The actual sectors on the CD-ROM are *always* really 2048-byte sectors.
Setting a CD-ROM reader to 512 bytes/sector just splits each real sector
into four. And many SCSI CD-ROM drives will gladly do this via a SCSI
mode select command (though not all VAXen issue the command, nor do all
drives pay attention to it!) and with some you can do it with physica
jumpers instead (or also.)
(Actually, I'm reluctant to call the information on the CD as "physical
sectors" since really the data and error correction information are interleaved
and spread out over the spiral, so that a scratch in one place won't
ruin all chances of recovering the data via ECC. The point is, a CD-ROM
is a bunch of blocks, just as a hard drive is.)
At write-time, all CD-writing software that I know of does things in terms
of 2048-byte sectors. Even the CD-writing software that runs under VMS
(for example, "cdwrite" and "cdrecord".)
If you're really bored you can learn how to do mode page editing on SCSI
drives yourself. I learned it a couple of years back when I got a boatload
of Micropolis 1.6Gig drives that had been set for 520-byte sectors and
wanted to use them in a more "normal" 512-byte mode. Since then the
skill has come in handy to connect modern, fast, and "large" (i.e. 9
Gbytes or larger) SCSI drives onto systems that don't deal with drives
that large. Just go in, edit the disk capacity mode page, and you've
got a smaller than 1 Gig drive that never has to seek very far :-).

Sure enough, got this on my mail server this morning:

It's certainly spreading fast, I've already received three corrupt messages.
Two of them came from other list servers (not this one) that I belong to and
one came from a friend.
Fortunately, I don't think this one is too distructive...

I have some IBM PC's to be disposed of, and I was planning to try and grab
a few of the full height floppy drives before they go to the campus
recycling center. Does anyone have a need for something from a PC, and
I do mean PC, the model before XT's.. Or does someone want to trade
something for a full height floppy drive. If so, let me know and I'll
see what I can do. Small things that might look interesting in a display
case would certainly interest me...
There are monitors as well, but if any work they probably have a lot of
screen burn, and arent worth saving. There is also one AT, but I doubt
anyone would offer enough to make me attempt to acquire it and ship it.
This stuff is at the University of Minnesota, Minneapolis.

Ok, so a couple of people have pointed out that the Plextor's support 512

So my question is can I use it to write a bootable disk image? Has anyone

There was no 16-265k logic board. There was a 16-64k and a 64-256k
What is the world coming to when collectors are having trouble locating

Yep, in there from the beginning.... maybe for multiple instances of cosmacs
'linked' to each other or at least as a few depositable c++ classes that can
be that generic engine.. But I didn't consider the "Load List" idea for
[all] individually specified ram and rom blocks to define a 'complete

additional 'hardware' thrown in (uart, parallel interface( probabbly

I'm reviewing the CDP1854 uart specs and a UT21 rom listing now and will add
it shortly. I need UT4! ( and UT3, etc... )

I just noticed that there is a card punch machine available here in

to the exact model, but its one of the 'old' ones, ie, its definitely
not the one with the LED display in the keyboard.
Anyways, if you want it you would probably have to pick it up next week before
it goes to the recycling center. And you would have to let them know
you want it, and arrange for a time to pick it up.

Hello all at classiccmp!!!
I'm, looking to pick up an older vax system, possibly a microvax. I'm
interested in ANY smaller main or minicomputer. We have some extra space in
teh Computer Club room at our University. We don't have much as far as
usable stuff goes ( a Pentium 75 Intel Box ). I would REALLY love to find a
uVax to setup and possibly host a server for classic computers for our ACM
Chapter, which could really use a project like this, since we are newly
formed.
Thanks!

