It might be the drive itself, I'd try a 1X drive if you have one.

Subject: Booting a VAXstation 4000 VLC off the hobbyist boot CD-ROM
I have my VAXstation 4000 VLC running to the ">>>" prompt and would
like to boot the hobbyist CD-ROM to install VMS on the hard drive but
I'm having trouble getting the CD-ROM to boot. If I type 'boot dka400'
at the prompt, the CD-ROM spins up and I get the text "-DKA400"
displayed on the console but then I get the ">>>" prompt again. Can
anyone tell me why that would happen? I'm using a NEC CDR-1910A SCSI
CD-ROM drive set to SCSI ID 4.

Hmm. So in your mind experiment you keep the 12 sector pulses and
the track pulse, and deliver the track pulse with 16 sector pulses
to the hardware of the drive logic.
Using the 12 sector pulses will probably produce a more stable 16
sector pulse signal as the PLL is kept in lock in shorter intervals.
But what would the PLL circuit do when it gets 12 sector pulses
(that is fine) *_and_* at some odd moment the extra track pulse ...?
I was thinking of *only* the track pulse and get the PLL locked on
that pulse only, assuming that the stability of the PLL is sufficient
for one revolution. From the N divider is would be easy to get the
sector pulses. So, I cover all the sector slits on the hub of the disk.
But as you said (I did not know that part and did not check on an RK05
pack I have at home), the track pulse is not halfway two sectors.
Some separate binary comparator could check the N divider outputs and
then you simply set a binary number to the comparator when it should
give the track pulse.

I need some Persci 8" drives (model 270 or 277) and/or parts to repair them

atleast 15-20yrs old. i fig that it has a NECV30
(similar to 8088) i guess.
no idea if its still in workin cond. i tried checkin,
the powersupply's alright, and the power reaches the
processor and the other chips. the bios chip is on
board (andi doubt that's the trouble maker)
can somebody tellme where ican find some info on

I have a VAXstation 4000 vlc without an internal hard disk and a spare
RZ25-E drive. I had thought I could install the drive in the vlc but it
seems from inspection that the vlc needs a lower profile drive. What
drives are compatible with the vlc? If it won't work as an internal
drive, I guess I can install the RZ25-E in an external SCSI enclosure.
Should that work with the vlc?

Sorry, me again.
Mentioned TMS2532 Eproms are one of these Unobtainiums here.
Looking at the Pinouts I have in my databooks there are
little (minor?) Differences to the standard 2732's (besides
the different Program Supply Voltage). I couldn't find much
ressources online, but would it work if I made a small
adapter like "illustrated" below...
2732 2532
EPROM -> SOCKET
Pin(s) Pin(s)
1-17 -> 1-17
18 (E) -> 20 (PD/PGM)
19(A10)-> 19 (A10)
20(GVpp)> 21 (Vpp)
21(A11)-> 18 (A11)
22-24 -> 22-24
Please correct me, if I'm completely wrong and trying to do
something impossible.
2732's would be easy to obtain, and I have some
prommer-schematics and software handy. So it would be cool
if I could use them.

I've yet to find anyone who has a running one :-) The ones I've seen
typically had BASF hard drives, which don't seem to have stood the test
of time like other ST506 units. Yours is a little unusual in having the
68k board rather than the Z80 though. (I've got schematics for the 68k
boards by the way, as well as the SASI controller fitted in these

I'm very interested in a copy of the 68000 and SASI boards. Any chance

The differences/peculiarities/innovations exhibited by many of the old
machines make them so fascinating. If you give me a 20 year old PC,
it will take me no time to setup it up with DOS and even networking.
But what would be the point, I can do the same thing in a VMware
window on my Linux workstation.
The neat thing about the old machines is that it takes for ever to set
them up and this is what's so intriguing about them. I remember a
posting (not in this forum), about a guy who got an old IBM 360
mainframe working. He said that once it was working there wasn't much
to do with it.

