I have personally worked with scientists from the University of Wyoming and
technicians from NASA Goddard Space Flight Center who directly and indirectly
measure the ozone hole and the chemicals that are harmful to ozone (CFCs,
Bromine compounds, etc.) I have helped launch balloons and collect telemetry
data. No doubt that I'm not an unbiased source, but even though I think CFCs
are nifty compounds at ground level for lots of tasks (cooling, cleaning,
etc.),
at 30,000m, they are not a) natural and b) harmless.
At McMurdo, in spaces with electrical equipment, rather than Halon, there are
built-in C02 fire-supression systems. They are much larger physically, and
harmful to humans, but CO2 poisoning vs. Halon suffocation leave you just as
dead.

I've been given an assignment to research and compare the differences in the
IBM 350, 1301 and 3350 disk drives. I've been searching most of the moring
and haven't come up with very much at all. I've checked the IBM site and find
mostly current hardware. I've
search several other sites and find only brief references to the devices.
Would you happen to have any leads that would help me find the Platter
diameter, rotation speed, capacity in MB and data tranfer rates of these
devices. I'm not asking for answeres, only for possible leads to the
information.
Thank you for your help,

A couple years ago we had a thread about Halon fire-suppressing systems
used in computer rooms. Through the school of hard knocks,
I just learned first hand how such systems operate.
Today at work (let's just call it a "large employer in the Washington
DC area") we had a memorable incident in Operations Control when
someone (with undoubtedly good intentions) unscrewed the
solenoid controlling the valve and dumped - without warning -
2500 pounds of Halon 1301 into the room in just a few
seconds. (Operations is a *big* room. It was fitted with eight
giant red tanks of Halon.)
Normally there'd be a thirty-second delay as an audible alarm
allowed the occupants to clear the room, but this feature is
bypassed if you go straight to the solenoid!
The sudden pressure from the halon dump sent numerous ceiling
tiles flying, as well as large stacks of paper that were blown off the
consoles. Not everyone evacuated immediately - several folks
in safety-critical roles stuck around for ten or fifteen minutes
until the firefighters showed up with air packs that allowed others
to relieve them. Some who did stick around eventually left
in ambulances (I *hope* just to run some precautionary tests.)
The good news: the computers didn't hiccup at all during all this.
Moderately good news: Halon dumps aren't instantly fatal.
Seeing as how I spend a good fraction of my day within a couple
of feet of some giant red Halon tanks in the concrete bunker -
oops, officially it's called "computer room" - this is good to know.
I'd been heavily trained that when the Halon dump alarm sounds, you
*get out*. Now I know a little more, especially about the dead-man
switch you can use to delay an electronically-triggered dump.
This Halon is Good Stuff. Other than some grit blasted from the
ceiling tiles, there was zero debris left in the machinery.
What's the "environmentally friendly" equivalent used today?
Is there such an equivalent - something that will put out a fire,
but at the same time not damage vital equipment?

Looking for a six in a pile of nines...
VCF 4.0 is September 30-October 1
San Jose Convention Center, San Jose, California
See http://www.vintage.org for details!
Well, my current job will be over next December and
I will have to move elsewhere. Unfortunately, I won't
be able to take all of my stuff with me, so I have to
get rid of things. I'll offer a few things on the list
first, then try to sell it on eBay. Other things go
straight to eBay as I don't think that there is any
interest for them here. So, here's a summary
(and before I forget, location is Ithaca, New York;
some stuff is at home and other stuff is at the
Electrical and Computer Engineering School at Cornell).
Only partial description are included; if you want to
know more particulars about something please send me personal
email to cem14(a)cornell.edu . So here's the list:
- (1) microvax II in BA123 case, 14MB RAM, KA 630-A.V1.3,
M7555, M7546, RQDX3 (apparently wiped). I had planned
to play with this system, but never found a SCSI
interface, I have no tape drive for it, and I could not
figure out rapidly enough how to load the OS from the
network (it does have a DELQA card). The case is missing
one of the side covers (but the card cage is intact).
The rubber ring on the wheels of the case is disintegrating.
Goes through self test; when you type "boot dua0"
it answers "?42 NO SUCH FILE, DUA0".
I also have a maxtor XT4380 and a card that is a licensed
copy of the Webster WQESD which might be handy for this
system. I really want this system to go to a good home.
- (1) vaxstation 2000 with 6MB RAM (I believe). I'm keeping another.
- (1) Decstation 5000/125
- (1) Decstation 5000/133
Note: these decstations come with one HD bracket each, one of them
has a 425MB HD with netBSD 1.4.1 . I think they both have 16MB RAM,
but I'm not sure. I can install netBSD 1.4.2 if you want.
- (2) Decstation 5000/33 (maxine) with 400MB HD's, 16MB RAM,
one of the nicer framebuffers and corresponding monitor,
keyboard and mouse. Currently with Ultrix 4.2, I think.
Or was it 4.4? Anyway, since Ultrix is not transferable,
the buyer should erase the hard drives. NetBSD runs in
them, but the nice framebuffer is not supported (yet).
- (1) Decstation 2100. This machine worked non-stop as an
ftp server for nearly five years.
- (4) Storage Expansion Units for above; two have the same box
as the Decstation 2100, another one is in the same style of a
Vaxstation 4000/60 (which I also have, but I'm keeping :-) .
The last one is in the same style as the box for a Vaxstation 2000.
- Lots of ULTRIX documentation for above.
- (2) Sun IPC's with working NVRAM, and (2) more for parts.
- (3) Sparcstation 1's and 2's, some working, some non working,
one or two systems should come out of all the parts...
- Lots of SunOS 4.1.3/4 docs
- Many HP9000/300 systems, including a 433s with 33MHz 68040,
370, 350, 340 and 320 systems, as well as HPIB hard drives,
tape drives, tapes, memory, storage expansio enclosures and
other stuff that goes with them. I'm keeping a 380
system with SCSI and a 25MHz 68040. Wish I could keep the 433,
but it is too big.
- (4) Racks for the HP9000/300 series. If you think that the
BA123 case is nice, you should see these...
- (3) HP9000/720's in working condition. I can install
HPUX 10.20 for verification purposes if anyone is interested.
- HP9000/236 system with monitor and storage expansion box.
The only system that actually has an "any" key in the keyboard :-) .
No software or OS, though.
- HP 1000 E-series. It breaks my heart to part with this; it is
the oldest system I have and I really wanted to bring it back
to life. Believed to be working, but I don't have enough
expertise to test it. (Frank: I have the list of ROMS somewhere;
I'll post it later). Some cables for the serial cards are
included. An HPIB HD came with this machine, but it seems to
require service.
- Exabyte 8200 with enclosure.
... more things to come.
Most things are available for a small price; others, for the
cost of shipping + 20%, since I'm interested in finding a good
home for them. Would anybody like to pick up the microvax II?
Regards,