Cripes, what a weekend! I went out Friday and the first thing I found
was a huge Helium Neon laser. It's a Spectra Physics 125 and the thing is
over six feet long! Also picked that National Semiconductor Multibus
computer that I told everyone about. Also picked up a Fluke 1722, a HP 9816
computer and a big box of 8mm computer tapes on the same day.
Then went to an auction of space stuff with a friend of mine on
Saturday. Big mistake! We've been moving stuff ever since. I've been
leaving by 6:30 AM and not getting home till close till midnight. We ended
up with four large work benches, 30 feet of 12 foot pallet racking and
about 35 pallets of stuff! We got some cool stuff though, a complete Apple
II, an Apple III with an external disk drive, two Olympia ETX-II computers,
a Terak computer, a pile of HP terminals, a complete DEC Rainbow and more.
Also got a a VERY complete HP 1000 including a 7905 disk drive with the
disk pack still in it. Also found an entire gaylord of manuals for it. And
that's just the computer stuff. Also got all kinds of electronics parts,
test equipment and space stuff. Even got parts from a lunar lander and a
gyro from a Saturn V. Also got a UV spectrometer. Way Cool! Other goodies
include 50+ factory software tapes for the HP 9845, a strange old HP MODEM,
nine HP 85 interfaces and a blue Intel paper tape reader to go with the
rest of my Intel MDS system.
Joe
PS does anyone have any instructions or a catalog listing or other
information for a Tektronix J20 (or 7J20?) Photo-Spectrometer????? It's a
plug-in for the Tektronix 7000 series scope mainframes. We got all three
pieces of the electronics for it but didn't get the lense for it. It might
be in the stuff but we don't know what it looks like.

I haven't used a Plextor writer, but I see no reason for it not to work.
Any writer can write a bootable image. I've done so with my Yamahas and
Teac. Writing is always done with 2048-byte blocks; the sectors in the
images are always 2048 bytes (well, for Mode 1 data, anyway). Setting a
CD-ROM to read in 512-byte blocks just makes it deliver the data in chunks
that size, it has nothing to do with the physical blocksize on the CD.

Yes, those are cool. They can also be used with the HP 75, HP 71 and HP

Now those are unusual. I have two volumes but I've never been able to
find any more of them. Where did you find them?
Joe
Ok, perhaps a simple question.
Is there anyway, by inspection of the case, to identify whether or not a
CD-ROM drive will read 512byte records? If not, is there a list of "known"
models that can?

The key on a restored care is id the battery a new white

I happen to agree. While im not into museum restoration
myself having things work is important and I do try to use
exact parts often due to my junkbox depth as old or older
than original. While static displays have a place working
examples of the real or by replication are far more interesting.
Computing is not only about machines. It's about software
and the people that designed, built and supported them as well.

I have a bunch of older Panasonic MX3501s that work fine and recently bought
a

Thats a Panasonic (aka Masushita or some such).
Likely the best giveaway is any drive with a jumper for selecting block
size or slower than 4x plus SCSI is likely a winner.

It's about the same size and shape as a half height 5 1/4" hard drive

I don't know anything about it other than the obvious. I haven't had a
chance to look at it closely. It looks like a model 8510. It has one 8"
floppy drive and the monitor. It has two serial ports and each has
connectors for DTE, DCE or current loop connections. It has a monitor port,
a composite video port, a keyboard connector and a connector for additional
drives. I'm missing the cable that connects the monitor to the CPU and I'm
missing the keyboard. (Unless it turns up in the rest of the stuff.)
I'm posting pictures of it at
"www.intellistar.net/~rigdonj/terak/terak-f.jpg" and
"www.intellistar.net/~rigdonj/terak/terak-b.jpg".

A spare door and part of the RADAR altimeter. We've already been
offered VERY serious money for the door. In fact, more than enough to pay
for the whole load. Oh, also got sections of the tunnels that were
supposed to connect the different modules of Skylab. They remind me of
those tubes used on the gerbil and hmaster habitats!

Wonderfull Allison, thanks! There's a win-32 console binary (it's small)
for 95/98/NT or a single .cpp source file that shouldn't be too hard to
recompile anywhere else.
Dump machine code in with the m! command (for ex: " m! 0 1525c4" will dump
INC (r5); DEC (r5); NOP into 'ram' starting at address 0 (A write cursor
allows continuations in entry, another "m! c4c4c4" will write 3 NOP's
starting a address 3 using the above example) and then three 't' commands
will single-step execute the instructions (or a single "t 3" would have
too). 'r' dumps registers at any point. and "m? address [count]" looks at
memory.
Thanks for the help!

