Even worse is a rack-mount dual BA23. I used to have to pull all the
cards out and reseat them on one system. The quad-width cards had locks,
but the dual-width didn't, and I couldn't easily get to the dual-width
cards to properly reseat them with the quad-width cards in place. I
really like the BA213 and BA440. I have a 4000/500 in a BA440 at home.

Yes, indeed. All because of licensing costs. The 8820 is their
slowest system and all it does is run that one piece of software.
Never mind the environmental and service costs are more than a
new system and license.

I'm rebuilding an RM03 head stack (I have two crashed drives, making one
good one from the two), and I got a problem here...
Drive one has all of the heads bad except for platter 2, head 1, and
surface 3, head two. (That is, I have one good UP head, and one good DOWN
head.)
Drive two has all of the heads good, except for the heads for platter 1.
That is, I have both the UP and DOWN heads for the topmost platter dead.
The problem is, the good UP head from the first drive is the servo head,
apparently - The pigtails for this head come out on the opposite side from
the others, and it has a double-ended connection. Can this head be used
as a normal data head anyway? The pinout looks the same, except that it
has two endings, both of which look alike...
Can someone look at the RM03 prints and find this out for me? This is my
only good UP head, so if I roach it, I'm done for.
PS: Ripping the drive apart and getting the head stack out to play with
was somewhat easier than it looked like; All I had to do was get the big
magnet out of the back, have someone hold the logic cage while I undid the
drive head pigtails, undo the track 0 microswitch, disconnect the big coil
at the end of the head assembly, and pull the whole mess out the back of
the drive.
Oh, and I'll have to take pictures of the crashed heads later; They're
really impressive! The original top head for the second drive is
COMPLETELY GONE. I have both the head and the platter it crashed onto
stored upstairs to take pictures of as soon as the camera works again.
I was rummaging in the attic looking for my IBM 1130 listings, and came
across this Interdata 7/32 C Maintenance Manual. It includes detailed
schematics of the CPU, and the microcode listing. Is anyone interested in
scanning or copying this?

A good book was written about this back in the late 80s by
the bloke who taught us about digital design. I forget the title,
but the author is Peter Thewlis and the book was published by
the Oxford University Press. Takes you all the way from the
basics of how to build various flip-flops to how to build
registers and an ALU. Excellent fun :)

Does anyone know how to take the rolling feet off a BA215? Its really
straightforward on the BA213 (I assume the same for the BA440) but the
BA215 has recessed hex head screws and I can't get to them. I was wondering
if there was some "preliminary" step that exposed them.

I accidentally deleted the message before I read it completely, so
I don't know what you said after commenting about the VUPs rating
for the 7650, but the 7650 is about 155 VUPs, not 175, according
the table I got from DEC. The 7610 is 35 VUPs, and each processor
adds 30VUPs. You lose the rest due to overhead.

I had a Mac II, which used a 68881. I remember the 68882 being sold by
some people as a speed-up for the Mac II.
I bought a 68851 MMU so I could run A/UX on my Mac II. The 68851 added
functionality necessary for A/UX but did slow down memory access slightly.

I don't think an 11/34 or similar would come anywhere close to a 486DX2-66
in terms of processor speed. More like a slow 286. The real advantage of
a mini was the architecture, which was designed to reap the benefit of
multiple intelligent DMA subsystems and perhaps multiple busses. The same
is true now, comparing expensive SGI kit with fast Pentiums -- you only see
the advantage on specific tasks, like certain kinds of rendering.
> Any suggestions for a fair race?
Something that reflects the sort of use a mini would be put to; something
with multiuple users or at least multiple processes, and a healthy mix of
I/O. A Dhrystone test is definitely not what I'm thinking of :-)

I was wondering about this! In all honesty I don't see any reason to go
this low level, by doing this you're making it less portable. Ideally you
want something like a stripped Linux or QNX system sitting on top of the
hardware, with the system emulator sitting on top of that. If you want to
avoid UNIX altogether, just take simh, and set it up so that it's started
when the system boots, and you boot all the way up to the OS of your choice.
Go one step further and hack simh so that if you shutdown the OS running on
top of simh, that it shuts down the host OS.
If you want to do hardware, go with FPGA's and reimplement the CPU and
controllers like Neil Franklin is trying to do with the PDP-10. The tricky
part here of course being the disk and tape controllers (unless you want
to write your own device drivers).

They look to contain HSC-specific cards. They sorta resemble
VAX-11/750 cards in size and card-edge connectors.

