You are right but it is still the brightness of the screen
that counts in the end. Measured emission is only part of
the end result. Tired phosphors can't be measured without
a photometer or the eye.
Shorts can be opened the same way. Charge a large capacitor
and hit it to to short. Again, a cheaper way.

Wow
I rejuv old '20's tubes all the time. I just do it the
old fashioned way. I'm not all that sure adding a PIC to
the process would mean much.
There is no such thing as a "safer & gentler" method.
You need to bring the cathode to a temperature that
is hot enough to bring new material to the surface.
This always has the chance of blowing the filament.
If done right, this can take from 2 to 20 minutes.
I doubt that running it for, exactly, 19.53 minutes is much
different than 20 minutes.
You run it for a while with the higher voltage then
measure the emission. You are the only one that can decide
when it is good enough. How does the PIC know that
the tube will be bright enough? It might even be over doing
it?? Should it be as bright as new?? Should the emission
value be the only judge??
Why is it that everyone thinks that a computer controlled
or LASER light is better than tried and proven methods.
I guess we all just read the labels and except what some
marketing fellow wrote. There are some things a computer
can do faster than me. It is a little more consistent
than me. But it can be consistently bad as well.
I guess if the computer blows it up, you can say that
it was destined to fail anyway.
Anyway, I thought you were talking about one of the old
fashioned tester/rejuvenators. They just had a meter needle
that was labeled red/yellow/green and a push button labeled
Rejuvenate. I guess I'm just out of date. The ones I've seen
didn't have a PIC in them.

Back in the late 80's I worked in a lab at Michigan State with a dozen or so SunOS
Workstations, 2 Sun Fileservers, and a VAX8600 running Ultrix.
All the Sun machines had odd, short names:
bubo, mala, typh, pock, etc.
It turns out the admin had named them all after diseases, but the management thought
it was too much, so they all became 4-letter truncated diseases :)
The VAX was renamed from sniffles to eecae (an acronym) at the same time.

Well the nubus kinda cards I would bet money on being QMS laser printer

I'm trying to help a guy on the electron microscope mailing list.
He has a LEO 360FE SEM, with a computer attached built by Radstone
Technology, better known for making military and space applications,
he says. It saves images on a Panasonic LF-7300 WORM drive,
but because he doesn't know the embedded OS, we can't guess at
the filesystem on the MO. Any ideas?

Just think, since some of those are subs, (Thresher I know is, I believe
Scorpion is as well), why not name one machine DICASS? For those not in the
know, thats the AN/SSQ-62B Directional Command Activated Sonobuoy System...
And yes, the Navy really *does* call it DICASS... They're death to subs,
usually lead to a direct ping by a dipping sonar, and then the helicopter
crew shouts "weapon away!" and you get torpedoed/depth-charged/all of the
above!

Well, just days after my post regarding XENIX for the Tandy 6000, its
keyboard seems to have gotten some ideas from Jeff's post on TRS-80 keyboard
problems. The 'D' key has taken sick. Every other key on the board works
flawlessly. But simply in the course of normal use, the 'D' key has stopped
working. I've "fixed" it to the best of my ability, but the problem
obviously goes beyond that. Now, that one key in itself wouldn't be so bad,
except that in order to get to the login prompt in XENIX, you have to type
CTRL-D. Which puts my 6000 in the very large paperweight category at the
moment. So my question is - Does anyone have a spare 6000 keyboard lying
around, or know where I might go about looking for one? I have enough
systems lying around waiting for parts to complete them, and I really don't
want this one to join them. Thanks.

Well I've been messing with my H8 some... I did get a program to work that I
entered into the keypad on the front. Now I would like to take the next
step and see if some of the other stuff works...
This machine has the H8-5 serial/ tape combo - I have the cable that
connects the funny Molex connector to the terminal & have a nice terminal
hooked to it. I also have in there what I believe to be the floppy
controller - but I have no cables or drives.
I am assuming that this machine must be "told" via the front panel to boot
>from a tape or disk before I ever get anything on the terminal? Is this
correct?
If this is true - what do I need to get this thing up and running? Will
this thing boot from tape? Is that the easiest option for starters? I am
not having much luck locating information or parts online for this beast...
Also I'm wondering if the floppy drives are just a standard old 360k drive &
some sort of standard cabling that I might be able to round up? If so how
hard will it be to find bootable media?
Lots of questions!
Thanks in advance

I've been reading Stan Veit's History of the Personal Computer
lately. He's got a reprint of the photo from a TRS-80 Model I
ad where a guy is using it on the kitchen table, copying some
thing down on a pad and looking vaguely crazed with a cup of
coffee. A woman stands in the background behind the kitchen
counter, findling a bowl of snacks or fruit and gazing fondly
at the gent in the foreground - as if proud the her man is
finally able to purchase an use a microcomputer. Page 171.