They are still available occasionally at my local Volunteers Of America
outlet - routinely $5 to $7, keyboard extra. I have one or two including
one that is still performing its original duties from 1983 - a display
terminal for a NorthWest Instruments 68000 bus analyzer. We threw a
defective MFM drive on it (bad platter giving us reduced capacity) and
slapped it and the NW box into a gutted VAX-11/725 case. It was very handy
to wheel up to a test board and plug in... the mono monitor and full-sized
keyboard fit on top of the former VAX without falling off.

Just noticed a new article in the Milwaukee Journal Sentinel. A new
recycling program started 2 weeks ago, and already they have quite
a few computers (well, duh!). Anyways, here is a link, you can
read teh article, and if you're in wisconsin, maybe you might
want to start paying them a visit occasionally, and geting them used
to interacting with collectors, maybe even talk them into saving
certain kinds of hardware... who knows what you could accomplish
with a brand new program like that.

A good number of the emulator (simulator?) authors are a bit afraid
that releasing their current source code would require that they
support it. I'm of the other opinion - if they release their
current source code (I don't care if it's GPL or not GPL, I do
*not* want to get into that religious war!) then others will support
it.
What's really encouraging is that several of the authors of the DECUS
freeware in the archives have wandered across the collection and told
me that they appreciate seeing software that they used or wrote
themselves, sometimes 30 or more years ago.
> TOPS-10 and TOPS-20 software is available online thanks to Tim Shoppa

You're welcome :-). It's nice to see that at least I - and both the
anonymous and not-so-anonymous donors mentioned at the archive home
page,
http://pdp-10.trailing-edge.com/
- come off as the good guys. We're really trying. I've seen some
emulator progress mentioned here as a result of the sources being
available and browsable, and that's a Good Thing. So far
several hundred people have visited the archive site and downloaded
or browsed through the software available, and that's a Good Thing
too.

It really breaks my heart and pains me that so much software
is out there just rotting away. Some of the current holders of the
tapes don't understand that the tapes *are* still readable (sure,
not everyone has 9-track and 7-track drives anymore, and not
everyone has the ability to read and decode TOPS-10 BACKUP or
TOPS-20 DUMPER tapes, but I do!), others don't understand that there
is a wide interest in the software.
There are some other organizations - such as computer museums - that
probably don't understand the value of the tapes or disks
they currently have in their collection. Many of these museums
have members/volunteers that read this newsgroup, and I hope that
those readers pay attemtion to my plea below.
Thus I'll repeat my plea:
If anyone has any PDP-10 software covered by the DEC 36-bit hobbyist
license, please get it to me. I'll pay shipping both ways, and I'm
an expert at archiving old data. Your tapes will be properly cared
for, carefully read, and returned. If you want, you'll be thanked
on the archive page for the stuff you provide, or if you prefer you
can remain anonymous. Just don't let the software rot away!
The best reference I can give is what I've done so far. Just
look at
http://pdp-10.trailing-edge.com/
and you'll find hundreds of megabytes of PDP-10 software, preserved in
both *exact* tape or disk image form and as browsable, human-readable
files. Both commercial software covered by the DEC 36-bit hobbyist
license and the DECUS 10- and 20- freeware collections are available
there.

My Equipment recycler got in a couple of pieces of equipment that He thought
the group might be interested in.
1) IBM 3370 Head of string in good condition with an ADIC? custom controller.
2)"Ultimate" Pick machine from about 1980. I think this is a PDP 11 based
machine. This is an a rack with a large Hard Drive and 1/2" tape.
Both are operational. Both would need freight shipment. We are experienced in
shipping large units.
If anyone is interested please contact me off list at whoagiii(a)aol.com.

I'm starting to hate SCSI :^)
Possible problems:
2GB HD
VAX Hobbyist V2 CD-ROM
SCSI Cable
Definite problem:
The way the switches were set on the CD-ROM. The only thing I can think of
is that somehow those switches got scrambled, not only was there the
512/2048-byte block problem I was fighting last night, but there were
apparently termination problems. Anyway I've not got OpenVMS V7.1 loaded
on a 1GB HD that came out of a Super Computer and am configuring it.

Hello All,
I've got two VLCs, I'm running them both headless. They are connected to S1
and S2 of a VT340 terminal. One of them "loses" the terminal sometimes. If
try typing nothing is echoed although I can still send stuff to the serial
port from a process and it displays. Sometimes I can "fix" it by breaking
to the chevron and then typing 'c' (continue). This happens on both VMS and
NetBSD so I don't think it is a driver problem.
The other VLC doesn't have any issues like this at all.
The VLC that has no issues has Firmware 1.5, the one that has issues has
Firmware 1.3. I'm wondering if there is a way to flash the firmware? I've
got an EPROM programmer but I don't know if there are is anything else I
need to do.