The ones I've seen have been regular SMD (0.5" pitch) devices which are not
too hard to do with hot air, or are ordinary DIL (0.1" pitch). The last
one I soldered was a DIL chip.
Timing might be a problem; I have almost no idea what access time DIMMs are
supposed to be but I expect it's faster than SIMMs. SIMMs are usually in
the 60ns-120ns range, and it's not too hard to get FLASH or EPROM in that
range too. You'd just need to demultiplex the addresses (latch the
addresses presented on the first part of the memory cycle). Of course,
modern motherboards use DIMMs.

We have HSC95 controllers. I haven't looked inside as they are 24x7,
but in the next month I'll be taking two of them out of service (and
leaving two just to serve some 3480 and 9-track tape drives). Is the
OS RT-11?

There's a T-11 on the RQDX disk controllers. I've also been involved in

Hey all,
Sorry bout the spam (and sorry if you already know about this) but I figured you folks might want to know to watch out for a new Code Red-esque worm that's running rampant...below is from SlashDot. http://slashdot.org/articles/01/09/18/151203.shtml

New (More) Annoying Microsoft Worm Hits Net
Posted by CmdrTaco on Tuesday September 18, @10:10AM
>from the what-a-pain-in-the-arse dept.
A new worm seems to be running rampant Unlike Code Red, it attempts to hit boxes with many different exploits (including what looks like an attempt to exploit boxes still rooted by Code Red). It looks like each IP tries 16 attempts on its neighbors. There is also a new mail worm mailing WAV files or something with bits of what appears to be the registry... it may or may not be related. Got any words on this? Shut down those windows boxes and stop opening attachments. And make that 21. Got another one while writing this story. All my hits are coming from 208.n.n.n (where I am) I'm sure it'll keep moving to nearby boxes.
Here are examples of the requests it's sending:
GET /scripts/..%%35%63../winnt/system32/cmd.exe?/c+dir
GET /msadc/..%255c../..%255c../..%255c/..%c1%1c../..%c1%1c../ ..%c1%1c../winnt/system32/cmd.exe?/c+dir
GET /_vti_bin/..%255c../..%255c../..%255c../winnt/system32/cmd.exe?/c+dir
While writing this story I was hit a total of 4 times, 16 GET attempts per attack. In only 4 minutes. Also of interest, My desktop has now been hit about 500 times today, all from 208.x.x.x IPs. This might be really bad. I still haven't read anything about this anywhere else, so you heard it here first ;)
Update: Web servers compromised by this worm apparently attach a "readme.eml" to all web pages served... and due to a bug in IE5, it will automatically execute the file! Yay Internet Explorer!
It came in last week, I ordered it from Kendall electric. It's an Ideal
Industries Crimpmaster. I was a little disappointed to find that it was
made in Taiwan. Oh well, at least they are allies.
I bought the connectors to go along with it too. I got home, promptly
cut off the filed down standard RJ11 connector off of one end of my
cable. THEN, I tried putting a new connector into the crimper.... I
couldn't figure out how the dumb thing was supposed to work! I was
thinking GREAT, I just dumped 70 bucks into a specialized tool I can't
seem to use. I checked part numbers several times. Turns out the MMJ
die set was in wrong.... they misassembled it at the factory. It worked
fine once I straightened it out :-) Now I have a proper cable :-)
Maybe sometime soon I can start messing around with the Vax again....
still need to break into VMS.

DEC used embedded PDP-11 processors in many different places. There's
the console for some of the VAX systems, and I've read some of the
DECsystem-10 or DECSYSTEM-20 systems used a PDP-11 as a console system.
Other uses of the PDP-11 that I know of are the HSCxx controllers and
some of the printers. Where else did the PDP-11 get embedded? I know
the HSZxx/HSDxx/HSJxx controllers used an Intel i960 processor, so
there's no PDP-11 there.
And speaking of the HSCxx controllers, are the PDP-11 controllers
customized or is there a standard QBUS or UNIBUS system in there?

APL/1130... Lord, that brings back a couple of memories. FWIW, the language
is very similar to APL/360. The nasty part was the special symbols. The
console keyboard (basically a 029 keyboard) was mapped into three shift
states (3 symbols per keycap) with the shift state being indicated by banks
of front panel lights.
IIRC, make sure to make lots of copies of the APLIPL card as my experience
was that the reader/punch would occasionally munch it.
Also IIRC, the correct name for the IPL card is a "Cold Start" card.