I am afraid that computing standardised too early causing everybody to
get locked into a technology that is too clunky. Microsoft's "innovation"
essentially boils down to two things:
a) adding useless junk to their already bloated platforms, and
b) adding "essential" applications (e.g. Web, or audio) to their
base platform so as to dictate the standards and eliminate
competition.
This strategy, although excellent for Microsoft, is to the detriment of
everybody else.
I have PCs running windows because I must, but I don't need the latest
and greatest Microsoft offering, I am running Windows NT4.0 with Office
95 (which btw will soon be covered by the 10 year boundary :-). I will
soon have to move to something more recent mainly because vendors do
not support Windows NT, so I will not have the drivers to run Windows
NT on my new hardware. PC hardware *is* a commodity, but never be fooled
into thinking that Windows software is also a commodity.

I've got a pair of non-working Commodore SX64's here.
One machine powers up, but the floppy drive light remains lit and I can
hear the drive spinning continuously, and there's a 50% grey pattern
filling the screen (i.e. pixels look to be alternating white/black).
Actually, there's also short run of pixels middle-bottom of the screen
which aren't illuminated at all. Pressing reset has no effect. Pressing
caps-lock does result in the caps-lock light illuminating, but I don't
know if that's a simple circuit hardwired to the key and doesn't go via
the CPU...
The second machine is totally dead - no activity whatsoever. There's a
*very faint* humming noise from the monitor area, typical of a display
that's at least getting power though - but on the CPU side of things no
chips seem to be getting remotely warm, suggesting that there's no +5V.
Before I start digging deeper, does the fault with the first machine
sound familiar, and are there any common PSU faults which affect these
systems? Plus, anyone have schematics they could scan?
Be nice to get one of them going. One keyboard is damaged (plus I only
have the one original keyboard cable), so it's only really viable to
have one running, but I'd like to get to the bottom of what's up with
both of them...

Crisis Computer in San Jose has the equipment to write CE packs.
They aren't going to be cheap. I'm guessing $300 to $500.
They are probably the only place in the world left that has the
gear to do this.
Realigning 2315 heads isn't something you want to do if you don't
absolutlely HAVE to, since you run the risk of making the packs
that you have unreadable, if they were written on drives that are
off spec.
-------------------
I believe I have to consider this. I have no packs with any data on
them that I need. They were all just data packs with automotive
parts in inventory and such. I cleaned a pack and loaded it into
my RK05 drive zero and it would not pass the read/write test. I don't
remember what happened when I tried to use drive 1. I believe it failed but in a different manner. I thought if at least one drive
was working I'd be Ok for awhile. I am not sure if I want to spend
$300-$500 on trying to get a CE pack that may not help me if my drive
is failing for some other reason than alignment.

Thanks Pete for your fast answer.
Yes it is a BASIC 4 Machine with these 4116-4 RAMs.
You wrote the correct substitute for the ROM chips are
Texas Instruments TMS2532 or equivalent. Is this right for
all the chips I will list below? I hope the TMS2532 are
easy to purchase here in Austria. Looking through my
little library I found the datasheet (at least a good
start) but I couldn't find a refence for substitutes - do
there exist any? Are the TMS2532 fully Pin-compatible with
the MOS ones? And my last question: Do I need anything
special to write these chips? I'd put together a little
circuit to hook on my Pc's Parallel-Port (this would be
the easiest way for me). I'm already googling for
information, but would be very glad of some links to
schematics and software.

If it's BASIC 4 and dynamic RAM chips, it should be 4K ROM chips, and
the EPROM equivalent is Texas Instruments TMS2532 or equivalent. Note
that this is not the same as the more common Intel type 2732.

It depends on exactly what type of PET you have. But I'm not sure
there's a whole set there, for the later PETs.
I *think* you need:
kernal-4.901465-22.bin
basic-4-b000.901465-23.bin
basic-4-c000.901465-20.bin
basic-4-d000.901465-21.bin
and possibly one other that I don't see (901465-29 or equivalent). I
can't remember what's in the E000-EFFF space. The best thing to do is
look at the ROMs you have, see what the numbers are, and try to match
them. As far as I know, you can't mix parts of sets.