I have an opportunity to get up to a dozen DEC Computer Lab units. The DEC
Computer Lab was a tabletop digital logic trainer (see attached picture)
providing gates, flip-flops, a clock source, switch (full throw and pulsed)
inputs and lamp outputs that allowed a student to wire up various logic
circuits using patch cords.
These units are mostly complete (some may be missing rocker switch covers or
have some burned-out lamps) but do not have patch cords or documentation and
are as-is. I may be able to provide a Xerox copy of a DEC computer lab
workbook for copy costs if desired. We're looking at about $200-250 per
unit, plus shipping/copy costs as required.
I pulled the attached picture off the web to show an example of how the lab
looks, I don't have a picture of the specific units that are available.
If people are interested, I can collect some bucks, pick up the units, pack
them up and ship 'em out. Please contact me off list and let me know if
you'd like one of these lab units.

Hmm, well ignoring the heat, green house gasses, etc... I see it this way:
each pentium sold = more $$$ for intel, which lets them buy more companies
(they apparently own the justice department already, since they're more of a
monopoly than microsoft), each new company = more money = more crap by intel
= soon leads to the point where I give them money every day = quickly
removes my desire to live. Of course, with as crappy and buggy as their
chipsets, etc. have been getting, it might be debateble whether they'll
achieve total world domination or explode in their own craptacular way...
This is totally opinion,

Back in my Prime days, when we got our Halon system, the salesman
demonstrated it at their cost after installation. Triggering it
deliberately, the result was as you describe. Additionally, boxes
of greenbar that were open had the top layes of paper sucked out
of the box, without breaking the perfs, sending it flying.
He stood in there for 15 minutes, lighting matches which went
out immediately, so we could see how well it worked. He drove
away in his car, didn't crash or die. As it was explained to
me, Halon is safe, but under temperatures that would kill anything
organic, it can transform to a deadly gas.
The joke was that the gas didn't kill you, but the reason you
weren't supposed to be in the room if you had to trigger it
manually was to avoid the shrapnel when the spheres exploded.

Again, we were told, given the choice of breathing air or Halon,
choose air everytime. But Halon was safe and we didn't need to worry.

You can buy small Halon extinguishers still, but only at your local
civil airport for your plane. I have recently heard, however, that
there is a replacment gas that does just as well, but can't recall
its name. Does seem that it starts with an "H", though.

I know that earlier Vaxen used PDP11s. A quick search
of the net yielded little information about this model.
I've got a line on one about to be dismantled and want
to find out if theres anything in it worth salvaging. Don't
have access to it, its 1000 miles away. But I have a friend