Hi
Garbage day tommorow and I will be scrapping more stuff I have accumulated

This all going to charity (they probably wont want this) or garbage in about
24 hours or pick it up if you want it.
I dont wanna start packing -- you have to have someone to pick this up.
I know this is quite a long shot since I am in Montreal, Canada but who
knows...
A shame because most was cleaned and is working....most of this is stuff I
have more than one of or just no space for...
I anticipate more stuff getting junked so anybody with a large car or van
that can pass by here can probably fill it up.
MPS801 Commodore printer
Commodore 1525 printer
DEC LA50 printer
TRS80 model II "8" floppy expansion box" with no drives
Compaq portable II
TI994a beige version
TI994a black version
Several MAC Plus and SE (no se-30s)
Apple IIc
Several C64 and Apple books some in french
Some C64s and 1541 drives
Untested 1084S monitor
Stuff I cant see myself throwing in garbage but would like to see go to a
good home : several Atari STs and Amiga 500s...

I remember an early brochure for the 11/750 talking about how it would be
easy to load custom microcode to emulator other processors. This wasn't
in later brochures or product descriptions for the 11/750 that I've seen.

I don't think the DSSI drives have a PDP-11, but they are pseudo-CI.

Apple's refusal to document the system was one problem. Another problem
I had (that I started griping about during the A/UX 3.0 beta test) was
Apple wouldn't let the engineers support the GPi pin on the serial ports
under A/UX because not all Macs had the GPi pin. I continuously pointed
out that all Macs that could run A/UX *DID* have the GPi pin, and they
could allow this to be a configuration option. Without the GPi pin there
was no way to have secure dial-in and hardware flow control, which means
you really didn't want to have a dial-in connection on your A/UX system.
There's a lot of other ways Apple mistreated IIfx owners.

Hi,
does anybody know something about the DEC DESPO-A BNC Ethernet
Transceiver?
Its a small box (about 115*60*35 mm) with a BNC connector and a
MMJ connector on the otherside. And ther is a cable wich on one
side has the MMJ and on the other side a big black connector
(don't know the name) which I have seen at token ring MUAs only.
I haven't seen those token ring connectors for ethernet,
and no BNC connectors on token rings. So I am a little
bit confused about the purpose of these boxes. Looks like
a ethernet/tokenring bridge but I don't believe this.

Hello all,
First let me say that I hope all of you are all right, and that your lives
are as normal as possible given the recent events. I know it's hard to
think about old computers at a time like this, but I did at least want to
let you all know what was happening. Obviously, if there are any delays in
our transactions, I certainly understand ... Take care of what's important
first....
Bear in mind that these systems are school surplus. They WILL need
cleaning, and many have stickers, sticker residue, magic marker writing,
etc. They are all in good physical condition (no rust, no cracks in the
cases, etc.), but they all need to be cleaned.
Here are the final counts on the IIgs stuff... These are all tested and
working:
- Qty. 14 ROM 3 IIgs CPUs, with power cord, NO internal cards.
- Qty. 8 ROM 01 IIgs CPUs, with power cord, and memory expansion card (only
one bank full on each).
- Qty. 22 5.25" Floppy Drives, Model # A9M0107, with cable
- Qty. 23 3.5" Floppy Drives, Model # A9M0106, with cable
- Qty. 12 AppleColor RGB Monitors, Model A2M6014, with power cable AND
signal cable (see below ... more available)
- Qty. 9 mice, with ADB connector, labelled as Model # A9M0331
- Qty. 7 mice, labelled "Apple Desktop Bus", "Family # G5431"
- Qty. 3 Apple Desktop Bus keyboards with cable (see more below)
- Qty. 2 Macintosh LC II CPUs, with power cable
- Qty. 2 Macintosh Color RGB Monitors, with power AND signal cables
- Qty. 2 Apple IIc computers, with power supplies
The following are untested:
- Qty. 5 Imagewriter II printers, with power AND data cables
- Qty. 17 Apple Desktop Bus keyboards and cables
I am willing to test the remaining keyboards, and the Imagewriters if people
want them. I also can get more monitors, but again, I only want to lug them
here and test them if people want them.
Please, even if you have responded before, respond with a specific list of
what you want. Don't tell me "a complete system", because I have no idea
what that means (mouse? 1 floppy? 2 floppies? ROM version? Monitor?). BE
SPECIFIC. The two types of mice listed work with the IIgs, but I don't know
if either is "correct" in that I don't know which version shipped with the
IIgs. Because some items are limited in supply, if I get more offers than
items, I will throw names into a hat to decide who gets what. PLEASE INCLUDE
A ZIP CODE OR COUNTRY WITH YOUR RESPONSE so I can determine shipping
costs...
Once you respond with a want list, I will determine if I can fulfill it,
then weigh everything, and get a shipping quote.
In terms of money and shipment ... Payment must be in US funds, and I accept
PayPal, or Money Order (International Money Order for overseas). The cost
of each order is a minimum of $5.00 + "shipping". What this means is that a
single cable will cost at least $5.00. A complete system will cost at least
$5.00. Anything over $5.00 is up to you, bearing in mind that ALL proceeds
will be donated back to the school I got the computers from. There is no
special priority given to people who donate more money. "Shipping" includes
actual postage (USPS from Westminster, MA USA 01473), plus actual cost of
boxes and packaging (no more than $5.00, even for a complete system).
Monitors and printers will be shipped in SEPARATE boxes from CPUs. If you
come to my house to pick them up, you can "cherry-pick" for the best
cosmetic condition.
Thanks!