Hi,
a couple of days ago my Pet 2001N (the 2000 Model without
the cricklet-keys) gave up :(. See
http://www.portcommodore.com/commodore/pet/petfaq/models.html
for reference. It's the 2nd machine from top, equipped with
32k RAM. When trying to boot it puts random characters on
screen. As far as I found out this _should_ be a ROM-Problem
(could be RAM too, but I hope it's ROM as I ran a Ram-Test
successfully before the Pet died). I would like to try
replacement ROMs before I have to use one of these
replacement solutions plugging a little board into the CPU
socket and providing it's own ROM and RAM. Could somebode

I have a Smalltalk software package that is available for the cost of shipping.
This is Digitalk Smalltalk/V Windows 2.0. I purchased it in Aug 1994 (10 year rule) for a course I took. I have the complete package: manuals, disks, and box.

There were probably a lot, but I remember "Call/370", which I think was
one of the first commercial ones.

I have an Auerbach report on timesharing services which I'll try to dig
up, which gives short company histories for many of the early commercial
services. Most of the major computer companies were offering some service
by the late 60's. Part of IBM's antitrust settlement with CDC was that
CDC got IBM's service bureau operation. GE timsharing stuck around for
a while. Tymeshare was one of the earliest independents, bootstrapping
themselves and fixing tons of bugs in the GENIE code.
I also forgot to mention HPs timeshared basic and 3000 systems, also from
the very early 70s ( the 3000 being HP's 'real' timesharing machine, so
they said)

Hi Tony,
Thanks - I hadn't "turned them around" as I wanted to be sure before doing anything
that could cause more damage than may or may-not have already occured. I did recall
that some 5v DRAM's had "weird" pinouts.
Looks like the machine is zeroing RAM (causes a screenfull of '@' on apple display),
and then getting "lost" before it ever makes it to the disk ROM (or at least doesn't
turn on the drive motors) - Bad RAM would have explained that nicely (bad stack)
- I'll do some more conventional debugging to see what it is accessing and see where
that takes me.
Regards,
Dave

Just a quick note to say I am still in the process of getting rid of my
excess "treasures" :). They are listed on VCM at
http://marketplace.vintage.org/. I'll be putting stuff on for the rest
of this week at least, so it might be useful to check the site
occassionally ... or frequently :). The stuff I am putting up is mostly
for sale, and not for auction.

Hi
You see, knowledge already lost. Yes, a magnetron has a vacuum in it.
It has a filament and a plate ( with cavities in it ). While the
principles of these things can be found in books, much of the
mechanical and physical methods used to create these things is lost.
Partly because of the fact that manufactures don't tell all and
partly because no one is dealing with these kinds of things.
While it is claimed that the information is in books, there
are some feel things that rarely seem to make it into these
books. Can anyone tell me what controls the gain of a vacuum
tube ( other than someone that actually worked with these )?
Can anyone tell me how the grids must be placed for an electrometer
preamp tube and why? While we don't need these kinds of things today,
the knowledge of what makes these things work is still quite
valuable. This understanding can keep us from making mistakes
with other related problems. I can't say that these specific
things that I've mentioned will be the most important things
to remember but these are the types of tidbits that make
the difference when looking into new problem areas of the
future.
Those that understand these things will always be in demand.
Those that think they can ignore these kinds of things will
wonder why things are beyond understanding. This goes
for the entire range of things. You can't understand how
to think about things without actually thinking about things.