Hi
I'm looking for a good reference book on Pascal.
I'm looking for something in the 1982 to 1985 time range.
The Pascal, I have, is said to be MS-Pascal. I didn't know that
they did a Pascal but it may have been someone elses
that they OEM'd. I don't think it is Turbo Pascal
so don't suggest your favorite TP book.
Of course, it isn't on a x86 machine so there may be
differences. I am mostly interested in the kind of things
one would normally find in the object library that one
would use with this compiler. They mention that it is
a shared library with MS-FORTRAN. Information on FORTRAN
libraries might also be useful.
Thanks
Dwight
> While we're on the subject, did anyone see the article "Data
> Extinction" in the October 2002 issue of Technology Review?
Yeah, but I was somewhat disappointed. The cover made it sound like they
would discuss *media* that would last a long time, but they were just
talking about maintaining the ability for software to handle the data.
That's obviously worthwhile, but it's also much easier to figure out:
1) Use industry-standard data formats, not proprietary formats
2) Use text-based formats where possible rather than binary formats 3)
Keep a specification for the format along with that data, ideally
on the same physical medium
4) Keep the source code for the software that processes the data,
ideally on the same physical medium. Ideally use software written
in a programming language that is widely used, not something
obscure.
5) Keep the tools used to build the binary of the software.
etc.
On the media side, though, AFAIK there is only one high-density
machine-readable media that can be expected with any confidence to last
much more than 20 years. That is CD-R with a gold-coated substrate
rather than silver or aluminum. Note that gold-tinted dye is NOT
sufficient. The main failure mechanism for CD-Rs is oxidation of
the reflective layer, and a gold layer won't do that, so then your limit
is based on other physical processes that occur even more slowly.
Kodak's accelerated aging tests indicated a typical life of several
hundred years, so they conservatively claimed one hundred. They used to
have a white paper on their web site.
However, almost everyone that made gold CD-R media (including Kodak) has
abandoned it. Mitsui appears to still offer it. Of course, it's more
expensive than the cheap stuff by a factor of two or more.
Kodak came up with a "marketing breakthrough" in offering discs with a
blend of silver and gold. They claim these to be better than silver
only discs, though not as good as gold-only. I am very dubious that
these mixed discs will actually hold up better than silver-only, since
there's not actually enough gold to be sufficiently reflective if all of
the silver oxidizes. But I don't really understand the chemistry of it,
so perhaps somehow the mix keeps the silver from oxidizing as quickly?
I speculate, but have *no* evidence, that gold CD-RW media might last
even longer than gold CD-R media. This is because it takes a higher
energy level to cause a phase change in CD-RW media.
If you need to archive data with any media with a limited lifetime
(which means any media at all), you have several potential problems.
You need to recopy the media before it fails, and you need to make sure
that you don't introduce any errors in replication. The longer the
lifetime of the original media, the less of a problem this will be.
When you do recopy the media, you'll probably want (or need) to copy it
onto a different, more modern medium.
One of the things people have worried about is how long CD-ROM drives
will exist. I believe that twenty-five years from now it will not be
difficult to find a working drive that can read CD-ROMs, but that in
fifty nears it will be somewhat difficult. However, one advantage of
the CD format is that it was designed to be so simple that a
microprocessor is not even necessary in a player or drive. This was a
serious design consideration in the late 1970s when Sony and Philips
were developing the CD for audio use, though by the time they introduced
the first actual products in 1983 the cost of a microprocessor was so
low as to make "dumb" CD players impractical.
The CD and CD-Audio specifications are widely available. You can't get
the official specs without paying some money, but they're in IEC 60908
(CD-Audio) and ISO/IEC 10149 (CD-ROM extension) which are *much* less
expensive than buying the Red Book and Yellow Bookfrom Philips.
I believe that building a crude but working CD-ROM drive from scratch
would be a reasonable project for a few grad students, so if it is really
the case that in 50 or 100 years, no new CD-ROM-compatible drives are
commercially available and no old ones still work, it won't be an
insurmountable challenge to read CD-Rs.
If you want a medium with even better longevity than that, I suggest
punched mylar tape. But the density is orders of magnitude worse than
for CD-R.
hi all,
back on the list after maybe a three year absence - nice to see the list is
still going!
anyone know of a good place to post adverts for classic stuff? I'm sure it used
to be frowned upon on this list, and probably still is; I've checked the FAQ on
www.classiccmp.org and it's missing the whole section on list etiquette though,
so I'm none the wiser :-)
(rather not use loot, ebay etc. unless I have to as I don't want the machine
being turned into a coffee table, beer fridge, ashtray etc. etc.!)
cheers