Good to hear there some other 1130 fans out there!
I should have added that we have ten disk cartridges with our 1130.
One is labeled "IBM Only" and we hope it's a CE disk. We didn't
find any punched card based software other than four IPL (boot) cards.
One is labeled "APLIPL" and we have an APL typeball, so we think
one of the cartridges has APL on it. However, we're a long way from
trying to spin it up to see if the disks are still readable after
what must be 20 years.
We also have the maintenance manuals and schematics, but
no diagnostic software listings. We'd be interested in getting
copies of anything you get scanned or OCR'd, Hans.
Norm is setting up a boffo website for it all. A grand
opening announcement will be coming soon!

It was a custom designed interactive TV unit, used for some test program
in Texas and I think the UK. I think it was tested in a few schools, but
I really don't know how far it went (it was probably slammed out of
existance either by cost, or more likely by Channel 1 if it was meant for
the educational market).
I don't personally know of anyone that has gotten theirs to do anything,
although I have read posts of a few people that got theirs to at least
boot to an Apple logo screen. Mine just sits (it gets a red "starting up"
light, but never gets past that to the yellow "standby" or green "on", or
even the red blinking "busted" light).
I got mine from a garage sale just recently (paid $5 for it, no remote,
no anything, just the unit)... the guy selling it said his son went off
to college, and he was getting rid of some of his "junk" he had kicking
around the house while his son wasn't there to complain... my guess is,
when the son gets home for vacation, he will be mighty pissed off (I also
got a vintage 2 foot Godzilla with working shoot out hands and flicking

I have seen them come and go on ebay, usually selling for between $10 and
$20 if you want to pick one up.

Additionlly, several models of Macs have had either SIMM or DIMM

We have several (about six or so) full boxes of fanfold, tractor feed,
printer paper, both 8.5 x 11 and 11 x 14 sizes, that are free to anybody
who wants to pick them up in Milpitas.
We have lots (a couple dozen at least - I'm too lazy to count them) "data
binders" for 11 x 14 printouts. These are the nice, heavy covers that fit
printouts on tractor feed paper and keep them clean and pristine. Also
free, in Milpitas.
We have have a printer stand for a 11 x 14 tractor feed printer, complete
with a sound proof enclosure and fan. No printer, I'm afraid, but still
free.
Contact me if you want any or all of them.

Oops, sorry about that! I was thinking about the series 48 that had
been mentioned in this thread.
Yes, a Micro 3000 is more "desktop sized", or at least the processor
is. Peripherals like disc and tape drives are in separate boxes so
it's easy to end up with a system comprising several small boxes
(e.g. a Micro 3000, a 9144 cartridge tape, and a couple of 79[45][1-9]
disc drives), and once you've got all that they can be stacked inside
a desk-side cabinet that HP used to sell for the purpose. If you look
at the cover of the September 1985 HP Journal you will see a 3000
series 37 in this sort of cabinet.
Note there are also "Micro GX", "Micro RX", and "Micro LX" models that
are usually mounted in desk-side tower cabinets that have room for a
9144-like cartridge tape drive in the top and two disc drives in the
base, and also keep the ATP/M mux panels (serial connectors) inside
the cabinet. They weigh about 70 pounds and can be moved by a single
person reasonably easily.

Some SGIs do put out a separate sync signal; some Suns do as well.
However, SGIs tend to provide separate hsync and vsync while Suns mostly
do composite sync. Moreover, they use different pins for the sync and
monitor type sense. I'm sure I posted the two pinouts to the list a while
ago.
But I've found almost all my multisync Sonys work with mu Indys and
Indigos, providing I have the relevant 13W3-3xBNC or whatever cable. I
think the only exception I've found was a Sun-badged Sony that wanted
composite sync.

