage is, IIRC, -48VDC.
> Any suggestions? I'd like to do this for less that $25.00.
I've seen telco simulators made in electrical junctions boxes sell at
hamfests for about that. They didn't do any sort of dialling detection,
though. I used to make a Cadillac telco simulator... I still have a box
of parts and boards. We charged $800 for them. They would do half-
connections, failed connections, fake busy, etc. The only think I ever
used them for was to program an V.24 autodialer driver for our sync
datacomm products. The rig was two of our own MC68K serial boards in the
same BA-11, two Motorola 2400 baud sync modems and this box. Ny changing
the dialed phone number, I could change the behavior in the telco simulator
to force the modems to generate BUSY messages and NO CONNECT messages to
run the dialer software through its paces. It was a hoot.
The cheapest ones I've seen that did anything more than provide voltage and
fake dialtone were around $200.
Good Luck,

Decoding the pulse dialing should be easy enough. If you consider what the
mechanism was 40 years ago, i.e. the mechanical central office, with
stepping relays which responded to the pulses created by your telephone, it
will become obvious that what each number did was drive a stepping relay
which selected which bank of relays would be the destination of the next
stream of pulses. If you count the pulses, which wil be at either 10 or 20
Hz, depending on the age of the telephone generating them, you'll get the
number dialed. count/time the pulses. When one pulse is missing or 10 have
been accumulated, go to the next digit ...
Certain digits have special meanings, i.e. starting with a '1' meant it
should expect a 10-digit number instead of a 7-digit one. A '0' also had
special meaning, didn't it?
If you poke around in some of the older National Semiconductor data books,
there are plenty of circuits which they no longer sell which show details of
how many of these functions are created, including the DTMF decoding, etc.
EXAR and Signetics published lots of examples also. It's no coincidence
that they all sold PLL components.

Probably quite a bit, yes.

Yes indeed. In fact, I run one. ;-)
(SHAMELESS PLUG ALERT) www.bluefeathertech.com/media.html for details.
HOWEVER -- if it's just a minor job for a fellow listmember/classic
computer user, like copying a distro tape or writing a NetBSD load onto
some oddball media, I typically don't charge anything other than shipping,
or I give a big fat discount on my published rates. Others have done the
same for me, and I certainly don't see any reason not to do it for others.