This is soooo far off topic...
CFCs are distributed somewhat uniformly over the stratosphere. The reason
why Antarctica is the location of the hole is due to climate... You need
several things in proximity to "cause" the hole - A halogen ion (Chlorine
and to a lesser concentration, Bromine), a place to work and energy. The
place to work is the surface of certain sizes of ice crystals (high-altitude
clouds) that only form at temps well below -60F. Sunlight is the source
of energy.
The ozone hole opens up in Antarctica every "spring" because that's when the
sun rises (providing energy) and that's when the air is cold enough to make
the proper kinds of clouds. By late October, it's warm enough that the
clouds no longer form and the Polar Convergence dissapates, allowing the
ozone-poor air over the continent to mix with "normal" air from higher
latitudes, diluting the ozone over Australia and New Zealand, primarily.
The way the model works, it's "natural" for the hole to open and close on
an annual cycle. The real question is, how much of this is due to man-made
sources of chlorine. The direct measurements show that CFCs released at
ground level take several (18?) months to make their way to 30,000m. Since
eventually the chlorine ion forms a stable compound, each one has a vast, but
finite capacity to convert O3 to O2. The hypothesis is that more man-made
chlorine in the stratosphere means less ozone. The data I have seen suggests
that the more we pump out, the more rapidly the depletion occurs each Spring.
For the skeptical: the above is not gospel written in stone. It is my
understanding of the best explanation of the observed phenomena to date.
I am not a scientist, but I did assist researchers in data collecting
and reporting.
We now return you to your regularly scheduled topics.

The good old british postal service 'happened' to the other CRT. They
dropped it when it was being transported and snapped the wee glass guide off
the back, as well as doing some internal scraping damage with the HD carrier
since it wasn't fastened in properly; I had a spare case, drive and CRT so a

The air handlers also helped in removing the halon from the room. As
I understand it, during a "normal" (electronically-triggered) Halon dump,
the air handlers would have been cut off to maximize the effectiveness
of the Halon.
In fact, I've heard that Halon's density makes it more dangerous than
if it didn't stratify. Unconscious folks, unfortunately, tend to have
their noses only an inch or two from the floor...

These guys (and gals) take their jobs *very* seriously. They aren't going
to let anything like the lack of oxygen get in their way!

Probably because in many systems like Eudora, "reply to all" replies to all
the addresses in the "To:" line and the sender. The "Reply-to:" takes
precedence over the "From:" and is set to "classiccmp(a)classiccmp.org", and
the "To:" was also set to "classiccmp(a)classiccmp.org", it gets sent twice,
and Eudora is too dumb to scan for duplicates.

I was in a computer room (aka "concrete bunker") about 50 feet under

just been in Operations about five minutes earlier...
When the halon dumped, the building fire alarm was set off (I think

>Moderately good news: Halon dumps aren't instantly fatal.
It can very nearly be.
It's an oxygen displacer and non combustable in itself and non
posionous but it's not oxygen! It can be lethal due to oxygen
deprevation. What makes it fairly safe like you saw is that
it's quite heavy compared to air and hungs the floor. Those
that didn't leave were in my estimation quite foolish.
Many years ago one of the halon similars (freon12) was spilled
in a room I was working in, roughly 35 gallons of it due to a
valve left open. I was quite blue when I was dragged out of
the room as it had displaced all the air and only the fact
that I'd been under the HEPA curtain doing work (also why
I didn't initially notice it) there was outside make up fresh
air added or I'd have been hospital fodder or worse.
Freon and halon are related as florinated or halogenated
hydrocarbons and both are low boiling point, heavy compared
to air and non combustable. They are also both oxygen
displacents makeing them dangerous in closed rooms
and effective for fire control (both as a mild cooant and
removing oxygen) while fairly inert.
I'm sure there are varients of R134A in use or similar
still used.

Hi Sean;
These Decstations have a window in the back through which you
can see eight small LEDs that display diagnostic info when
the system goes through POST. Is there any activity in the LEDs
on power up? If so, what is the last pattern that you see
in the LEDs?
Note that in many Decstations of this kind, the cpu runs too
hot due to inadequate cooling and they die. I've had this
happen twice.

NetBsd is a good choice for these systems. I have two. I also have
a couple of 5000/33's, but netBSD doesn't support the advanced framebuffers
that they have; it only supports the built-in framebuffer, which won't
talk to the monitors that came with the machines. So they're still
running Ultrix (ugh).

Just wondering if anyone knows if this could be a possible problem with this type of machine.
I have two DECstation 5000/200 systems. When I got them, one powered on but did not do
anything (no output on serial console on port 3), while one would work fine (console output
on port 3, seemed to be functional, etc). I did not have any external SCSI storage for them
at the time, so I decided to store them until I could make use of them.
About a week ago, I finally got a SCSI drive enclosure to mount a disk in, so I decided to try
getting one of the systems up and running with NetBSD/pmax. To my surprise, however, now
both of them do nothing on power-on! I had not touched them since I had power-on tested them
a few months previous, so I was at a loss as to knowing what had happened.
The only thing that I found that I even remotely suspect could be at fault is what looked like one
of those Dallas battery-backed clock/NVRAM chips. I was wondering if perhaps the battery had
died and this was preventing the system from coming up.
I was hoping someone else might have run into a similar problem and might have a few pearls of
wisdom to share.