"desk-sized", not "desktop". It looks sort of like one and takes up

Speaking from personal experience, you may have to un-bolt the top

Recall that Jonathan Engdahl recently announced his development
of MSCP device drivers for 2.9 BSD. That work was made possible
by the availability of a reliable simulation environment.
For this reason alone, simulators are indispensible to the
real-hardware camp, as tools for supporting the maintenance and
development of operating systems.
Furthermore, I think simulators can play a big role in
encouraging the long-term collection, retention and dissemination
of legacy software to run on either real or emulated hardware.
Norm Aleks and I just acquired an IBM 1130, and as far as I can
see, there is NO software archived out there anywhere. It's very
discouraging. You can bet that we're going to post whatever we can
get our hands on, along with the simh-based simulator I'm 75% done
with, to hopefully reawaken interest in the 1130.
That's my .4 bits worth.

> to 3 BNCs to hook up to a decent monitor that does sync on green
If you try to use a fixed frequency monitor, you must use
one that is a sync on green model monitor and that syncs at
the correct horizontal and vertical frequencies. If you can
determine which model monitor originally went to that system,
you might be able to research a DEC or HP model that syncs at
the same frequencies at ...

> some older multisync Mac monitors with the 3-BNC input might work
^^^^^^^^^....... NOT .......... ^^^^^
Sony made monitors for DEC, HP, IBM, SGI, Sun, RasterOps, Radius,
and possibly others. If a monitor has only 3-BNC inputs, it is
most probably a sync on green fixed frequency model. If it has
4-BNC inputs, it is most probably a composite sync model ( the
only exception I know of to that is a NEC model which also has
a HD15 connector in addition to the 4-BNC's ). Any other monitor
I have ever seen, other than those NEC models, that is a multisync
had 5-BNC inputs. Note however that some 5-BNC input models are
fixed frequency ( GDM-1950 and GDM-1952 come to mind ). Generally
I have found that the Sony models that have 5-BNC inputs and
rotary controls are the fixed frequency type. The models that
have 5-BNC inputs and have push button controls ( digital ) have
been multisyncs ( GDM-1971 and 2075RO come to mind ).
http://www.monitorworld.com/Monitors/sony/http://www.monitorworld.com/Monitors/radius/http://www.monitorworld.com/Monitors/radius/0322precisioncolor20.htmlhttp://www.monitorworld.com/Monitors/rasterops/http://www.monitorworld.com/Monitors/rasterops/2075ro20colorgraphicsdisplay…
Those monitors that are considered multisyncs should be able to
sync up on a horizontal scan frequency as low as, or slightly
lower than, DOS's 31.5 kHz. The really nice thing about the
5-BNC Sony models, both fixed frequency and multisyncs, is that
they auto-sense, and auto-switch sync types. So even though the
monitor has 5 BNC inputs, you can still hook up to just 3 of
them if your graphics outputs a sync on green signal, or 4 of
them if your graphics outputs a composite ( H and V on the same
line, but a separate line than R, G, or B ) sync signal. And of
course if your graphics outputs a separate sync signal ( H, V,
R, G, and B all on separate lines ) you would connect to all 5-BNC
inputs. I use my Sony multisyncs to hook up to and test my DEC
Alpha's (SOG), VAXstation 4000/60's (SOG), HP PA-RISC (SOG),
Sun's (CS), Macintosh's (CS), and of course, PC's (SS). In fact,
my multisync Sony's have worked with just about every type system
I have ever tried them on except my SGI Indy's, and that might be
because the SGI's 13W3 pin-out might not be compatible with the
13W3 to HD15 adapter I use with the Sun's? It's been very
convenient, space wise, to use one monitor to test all those type
systems, rather than have to store a different monitor for each
one.

Unfortunately, the monitor that may have been hooked up to the machine
was
nowhere to be found... and this being my first classic computer, I don't
have such a thing lying around either. :o(
I read something about hooking a serial terminal up to the machine
directly... Forgive me for dumb questions, but I'm assuming a serial
terminal is one of those boxes that I keep seeing that has hookups for
mice,
keyboards, SVGA monitors, and the like? Also called a 'Terminal Station'
I
believe... Will this work? I don't even know if I'm asking the right
question here, and I could be horribly, stupidly, wrong. :o) This thing
comes from 'way back in the day' for me, before I was even interested in
computers, so I don't know a whole heck of a lot right now. More
research I
guess...
Thanks again.