I'm sorry to have to bother the whole list with this. I already wrote
to cctalk-owner and got no response whatever as far as I can tell; I
figured I'd let myself try the list, once, in the hope someone is
watching there but not at the -owner address.
It seems my subscription has been "disabled due to excessive bounces".
The mail saying so includes a token that I can supposedly send back to
reenable things, but it doesn't work, probably because the list
software (a) waited ten days after disabling before telling me anything
and (b) didn't generate a newly-valid token after waiting.
The last rejection (not bounce, no matter what the message thinks - I
don't accept-and-bounce except under very unusual circumstances) was
July 3rd (not the July 6th claimed by the message, unless later
attempts came through a different host), and I got no notification
until July 13th. I replied immediately and got told the token was
invalid (with a note that they're good for only three days). I sent
the whole mess off to cctalk-owner.
Just now, a week later, I got a second notice of disablement. It
included _the very same token_, despite it now being a week older. (It
still doesn't work.)
Today's notice of disablement and the response to my reenablement
attempt are quoted below, after my signature. Does anyone know what's
wrong here and whom I need to nudge to get it fixed? As I said, I've
already tried cctalk-owner. (Obviously, I won't see on-list replies
here; direct, or at least copy to me, would be needed for me to get
it.) I can dig up copies of last week's notice and response too, if
desired.

My new classic computer room is quickly filling up
and I need to clear out some space. In my quest to
find a working Dec VT52, I have acquired several dead
or semi-dead ones that I don't want to spend the time
to troubleshoot right now. I also have a VT61 that
powers up to a flashing "block style" cursor. I have
not attempted to connect it to the PDP-11/34 because
I do not have my 11/34 set up for a 20mA connection.
If anyone would like a VT52 or the VT61, let me know.
I have a minimal amount of money in these ($30 to
$50 each) and would be willing to sell them for that
price. I've been watching eBay for 6 months and have
only seen one of these types of terminals on there.
For those of you who aren't familiar with them, they
were commonly used on DEC systems (PDP-8 and PDP-11)
back in the mid-1970s and later.
I have two or three VT52s and the VT61 that I'm wanting
to get rid of. The VT61 seems to be quite uncommon.
I can't find much about it on Google. It had more
features than the VT52 and I think did "full screen"
processing, but I'm not sure.

Can't resist. This is not really in response to your
question, but at least on-topic.
In the late '80s, I shared an office with 3 other grad
students. One had a Mac SE/30 and was ahead of the rest of us in
learning the internet. He got the serial line connection to the
building Unix box run into our office, discovered how to ftp files
>from internet sites, D/L over serial to the macs, decompress, etc.
One night around midnight (when the rest of us were asleep),
he discovered a site with a bunch of sound clips from movies, and
software to substitute the clips for system beep, startup chime, etc.
He went to work, and got his box all set up the way he wanted.
Next morning, I came in long before he was up, and fired up
his machine to do something on it. Instead of <Beeeeep!> it said "My
GOD! It's full of *STARS*! <opening strains of Also Sprach
Zarathustra>".
Oh, verrry nice. I explored the new directory, discovering
eventually clips from "Alien" among quite a few others. I *also*
discovered the graphical sound-clip editor that came with the package.
Hmmm. I set to work.
An hour or so later, the owner of the machine walked in, a
bit bleary-eyed but looking smugger than anyone I have ever seen
before or since. "Hey, guys", he chirped, "I found some new software.
Wait'll you see!" Sitting down at his desk, he gave us all another
smug look, flipped the switch and leaned back in his chair as the
disk spun up. "What?" we said, our best innocent looks plastered
across our faces, "a new startup screen or something?" "You'll
see..." came the response.
The computer finally piped up, "My GOD! It's full of <click>
*..SH1T..* <click> <opening strains of Also Sprach Zarathustra>". It
turns out Sigourney Weaver's voice (as in Alien), if
frequency-shifted down about half an octave, is almost a dead ringer
for Keir Dullea's (as in 2001).
Mr. Smug's head snapped around in the fastest double-take
I've ever seen. "WHAT!" Then realization set in.. "You guys...."
He cleaned up the <click>s and kept the startup sound for
months, though.

able to help with basic faultfinding .
By the way Jules - Dragon diagrams are available from the Dragonuser group.