Hi guys & gals,
Passed on the responses from the group here to the
guy in Qld regarding the GA 3345. It jolted his interest level,
and it appears it may have a safe home already.
Got the following response.
Quote:-
"I just rang the guy from yesterdays generally distributed e-mail and he
says
that the unit has absolutely no documentation, nor any sign what
operating
system it ran, and he is only guessing by saying it is over 25 years

has been approached already by the "museum" run by the UQ Computing
department and they have indicated they will take the complete thing off
them. (This museum is just a collection of PDP and other early stuff in
the
foyer of one level of their building).
Currently it is in the Qld Dept of Natural Resources Offices, Brisbane,
and
was being held by someone starting a surveying museum, but they realised
this had nothing specifically to do with surveying.
He has said he will contact me if the UQ offer falls through."
End Quote.
Just to make sure it won't become razor blades, I've made a firm offer
to take it if the

You put in another MVII board (or even a MVII and matching ram) and keep
trucking. Anyone whos wored with vaxen would know this.
The system HWID is not a serial number that I'm aware of but a
model/product ID so that VMS (or Ultrix) "knows" a bit about the
processor
(or chipset) and it's busses.

Ignoring the license issues if the media for both were say a scsi disk it
would run on any scsi equipped vax. My MVII has CMD SCSI, I build a
5.4 copy and backup/image it to a second drive which is removed and
placed in a MV3100... runs fine. Same for V7.2.
VMS if memory serves is not licensed to the specific CPU but to
the total users and per CPU used. So if you have a MVII and
upgrade it to a MVIII the license is still valid and all. Now if you
take the old MVII boards and build another system you will be
technically required to obtain another license. Most VMS based
layered apps were the same way.
This was a pet peve of customers as the MVIIs were cheap and the
bigger machines werent but the license was not based on if it were
a MVII or VAX9000 but by the number of users it could serve and if it
was a cluster member or cluster host. At the time (likely still) it was
a $3000 license and for some users that was chicken feed and others
that was the whole farm.
At times(through the '80s) DEC didn't realize how valuable their
software was and often acted like selling hardware was all of it and
software was one of those annoying things you did to sell hardware.
By the '90s hardware and software were often bundled and used to
drive sales of each other.

Wrong. The standard devices were usually AY-3-1015/COM2502
based and tended to use the MITS status bits and IO addresses.
Mits never used the 8251, and the 8250 was later to the scene.
MITS set a standard in as much as there were very few then
by sticking to the 2sio standard or the SIOB standard for serial
ports with the SIOB being a uart like ay-3-1015 and the 2sio
using 6850s.
Expereince says, the common usart like the 1015/com2502
was most widely use with the 8251(9551/2651) the 6850 running
follow on. The only S100 board I've seen the 8250 on was the CCS.
The 8250 was not a widely used part in the late 70s on S100.
I'd be quick to point out that the mits era was 1975-1977ish with
other players already emerging as new leaders (NS* horizon
and friends) by late 1977 in the S100 space. From 77-80 that
would again undergo major changes going from the MITS/IMASI
front pannel style machines to the Northstar*, CCS, Compupro
turnkey style front pannel less and disk based systems.
It was also simple enough at the time to fix IO in most code as
it was trivial in construction and easy to find in binaries.

>The HWID I speak of is a Unique ID per individual CPU.
True. And it identifies the basic hardware and CPU.
>Think relicence.
Keep in mind the basic "kits" carry no license or other
machine locked stuff. The license is applied during or
after the install. Even then I've built and installed systems
on my MVII and then carried the media to the MV2000
as both bootable and complete (even licensed if that
is within the written license terms). That was how we
cloned VMS sustems at DEC as it was faster than
using TK50 tapes.
I've put the VMS 7.2kit (cdrom) on everythingt from
MVII and VS2000 through 3100m76 and would expect
it to load and run on most any other VAX as well.
The biggest problem of installing on older hardware
is the minimum system (ram and disk) has grown
during the years and early version coulld fit on 30mb
disk and 1mb ram that has grown to over 150mb
disk and 4mb ram. Though it is possible to shoehorn
the latest version is to less than the specified disk
and ram it is a exercise fort the experienced and will
produce a system of limited utility.
>So, Any old copy of VMS can be relicenced for a
>matching or nearly matching architecture machine?
Well since all VAX are by definition matching hardware
there is little issue. However there are exceptions
like the RTVAX which is not totally cpu compatable
VAX and differs in the translate tables, it never ran VMS.
>Tell me, is that through Montagar?
The VMS7.2 Hobbiest version is available there. Note
HOBBIEST version does not mean stripped or limited.
It means it's packaged with many hobbiest desireable
packages besides VMS itself.
>P.S. Can users fo VMSbuilds?
VMSbuild is a standard utility and is used often to configure
custom installs once you have a configureation you want
to standardize on. Anotehr useful VMS utility for small
systems is VMStailor which allows trimming off or adding in
libraries, fonts and other peices to tailor a system.

I am not familiar with this model. Many GAs used the PICK operating system.
I had a GA 5000 at one time and it was a Multibus machine with a 68000 CPU,
32 user ports, 150 Meg 14" Priam HD, 1/4" tape, 1/2" Cipher tape, all in a 5'
high case. Top of the line in it's day.
I may have some of the PICK manuals around if anyone is running one of these.
I recommend trying to save it.