>Is it possible to use bigger than 1GB as system ? Don't know ...
Yes you can buld bigger than 1gb. the problem if the VLC isn't aware
was that if the system crashes under VMS it would use the BOOT ROM
driver for the SCSI disk. For many of the 3100 series systems this
meant if you used a disk larger than 1.07gb and it crashed it would
over write the area that was in the 1st 1gb. if it never crashed it would
run fine as the VMS driver that is loaded was large disk aware. Later
systems that were SCSI had this fixed but I don't know about this one.
The easy fix is to build a system using boud volumes with the smaller
being under 1gb. Also reduce the swap to 5k blocks and put page
and swap files on secondary drive where they can be any size.
FYI: I only have one VAX that now has a 1gb disk, this has never been
a problem for me and I run a lot of stuff in rather small disks.

Not that I know of for VAX.

Not surprized. Enjoy!

By 'Almost,' I meant just for postage ($3.20 Priority Mail).
I have, still with the tape in its shrink-wrap, the 'Personal Application
Kit' for the NEC PC-8201A portable. Got the manual with it as well.
First one with an offer to cover postage gets it!
Thanks.

If you look, you'll find that video capture devices range from cheap and
lo-res (< $100 and about 150 pixels across) to mid-range ($200 to $300,
about 250 to 300 pixels across) to expensive ($300+, about 300 to 640 (or
more?) pixels across).
There appear to be 4 basic interfaces:
1) USB
2) parallel port
3) backplane (i.e., card plugs into your system)
4) FireWire
I found one low cost device in the mid-range performance category,
made by Belkin. It's a USB device and cost me about $89. Not counting the
cable, it's about the size of a pack of gum. Inputs: SVHS and regular
RCA jack. The included software uses your sound card to get the audio.
It captures to MPEG format.
I'm not a video expert...but the quality seems acceptable to me.

Sorry for the repost but I forgot the subject line.
My Equipment recycler got in a couple of pieces of equipment that he thought
the group might be interested in.
1) IBM 3370 Head of string in very good condition with an ADIC? custom
controller.
2) "Ultimate" Pick machine from about 1980. I think this is a PDP 11 based
machine. This is an a rack with a large Hard Drive and 1/2" tape.
I haven't seen either but if there is any interest I will get more info.

Hi,
I have a pair of 851s in a nice case with power supply.
They are attached to a Cromemco 16FDC in an IMSAI box
with a Cromemco ZPU and an Expandoram 64K board. I'm
using the ROM enable on the 16FDC to drive the phantom
line. There is a reason for these details...
Here is the problem:
#1 Power up the drives by themselves:
At the drives:
5 volt line reads 4.9
-5 volt line reads -4.9
24 volt line reads 23.9
#2 Power up the IMSAI box:
At the drives:
5 volt line reads 1.2
-5 volt line reads -0.9
24 volt line reads 2.6
and (needless to say) the drives don't work. The Cromemco
ROM monitor gives all sorts of errors trying to access them.
#3 Power off the IMSAI box:
(Same as #1)
#4 Power on the IMSAI box again:
At the drives:
5 volt line reads 5.0
-5 volt line reads -5.0
24 volt line reads 24.0
and the drives work fine.
What gives? Does this make sense to anybody out there?
Thanks to the people who have responded. There is no suffix to the board
number. M8189, that's it. I've looked really closely at the soldering of the
UART socket. It has the same flow as the rest of the components, so I still
think it was manufactured this way. I powered it up tonight and determined
that the daughter card is the console port. I connected a terminal and it
works as you would expect. The firmware seems to be standard 11/23+ 1.0
firmware. I think I'll just by a 6402 UART and replace the daughter card.
Thanks again,
Bill
Pretty funny.... Or I guess synchronistic, I guess. I just got my 1802
simulator past the first milepost tonight (It's two days old). It'll
process all the Cosmac's instruction's, show registers, and deposit to and
examine ram.
I could use a few beta testers if you happen to know cosmac machine code.
it's at:
http://users.leading.net/~dogas/classiccmp/cosmac/cosmac.htm
Tomorrow night, I'll add arbitrary ram block saves and loads from disk and a
mini assember if things go fast. Eventally, I'll add a nice GUI to it and
clean up the code that I'm muddling around with.
Cheers