Fortunately, I've got the key. Unfortunately, I'm a newbie to ALL of

I doubt it has. It was just sitting there, and it doesn't appear that
anyone
has opened it in a LONG LONG time. As for AIX, I'll figure that out when
I
can actually use the system. I also read something very brief that this

that's
true?

Well, I asked this, just in case there was a problem somewhere.
Every other mailing list I'm on does not have a delay this bad. I'm not
worried about a delay, but with it being 1.5 hours, it seems like there's a
problem somewhere. We're using Exchange here at work, so that might be it.
If anyone has any hints of stuff for me to check out here at this

I don't know what key is on the AS400, if it is a round key, just call a
locksmith, if it is a regular straight key, it may be like the ones on
the PS/2's I have, which are single tumblers, and can be picked with a
paperclip in about 10 seconds (take a small paper clip, straighten it,
and then bend into a U... insert points first into the lock, and jiggle
while turning it, you should be able to hit the right spot in a few
soconds). The more tumblers, the harder it is to pick, but generally,
anything 3 and under can be done with a paper clip, over that, you might
want to call a locksmith or get a lock pick kit.

Hi,
I have a contact who needs to get rid of a VAX 11/750 and an
11/730 real soon and they are in Sommerset County, New Jersey.
A picker-upper would be preferred. There is also an HP 3000/48.
Let me know who wants them and can pick up. If there is contention,
I think one should try sharing, so let me know which one you
really really badly want if you have to choose.
Thanks,

I got a great bunch of artifacts recently from an ex-Digit (DEC Employee)
who was finally not going to use his VAX for anything else any more.
These included:
A set a PAKs that rivals the Hobbyist offering
and exceeds it in that it has a PL/I and APL PAK.
Several RRD40 caddys and a couple of the SCSI version
of the RRD40 (I'm on the look out for the non-SCSI
version, will trade one for one!)
A VAXServer 3100/M48 (yet another one I didn't have
yet.) with all the option cards (multi-serial, DMF32,
etc)
A bunch of manuals, including the VT103 users guide
and a bunch of VAX 11/730 manuals (including the CPU
technical manual!)
An Ultrix-32 Condist for VAX (v3.0)
Three VMS Condists (5.2, 6.0, and 6.1)
Cables for various things.
Some RTL replacement parts for the PDP-5 !!!!
Bits of ephemera from the DEC hey day (VAX brochures,
DECUS disks, etc)
Some more docs
Available for trade:
TU58 Technical Manual
TU58 User's Guide
RL02 User's Guide
RL01/RL02 manual
Some DECConnect stuff and a crimping tool with about
20 MMJ "heads"
Lots of little detail parts that are so hard to come by when you need them.

That used to be two separate magazines, "Practical Electronics" which was

In search of 6 of the vented original 5.25" half height filler plates for my
new Server 320 - just mainly for looks. I have all the bays full of hard

hot swap trays fit the 320 so maybe the 325 filler plates work as well.
Will pay up to $1 each for them (plus mailing of course) and would love it
if one person has all of t hem but can get one or two from each person until
I get what I need. OR I have some excess SCSI controllers and memory cards
(no ram) for microchannel 286 and 386 level machines I can trade if
possible, as well as various ESDI hard drives from PS/2 55SX and 70

I'm gradually getting my collection esconced in my new home in the boonies
of central Manitoba.
In trying to set up my beloved Next Color slab I'm dismayed that the 17"
Megapixel isn't functioning. Before, the monitor was a bit flakey and would go
to sleep on me occasionally. I've tried to find specs but the only useful one
I've found is in the Peanuts FAQ archive. Unfortunately it gives no
descriptions of the external controls.
On the lower left side of the display is a button with a screen and vertical
line symbol which doesn't appear to be working. What is it's function ? I
had imagined it was a screen blanker. Also since I get static discharge on
the screen when I depress the on-off in either position what is the ON
position of the switch. In to the cabinet or protruding from the face. I've
forgotten. I've been avoiding opening up since there's so many other pressing
things to be done and you can't see thru the air-vents to see any life.
Thanks for any help.

Hello Everyone,
I've got some DEC SBB (Storage Works disk cartridges) boxes that the
previous owner "liberated" the SCSI drives from. I thought I might put some
drives that I have in them however they are clearly set up so that one
"backplane" was used for each particular drive. So to use these I'd need to
replace their innards with 4.3GB drives.
I would like to know which 4.3 gb SE SCSI drive DEC/Compaq/HP :-) used in
these so that when I find one or two I can replace them. Conversely, if
someone needs/wants an empty SBB box let me know.