Therein lies the problem, as back then the average MITS or IMSAI
did not have any rom and no concept of a BIOS, it would be CP/M
that originated that concept for small systems and called it that.
Even then the CPM bios only hid the underlying IO with standard
interface and the IO could litterally be anything on the map (often was).
If anything the idea of canned IO was something unique to systems
like the SOL and a few others and rare in the s100 world.

First a word from... When DEC says Support they mean assitance not
it will not work. Support is a service they provided and if it's
supported
you could under your support contract call and expect help. If it was
not supported it will likely run but don't call DEC support if it
doesn't.
So that means prior to MV2 is not "supported" but the drivers are
likely there and work.
I'd expect a 750 with RA81 and 8mb ram would run V7.2 just fine.
But if you ask around older 6.2 and V5.5 kits arent that hard to
find. Their owners will likely let you borrow them as it's up to you
to get your own license pak which is not tied to the media.
I have it on good word that V7.3 does still run on MVIIs.

I guess that my question was partially answered by Jim. Using Altair BASIC,
BASIC polled the switches (at port FF) in order to determine which ports to
use for various I/O. Disk BASIC was the choice (running over CP/M), the BIOS
would have to be recompiled with the proper port locations for the hardware
one was using.
What I was kind of getting at was as follows. If I wanted to provide
emulated console I/O, what port would I virtualize so that any software I
loaded would run? I guess that my PeeCee-centricity was showing a bit in
that in the PeeCee certain hardware ports were always at the same location.
So, the conclusion is that if I want to emulate a single console port, I
have to select which serial board to emulate (the 2-SIO for example) and
virtualize ports 20Q and 21Q.
It also sounds like that I need to trap input port 0xff as the "sense
switch" port. This may be done in the emulator already; I have to check.

Hi
There was no standard port used for serial I/O. and even if
there was, the device could have been a AY-3-1015, a 8251 or
a 8250. All of these would have different handshake and
setup information. I don't know how you'd be able to have

I've used it since the early '80's but my work has hovered over the low-end
capabilities of the language. Now that it's obsolete, I'm trying to make up
for all the stuff I didn't learn when it was mainstream. I've had people
tell me about features I've never even read about, and there are plenty of
them that I haven't used and HAVE read about. It's pretty simple if not
compact, to do everything with logic equations, and that's what I've always
done. Now I'm trying to catch up on the built-in state-machine dialects.
They use several constructs which have carried forward, somewhat, into
Verilog and VHDL, but not in the same way or with the same syntax as PALASM.

It occured to me that the quite modern and today mainstream language Abel
has somewhat similar constructs, and is part of most modern electronic CAD
systems. While having retained quite some similarity with PALASM, it may be
closer to today's tools like VHDL.

As Zane mentioned, he's getting a used Metcal SP-200 station to
play with. I also know this because he got it from me.....
For those of you who don't know, these are professional-grade
induction-heating systems with extremely light handpieces and
dozens of interchangeable tips. Heat is practically instantaneous,
and they are also static-free. They also run about $400 new.
The surplus shop where I work during a goodly portion of my free
time has a limited number of power supplies and handpieces
available, unfortunately, no tips or stands. We got them from an
electronics plant that shut down. Tips range from about $15 up to
$30 new, I think, depending on the tip.
If you're interested in one, email me off-list and I'll let you know
what we have. These are great irons -- I have two (one at home and
one at work) and absolutely love both of 'em. I hung up my Weller
and my Ungar when I got the Metcal.
Thanks.

Hello, all:
Just a quick update on my progress with enhancing the Altair
Emulator. I also have an activity log on my Web site which all can view.
Most of what will go on over the next few weeks is code testing as a
complete recompiled "altair.exe".
A few notes:
- The emulated paper tape punch code works on a standalone basis and
has been integrated into the overall emulator. This is the code I need to
bang on.
- I wrote a bus I/O emulation Windows DLL to handle actual I/O
through the PeeCee's parallel port. I still have to build a little test jig
to connect to the port (an inverter, a latch, and a bus transceiver). This
gives the emulator 8-bits of external address space and 8-bits of I/O with
*ALE (latch control) and *R/*W signals. The way this is setup, the parallel
port is still shared with other Win32 processes. If this doesn't work for
the emulator, I'll have to write a dynamic virtual device driver to gain
exclusive access to the port so long as the Altair is "on."
- In a few weeks, I'm going to tinker with console emulation either
through capturing a physical communications port that has no underlying
hardware (like COM5:) so that a Windows terminal program can "connect" to
the Altair Emulator. Alternately, I may try just building a virtual-VDT into
the emulator.
- Other enhancements will hopefully include a virtual floppy drive
and the ability to "install" ROM.
One I have the base code stable (it now compiles/links with no
errors), I plan to make the binary available for testing and the source
available for review. Some of the punch code could benefit from
optimization, no doubt.
I also have some questions of actual users of the Altair. I wanted
to use a copy of Palo Alto Tiny BASIC on the emulator (because that's the
BASIC that I have), but TB relies on CP/M for console I/O. Regarding the
original Altair BASIC, did the BASIC code provide its own I/O services or
did it use CP/M also? What port locations were generally used to service
serial ports used for console I/O? Does anyone have a working set of CP/M
binaries that I can load into the emulator?
Again, any help is greatly appreciated.