Hi all,
Just received my previously-mentioned Raymond Scott "Manhattan Research"
CD-Set/Book and it's incredible. Wow.
On-topic, it has the soundtrack to an industrial film for the MT/ST from
1967. In there is Jim Henson's voice announcing, "Used systematically
throughout an office, these two pieces of IBM equipment alone have
increased people's productivity by 50%."
If anyone is interested in hearing it, maybe I could post a couple of
snippets as mp3 files or something...just let me know.
Cheers,
Aaron
Real Sun 3/280 rack. Its probably more useful as a generic 19in rack than
it is as a Sun3/280. Complete with fans and power distribution center
(not real useful either -- requires 30A outlet). Also includes the 3/280
chassis/cardcage.
Also, you get two Fuji Eagles (SMD). You must take these with the rack
since 1) I have no where else to put them and 2) I have no where else to
put them. (And don't forget 3) They're damned hard to lift straight off
the floor.)
I'll throw in the SMD controllers if you like. I'm not sure if I still
have the original /280 boards, but I could probably find a /260 system
board (same exact things) for you if you really really want to bring up
the system. (Yes, it does boot off the Eagles. I don't recommend it.
Especially in the Arizona summer.) SMD cables included (but you get to
figure out the proper way to connect them).
All this for free (or best offer!). The condition is that you get to pick
them up from my home in Peoria, Arizona. And you have to have a truck
thats big enough to haul them. (I hauled it home in a 1979 Chevy
Suburban. Its not _too_ bad. Not a job for the for the small and weak,
though.)
Dimensions for reference: 24in x 36in x 78in. I'm not even going to guess
on the weight. You probably want to haul the Eagles in the proper way if
you want them to work when you're done.
I even have pictures, for the patient: http://www.auk.cx/sun3/pics/280/
(Monitor and keyboard not included.)
Please forward this to whoever you think might be interested. I don't
want to keep it in my garage over the summer. It gets into and beyond the
120s out there.

Anybody know where I can find an AC adapter for a Thinkpad 720,
or alternately, anyone who has older 486 Thinkpad(s) for sale *cheap* ?
Thanks.

Well if someone else doesn't drop a box of stuff on you I have
Quest TB for the 1802 somewhere safe. I can zap a copy of
the dump. But you can't have the paper tape!

George Currie was the lucky(?) claimant, though Doug Salot came in a close
second.
Thanks, folks!

VAXen with SCSI seem for reasons I've forgotten to be always set as host at
6
so a device at 0-5 and 7 are ok. It wasn't until I'd seen PC SCSI that i'd
ever seen
a host at 7!

It hauls! Check on this, I think that machime may not have the problem but
older SCSI vaxen have a limit of 1.07gb for the boot disk. Has to do with
how VMS uses the boot rom driver if it has to do a core dump on crash.
I run a VS3100M76 (7.8vup) and DW runs really well on it.

I've got two VAX VS4000/VLC workstations, both with 24MB, one with a disk
and one without.
One takes two or three minutes to perform the memory test at power on and
the other takes maybe 20 - 30 seconds. Any idea what could cause this
descrepancy?

Thanks to everyone for the interesting discussion on lead-acid batteries.
I seem to have gotten lucky with my new Portable. After two days of
charging at 300 mA, the Portable fires right up, and loads System 7.5 from
the 40 meg internal HD. The system also has the Apple 3 MB RAM expansion
installed, for a total of 4 MB RAM. No backlighting, though. The only side
effect of being long-dead seems to be a fairly fast drain on the battery
when the system is off and not plugged in to the adapter; I'll have to
experiment to see if this is due to the system going into sleep mode rather
than powering down completely, or whether the battery isn't holding it's
charge.
I'm still hunting for a Portable AC adapter and/or replacement battery
locally; if I can't find one, I may contact one of the list members who
indicated they may have one for sale or trade. Thanks to all.
Regards,
Mark Gregory