Mine is the later LB+ that has the SCSI chip {5380} on board. My box is
one I got at DEC that is exactly the same size as a BA11-VA with same
openings but from a proto so it's light grey {DEC 68} and aluminum and
compact.
It has:
Fujitsu 45mb 3.5" SCSI
Two 3.5" floppies (720/781kb)
I use it with VT240 or 330.

Yes, I know of at least three bidders that are businesses. I also know
that they can always outbid me, and at least two of them use some kind
of automated sniping tool.

Hi Gang,
With our contacts to 1200 companies, in 100 countries,
on 6 continents, my company is going to try to source these
parts. It's doubtful they would buy directly from private
individuals in single quantities, but we will. If any of
you have CPU and Memory modules for VAX 7800's that you
would like to sell, email back the module numbers and your
asking prices immediately.
Sincerely,
Bennett

My AmproLB doesn't have the SCSI daughterboard so I prefer an emulator.
I used to have the LB stuck in a full-size tower with my Wintel system
along with a couple of 5.25" floppies. The primary serial port went
back to one of the Wintel system's serial ports and the light and reset
button went on another 5.25" cover plate. Unfortunately an emulator
was more convenient.

Ok,
We all need a topic to take our minds of the WTC attack. Here's
one I've been meaning to bring up, surely it will generate a lot
of discussion.
In a recent thread, Tony Duell expressed a lack of interest in the
emulators and simulators of old iron that are now circulating. His
reasons centered around his love of hardware. From my perspective,
it appears that for Tony, the experience of computing cannot be
separated from the experiencing of the computer.
My reading of this mailinglist's charter leads me to conclude that
the group is here for the benefit of the Tonys (BTW, Tony, I'm *not*
picking on you) in the world, those for whom the hardware *is* the
end-all be-all of the Classic _Computer_ experience.
I confess I don't like that- the Classic Computers for which I
lust the most will forever remain inaccessible (and few examples
will even continue to exist). However, as both an RJE operator and
as a mainframe user, I found the experience to be more about the
_computing_ and less about the _computer_.
Exceptions included (back in the 70s) of building an IMSAI, a SOL,
hacking a KIM-1, etc. But after we got the hardware running, the
fun part was in creating the _computing environment_.
So, I think the formal name and the charter of this group should
change to reflect an interest in Class Computing. The only real
change would be that discussions about the eumlators and simulators
would no longer be OT unless they drift into details of programming
the emu/simulators themselves. Additionally, more detailed discussions
of the Classic Operating Systems would be similarly on-topic.
I'm not sure how many of you have ever thought about this; but
now that I've broached the subject, whaddy'all think?

I've also done some embedded systems hardware development. But it
tended to be taking the evaluation design from the databooks and
massaging it into a working design, so I can't take too much credit.

BTW, if it wasn't implicit (it is to me), I wouldn't have much of a need
for an emulator for a machine that's readily available, or if rare, easy
on the pocketbook to keep running (parts, electricity, etc).
We can't all be Megan Gentry, Eric Smith, or Daniel Seagraves (owners
of DEC-10&20s who come immediately to mind)...
Now, Jim Battle's doing a SOL emulator. Great idea, I might want to
play with a SOL at work. But my SOL was the machine I did exactly the
kinds of things you describe. Unlike many, I didn't buy even the complete
SOL kit. I bought only the motherboard and a folder of schematics and
instructions for component assembly. By December 1976, all it could do
was display a test pattern consisting of essentially a dump of the
character generator ROM. As time went by, I continued buying components.
It was getting close to being finished, but I needed a keyboard. I bought
one surplus, taken from a TI Silent 700. However, the strobe was inverted
and either too long or too short (can't recall). So I fingered through
Don Lancaster's TTL Cookbook until I came across the 74121, which I hadn't
used yet. I used it to change the strobe width, and one gate in a NAND
wired as an inverter to flip the logic direction.
Next, I needed some kind of key-repeat. Like many early terminals,
there was no auto-repeat, but instead, the keyboard included a
REPEAT key. A couple of 555s and some more gates from the NAND,
and I was almost done. I ended up adding a lightpen interface to
the design, then built it up permanently using a Rat Shack proto
board. Stuck that inside a generic keyboard enclosure along with
the TI keyboard, and I could now talk to my SOL.
For a monitor, I followed Lancaster's instructions on how to take
an old B&W TV set and pull the unneeded circuitry (except for the
tubes; they stayed in, heaters wired in series). The mods all helped
boost the bandwidth of the monitor a bit. The image quality ended
up being quite good, and I sold it to another guy who'd bought a
complete SOL kit sans monitor (I'd bought an actual monitor by
this time).
I enjoyed every minute of the 18 months it took me to make that
forty-dollar naked PC board into a usable computer. Or termninal,
actually... its raison d'etre was to hook up to my beloved and
much missed CDC 6600 & DEC-10!
And I think I even got to like the smell of solder.. especially
the Ersin Multicore stuff made in the U.K... why, there's some
now, and no iron in sight...
But as much as I enjoyed fooling with hardware, the software had
an even stronger draw. Just as you can only erase a piece of
paper so many times before it disintegrates, you can only re-
solder a PC board so many times before you've fried it. And
yes, I've used all kinds of techniques to repair such damage.
But you can't damage software... which is one of the things that
I find attractive about it. Emulators represent the ultimate
convergence of hardware and software...
Hey, I just had an idea... how about an emulator that goes all
the way down to the component level? One which actually emulates
resisters, capacitors, transistors, and 7400-series chips. It
could also have an emulated soldering iron & solder. Ever wish
you had three hands for a difficult assembly? No problem in this
proposed emulator! We'll just add an emulated hand... or two... or...
;-)