I can think of reasons why not. namely enough ram and
enough disk as the minima is 4mb ram and 300mb disk
though you can get by with less. Most 750s have enough
of both. With 8mbram it runs fair with 12 it will run good.

Or the MITS SIOA and SIOB at 0/1 with one of two possible status bit

Do you plan to emulate the BIOS IO to the ports and disk system?

re-hwid??? whats that. All I do is use a machine that I can
do a VMSbuild on to my spec, no biggie.
The biggest issue with recent copies of VMS is device
support for acient devices. The key here is SUPPORTED
as een unsuppported acient device drivers are often included.

Yep, and yep.

Why? old copies of VMS are still around and they are not
locked nor are new ones. You only need a license pak.
DECs use of HWID was to make sure there was hw/sw support
for things like what ()-float types the machine supported and
what instructions needed trap emulation. Newer versions lise
all older machines and the only case where thish could be a
problem is if you were trying to run V3.6 on a VAX10000
not the reverse such as 7.2 on a 11/750.
Allison
Thanks to all for giving the information on the needed power
supply and batteries for the HP 110 Portable Plus (it is
indeed the Plus). In particular, thank you for correcting
the power output of the 82059D as being 8v AC under load.
(My source for it being 6 V was from Mike Simms FAQ on the
HP1xx series of personal computers -- he has it in there
as 6 volts -- so someone may want to have that changed.)

My initial contact with CVSI regarding a special licensing procedure for
preservationist has seemingly not been taken seriously by the licensing
department. At this point, they continue to view licensing of Primos et. al.
as a revenue stream.
This is most strange since it has been determined that CVSI does not own
any intellectual property rights for anything Pr1me related. Those rights
remained with Computervision, and are now property of Parametric
Technologies
Corporation (PTC), who is probably unaware of what they own.
So preserving Pr1mes at this point in time remains a black hat activity.
:-(

Cool!
But what was the original post under this subject? Something about

Having current and semi-current manuals kicking around
isn't really the issue though. I've seen more PDP-8,
PDP-10 and PDP-11 era manuals outside of COMPAQ/Digital/DEC
than I ever saw inside.
For VAX, PC and Alpha material the situation was
much better inside.
I wonder how many VAX hardware manuals will still be available
internally to COMPAQ in maybe ten (or five) years time?

I'd like to play with the NeWS system, since I've never seen it and
am intrigued...
Has anybody got anything at all related to this? Old Suns, old copies
of SunOS which included it, docs, example programs, ... ? I'd like to
buy a working setup.
My main interest is that I'd like to build a similar system for cross-
platform GUIs.

OK, since I now have two pieces of equipment I need to get a decent
soldering iron to work on, I'm wondering if people could make any
recommendations. I'm needing it for my PDP-8/m front panel, and for the DEC
VR260 I want to revive. I'll probably pick it up from Fry's this weekend.
I'm thinking I want a WES50 Weller Soldering Station, as it looks like a
good balance between cheapness and high-end. Of course anything would be a
good replacement for the el'cheapo 20 year old Radio Shack Soldering Iron
I've currently got :^) I've got to admit that the WSD80 looks nice though.
Oh, in researching this I ran across this web page that might be of interest
to people, "Basic Soldering FAQ"
http://www.epemag.wimborne.co.uk/solderfaq.htm

I just picked up an Olivetti L1 Computer at Goodwill. The CPU, keyboard, and disk drives are in one unit, kind of like an Apple III. The monitor is seperate, and gets its power from the main unit. All the main keys have BASIC statement on them (PRINT, OPEN, INPUT, etc...). When it boots up, it says:
Bootstrap Loader Version 1.0
Insert Disk And Press Enter.
Does anyone know anything about it? I couldn't find any information on the internet. Does it have BASIC in ROM? If so, how do I get to it? If anyone has any disks or manuals, that would be great!
Thanks,
Owen

Hi,
I picked up a couple of Epson PX-4 handheld/laptop computers a few weeks ago.
Have not got around to testing them yet. Any identifying text which used to
be on the rear labels is no longer there.
There is space for a plug-in device/cartridge on the righthand side above the
keyboard. Both computers have what appears to be a 1 megabyte static RAM
cartridge (possibly battery-backed) in this space. These must have been quite
expensive when new. I opened up one of the cartridges. Text on one of the
PCBs inside mentioned (from memory) POCKET COMPUTERS LTD 1993, so these are
quite recent.
In the EPROM sockets underneath the computer is some kind of auditing program;
the label read
Pocket Computers Ltd
AUDITOR V5.2
The labels also mention CP/M 2.2.
A web search for "Pocket Computers" Auditor didn't turn up anything. Does
anyone have any information on this company?