Hi all,
I have come into possession of a Dragon Data Beta (aka. The ?2500
business machine) prototype main board. The sad news is that
appears to be dead. Is there anyone out there who could possibly
help in getting this beastie back into life?? (If it ever worked)
Serious reverse engineering and electronic skills required! I've
had a poke about with an oscilloscope and it is clocking OK and
there is life on the data buses.
I have uploaded a few pics into the photos section.
For those interested it appears to have the following features:
? 256 K RAM
? Twin 6809E's clocked at 1.8Mhz
? Onboard Floppy controller (3.5" Single sided drives)
? Onboard RS232
? Optical interface
? External Keyboard (no keyboard L )
? Unkown DIN connector - Mouse? Light Pen??
? No built in Drag 64 mode! Only an OS-9 boot ROM (ROM dumps
available).
Simon Hardy is also holding (most of) a Dragon Data Alpha (aka
Professional) prototype for me. More info on this in the coming
months when we can actually get a power supply attached.

Hello, all:
I was at VCFe yesterday and I have to say that the speakers and
demonstrations were great. Sellam did a fantastic job and where the event
was located at the Sun facilities worked out perfectly. One demo that I
missed was the ARPANET dial-up simulation which wasn't there when I left at
3:30.
Anyway, this demo brings-up an interesting question. What kind of dial-up
systems existed in the 70's before consumer-oriented services like
CompuServe? I remember the DowJones and CompuServe sign-up packs at
RadioShack in maybe 1979 (I joined CIS in 1988. I even remember my ID:
70153,3367). I also remember in high school (around 1983) using a DECwriter
to dial into the timesharing computer (at 300 baud; I don't know the host
system) at one of the local universities.
Just curious. Thanks.

Hi
When I was at Intel, years ago, Litrtronix just came out
with one of those four letter LED display modules. At the time,
I had a 8741 in my desk drawer. I decided to make a random
four letter word display. Between me and another fellow, we had
about 15 or so good ones. Then we got help from this lady that
worked as a tech writer. She brought the list to over 50.
She calimed it was because she majored in English. I used
the minimum of parts. As I recall, the uP used a coil for the
frequency reference, powersupply for 5v, the display, a couple
of capacitors, the display and the uP.

Hello,
Having recently acquired some 6100's (I know they're
lesser than the 6120), I thought I'd try a PDP-8
project (I remember seeing these, but never got to
play with one.)
Ohio Scientific had a board--the 560Z--which contained
a 6100, a 6502, and a Z-80. The 6502 was
"microprogrammed" to emulate the PDP-8 IOT codes, and
OSI claimed that it was fully compatible. Has anyone
played with one of these suckers? How good was the
emulation? Does anyone have any info on the
schematics of that board, or the 6502 firmware? Or,
does anyone have an unused 560Z, working or not,
they'd be willing to part with?
I'm also aware of the SBC6120; I plan to order one of
these soon.
Thanks,
Dave

Anyone else going to the DARPA Grand Challenge Conference on Saturday,
August 14th? Aside from the fact that a number of lightweights
(including CMU Robotics) entered last year and are presumed to enter
again this year, I think it would be totally cool to have a robotic
vehicle powered by classic computers :)!
A ton of information if you use Google, but the main site is:
http://www.grandchallenge.org/
p.s. - The site doesn't work with Netscape 4.73 but works fine with
(ugh) IE.
I will be leaving at the end of the week for
a couple of weeks in the UK, mostly London and
surroundings, but with a few days planned in
Manchester and York.
I am planning to visit Bletchley Park and the
Babbage exhibit at the London Science Museum.
I have heard that the Manchester Baby replica
at the Manchester Museum of Science and Industry
is run weekly (or was at one time). I couldn't
find any mention of it on the museum's website.
Does anyone know the current status and schedule?
Any pointers to other exhibits or locations that
are a must-see?

Does anybody, by any chance, have a copy of the processor technology
"Simu-cisor" program? It is a program for testing a Persci drive that
exactly simulated the Persci factory drive exerciser hardware using a PT
Helios disk controller. It was distributed on audio cassette tape, not
disk, and it's tape name was "SIMU". It was only a dealer/service center
item, it was not normally distributed to end-users.
If you have this, please contact me (Watzman(a)neo.rr.com).