I just realized that every now and then I still use the first
editor that I learned for the ibm pc, whenever I'm too
lazy or don't need the power of vi (and the file that I want to
edit is less than 64K in size). It is called see.exe
and it is 32768 bytes long. The version string reads
SEE: Screen Editor V2.0: (c) 1982,83,84 Michael Ouye
The file date is 3-16-84.
For its size, it is actually pretty useful and you
can even record and replay macros. It is one of
the first programs that I copy to any pc-compatible
even if it (the pc) has been winblowsized. Is anybody acquainted
with this program?

inspect though.
Look at the AlphaServer 2100 memory auction too: same price!

I sincerely agree as to the tragedy of recent US events. My heart goes out to all affected.
HOWEVER, this is a classic computer mailing list. The discussion on the WTC stuff is very interesting, but it belongs on all the myraid of other lists present on the net for this purpose.
What on EARTH posessed people to think we needed blow by blow updates on this list about current world events? Think - if you have to put "OT" in the subject of your message, it probably doesn't belong here.

Hi, see this
http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=1274886271
he's trying to sell a VAX 4000 CPU for $999.0 and no, it's not a
typo, BuyItNow says $2000 something.
cheers,

This is one monitor I can no longer justify owning. It is a nice trinitron
VGA monitor with few hours on it, however it is a fixed frequency
31.25Khz/60Hz monitor. It makes an excellent "spare" monitor for a laptop
with a damaged screen or a rack mounted system, etc, etc. At 13" it doesn't
take up too much space and its easily lifted by one person.
Its in Sunnyvale, CA. If you're willing to pay the packing and shipping (I
do not have the original packing material so I would have to take it to be
packed) I can mail it to you.
Fortunately, it looks like tomorrow I'm going to finally get my mailings
done for those of you who are patiently waiting.

Perchance does anyone have an operations and/or maintenance manual
for the Qualstar Model 1260 9-track tape drive? This was a popular
drive in the late '80s and early '90s, especially for use with PCs.
It's very compact, works in vertical or horizontal attitude, and
is basically reel-to-reel without any tensioning mechanism. It was
sold by Qualstar and in systems by other vendors such as Overland
Data and Chi Corporation.
Thanks.

No so unconventional... I started with hardware (hacking the family TV,

Again, I didn't want you to feel picked-upon. However, for each of us
who posts, I'd bet there are ten who don't. Of those of us who do post,
each of us appears to represent yet a different facet of this interest
area. You post a lot, and I believe, whether you realize it or not,
that you represent a viewpoint held by many subscribers. In siezing
upon your words, I was really trying to focus on one particular
viewpoint, in order to place it in comparison and contrast with a
different viewpoint.

It can quickly degenerate into "this version of GCC does <x> but
doesn't do <yz>"... most of the sims are relying on GCC for portability.
Or, do we build it as one huge monolithic source, or modularize the
source? Separate execution modules running as native processes, or
one big carefully-coded "superloop" that polls everything?
For that level of discussion, it may prove beneficial to have
a mailinglist dedicated to emulator/simulator theory. But if
there is insufficient interest to mandate a separate list, ok,
this is as fine a place as any for the discussions.

Agreed... -dq