I found a manual for the Link MC70 terminal. Apparently its 4014 compatible
so all I need to draw on it are some routines that know how to talk to a
4014 :-)

I've got a box full of old data books that are free for shipping. (which
will be a bit since they weigh about 24lbs) Included are
GE Transistor Manual (sixth edition 1964)
RCA Transistor Manual 1964
SCR manual
SCR Applications
Power Supplies
Motorola Zener/Rectifier Handbook
Optoelectronics catalogs
Siliconix applications
HVSR designers guide
LSI design catalog
and a few others
Either pick them up in Sunnyvale, or pay to ship them to your address.

After a lot of negotiation and long delays, I finally picked up a Zilog
Z-80 Developement System today. There are two large boxs in the system,
one has two 8" floppy drives and the other has the main electronics.
There's also a pod connected to the electronics box by a cable. Does anyone
have any manuals or other information about this system? The only thing
that I have is some Zilog brochures for it. BTW stickers on the disk drives
are dated late 1978. I'll try to post a better description and pictures
next week. This weekend will be taken up with the Melbourne hamfest (Yippie!)
Joe
I checked on my unit's. They're blue with a biege band about 2 1/2"
tall around the top. The name plates have a brushed aluminium finish. The
CPU box is a model "ZDS" and it's also marked "1/40- 32K CPU" and
"05-6013-01" and is serial number 26. The disk drive unit is marked
"05-6013-05" and "1/40- 60K" and is serial number 275. I found a 32
sectored hard sectored disk in one of the drives. It's marked "PTR V7" "DO
- T" "1-40" "5-12-82".

Yep these require hard sectored disks at 32spt.

This year's Radio Club of Tacoma (WA) swap was both a miracle and a
disappointment. It's rare that the two go together, I know, but it did in
fact happen that way this year. I claim "appropriate posting" to the list
for this because what I brought back is over ten years old, and can most
definitely be used to troubleshoot computer systems.
The miracle: Every so often, someone will show up with one or more pieces
of hardware or test gear that are incredibly useful, are either working
(but may be out of cal) or have only minor problems, are priced to move
rather than at "E-pay average," and where the seller has little knowledge
of just what it is they're moving.
Such was the case yesterday morning, and the fact that I had gotten seller
space this year, and was as a result able to walk around the place before
they let the general public in, is the key reason I think I scored the
following for all of $250.
Two Tektronix digital scope mainframes: An 11401 and its GHz-capable
counterpart, an 11402. Along with said mainframes came a total of four
11A32 plug-ins (two-channel vertical, 400 MHz official spec, but you know
Tek always rates conservative), an 11A72 (up to 1 GHz two-channel vertical,
50 ohm inputs), and a big operator's manual about 2.5 inches thick.
After I picked up my jaw off the floor, and wrote the guy a hasty check, I
found, in the operator's manual, a postage-paid reply card from Tektronix
that offered a free service manual for the whole works simply by filling it
out and feeding it to the nearest USPS drop box.
The 11401 mainframe had only one minor problem: It failed it's self-test
at the A/D converter section. Said problem was completely cured by the
simple expedient of disassembling the unit, vacuuming out the dust, and
reseating the few socketed chips on the analog board.
As for the '402, I'll try the same tactics on it 'cause I don't think
anyone's tried it as yet. It's fine for the first hour or so. After that,
if you power-cycle it, you get a failure in the timebase section for the 20
MHz clock. If you let it cool down a while, the failure goes away.
I wager 1,000 Quatloos that this is another case of 'press the chips back
down and vacuum.' Even if it's not, it still sounds like a minor part. As
for the plug-ins, two of the four 11A32's fail their self-test with gain
calibration errors for Channel 1. I'm not sure what's causing this, but I
hope it's minor.
My only other complaint: The '402 has some light screen burn. Fortunately,
the CRT is nothing really special: Just a mono-green tube made by
Mitsubishi. Bet I could even find a generic replacement.
And now, the disappointment(s): The event was supposed to go until 15:00
local, but by 13:15 or so, everyone but the commercial sellers had cleared
out. Also, the event itself was not well attended. I'd be surprised if we
broke 1,000 people the entire day.
As for variety of stuff, that worked out pretty well, but even here in the
NW I'm starting to see less of people that want to tinker, and more of
people that just want to 'plug-and-play.' I base this on the fact that I
saw a LOT of "interesting" items in terms of older test gear, but
practically none of it sold even though the prices seemed pretty reasonable
(to my eyes).
There was more than adequate seller space (three buildings worth), but the
buildings were separated by several hundred feet of distance, and required
considerable walking to cover. While the walking itself was not a problem,
I found it annoying that everything was not all in one place, as it is with
most other swaps.
Finally, I think the club's timing was bad. There was a major computer
swap meet (the AM Northwest people) held in Kent the same morning as the
RCT event. They even started at the same time. I'm sure this was a drain on
attendance because I've been to the AM-NW events, and they definitely run
all day and are often quite packed.
I'll be forwarding feedback to RCT on the above, along with suggestions
for better timing and some other minor improvements.
'Til next time...

??? MITS had nothing to do with DEC or RSTS11 OS. So my guess is they
were user submissions of some basic programs not the MITS basic
(billy gates would have fits over that one too). Also MITS never did
anything
with 8008 that I ever heard of.

Well the .bas suggest they could be basic but are they tokenized or

Right now I don't have a paper tape reader (Doug Quebbeman has mine, and I

Tony is absolutely correct (as usual). I plead stupidity: I should
have put my glasses on before reading the front of the adapter.
Have to admit I wondered how it thought it could fit 3A down those
skinny wires that go to the output plug.
BTW, the Fedco battery packs (3x Gates Cyclon cells in series, held
together with a big piece of heat-shrunk tubing) that I got from iGo
do work. I've ordered another batch from another online seller
(trying to save a few bucks) and will post a note when they've arrived
and I've had time to install them.

I just registered TELETYPE.ORG, and will be putting up a web site with
info about the company and equipment and technology... any URLs of

gotten right now is the thread from TELECOM DIGEST from a few years
back about AT&T's dropping of telegraph service..
Thanks.

Hi:
Well, it's time for spring^H^H^H^H^H^Hfall cleaning, some for free, some not.
I have a Prowriter dot matrix printer in unknown condition (cosmetically
good). Free to the first person who picks it up. No, I will not ship it.
I'm in San Bernardino, Calif. area. It's too big for me to keep now that I
have a new Panasonic 24-pin printer for the C128. It will go to the dump
in a couple of weeks if unclaimed.
I also have two Apple monitors; one, a composite monitor designed for the
IIgs (but works with any Apple II), and a small RGB monitor that went with
my Mac IIsi (15-pin). Both work 100%. I'd like to trade for, in particular,
M100/NEC8201A RAM modules, but am asking $25 apiece or best offer plus
shipping. Priority goes to anyone who can pick them up, since it saves me
having to drive them to the post office. I have Commodore monitors coming
out my ears and since they can take S-video and analogue RGB, they're much
more useful to me than these Apple ones.
The monitors will go to eBay in a couple of weeks if unclaimed.
I'm also not taking any of this up to VCF since I'll be dragging enough
up with me (an SX-64, a Tomy Tutor, several Commodore monitors for them,
all the peripherals for the Tomy ...)

These may not be compatible with the DU-15LU drive, assuming that drive is for
computer data storage and not video recording. Try to compare pictures of the
two types of disks.
Panasonic/Matsushita used to make optical disk video recorders for the
professional market that used 8" disks. The model numbers of the recorders
and players begin with TQ-, so I suspect the TQ-FD22 disks are for the video
recorders.
FWIW, going to eBay and searching for Panasonic TQ should bring up some
listings for the players/recorders. TQ-2026F is a player/recorder, and
TQ-2027F a player. The recording method used by these might be analogue given
their age.

I stopped by a recycling facility today that I had forgotten about as a
possible source. Here's some of the items they had, if anyone is interested
contact me off-list for particulars.
Amdahl - 9406, 6690, 6395. Many of each, about 12 cabinets altogether. The
cabinets were mostly gutted, but the panels were still there. Several
pallets of hard drives were removed but they still have those too.
IBM - 3088. Looks complete. They also had a 4300 that had been stripped to
virtually just the frame. Probably no interest there :)
DEC - a 11/73 chassis only w/power suppy and front panel. A microvax II. An
11/83 turbo. Plus, the following dec modules: M7516-YM, M7555, M7546,
M7606-AF, M7622-AE, M7625-BA, QBUSBEC37

Processor Technology had a HD system they called "Helios",
which used (IIRC) Micropolis hard-sectored disks (they
may have been "firm-sectored" tho). I think most went the
NorthStar route, tho.
I had intended (and still hope) to get a Morrow/ThinkerToys
Discus 2D system for my Sol.

Model 110 is the "HP Portable": 16-line screen, Bell 103 (300 bps)
modem, and no drawers (the RAM size and built-in application set are
fixed). The "Portable Plus" is usually called that, or "110 Plus",
although it has the unwieldy model number of 45711.
The power supply that you probably want (being in North America) is HP
p/n 82509D: it's the same thing as used for a lot of HP's portable
computers, and I think the 41C rechargable battery pack. (There are
other variants on this for places with other input voltages and/or
mechanical wall outlet configurations.) Output is 8VAC, 3A, which
should be applied to the two pins in the rectangular socket on the
back of the Plus (not the trapezoidal ones which are HP-IL
connectors).
If the Plus doesn't hold a charge, the battery is replaceable.
-Frank McConnell
Kevin,
The charger output is 8 VAC. I don't know the current rating but it's
probably about 100 or 200 Ma. HP uses the same charger for a lot of
different things and they can often be found in surplus stores. The part
number is HP 82059. It's a wall wart that's about 1 1/2" on each side.

The worse part is that "agilent" is a very dumb name in many
languages; agile on one hand, "lent" ("slow" in most languages)
on the other.
The measurement/instrumentation half should have kept the
HP name. The agilent oxymoron actually fits the other one.