As promised, the results of my shipment of a large
heavy pallet:
The package was picked up on time by the shipping
company selected from freightquote.com's list of
shippers (I took the cheapest). That was Monday this
week.
Delivery occurred this morning (Wednesday), it was
supposed to take 3 business days so they somewhat beat
their estimate.
They did NOT call the receiving party prior to showing
up, but it turned out OK, and everything arrived in
one peice. This was a pallet load of 9 track tapes
and weighed in at 712 pounds.

Does anyone here have the XENIX and/or XENIX Development System disks for a
TRS-80 Model 16/6000? I have a Tandy 6000 that I like a lot, and have been
playing around with for a few months, but the XENIX installation seems
rather spotty. Some command line utilities seem to be missing and the
development tools are missing completely. I suppose the previous user did
that to conserve disk space.
On a related note - If anyone has a TRS-80 Model 12/16/6000 keyboard
suffering from keys that have a lack of bounce, removing the keycap and
stretching the spring out a little works wonders.

Does anyone know anything about this company? Or if it's related to Morrow computers? I found this address on the instruction manual for Morrow convertors. The convertors were super hetrodyne tuners for use for auto radios and would allow the reception of 10-15-20-40-75-80 meter stations.
I found this manual in a binder of Heathkit Technical Applications Bulletins dated 1952/1953. I've never even heard of these bulletins before but they look pretty interesting. Does anyone know more about them or when Heathkit stopped printing them?

I think the necessary connector is a dual row 48 contact 0.156" spacing card
edge connector. I'll have to see if I can find a source. I think some
place like http://www.edac.net would let you specify such a connector, but
actually buying some in low quantities might be a different story.

Did you look at the pictures on http://www.pdp8.net/pdp8em/pdp8em.shtml ?
When I fixed the fuse a while ago I took a bunch of pictures of the
inside of the power supply. If you select the large size you get pretty
good detail.

After that thread about reading various floppy formats under

dmklib, releasing it on SourceForge, and announcing it here, I'm
somewhat disappointed that no one has downloaded it. I was hoping
for some feedback. Sigh.
Hi all,
i bought a HP 9100 A calculator and need some advice.
According to the owner, the power supply hummed and the backlighting
came one - nothing on the screen, though.
I think i should test the power supply and the tube first.
Any suggestions on where i could test voltages and what i should get?
How long would the screen take to light up?
If the calculator is stuck in a loop, would there be a display at all?
Would pulling the logic cards first be a good idea?
Thanks for advice,
Martin
I started with mountain names (heck, everyone does, but then
I *really* like some mountains). But I tried to use
original names whenever possible (citlaltepetl, popocatepetl,
iztaccihuatl, jimulco). Then I followed with aztec deities
(coyolxhauqui, chimalpopoca, tezcatlipoca, huitzilopochtli...).
Nahuatl language is just great for naming hosts.

A while back I was talking with someone from this list about a Packard

So whoever that was, if you are still in need of one, email me, and we'll

I think I have repaired the circuit breaker in my PDP-8/e, but in
my efforts to reassemble the dismantled breaker, I am concerned that
I might have swapped the hot and return wires (black and white) from
the mains plug.
For internal AC wiring, I have seen in this power supply and others
(of the -8/i and -8/L vintage, among others) white and red wires.
Is it white-to-white, black-to-red?
The problem with my breaker turned out to be curable by tightening
up the pivot points of the double-jointed contact-throw mechanism.
The design, it seems, depends on the back-pressure of the movable
contact into the fixed. One breaker stayed extended, while the
other collapsed before the throw was complete. As there is a
linkage that trips both at once, that's all it took. I think there
was excessive side-play that meant the weaker breaker couldn't
stand the pressure at the main joint and it popped.
Before disassembling it, the symptom had been that I could reset the
breaker dozens of times in a row and never have it stick. Now, it
seems quite mechanically reliable. Haven't applied power yet, for
obvious reasons.
Thanks for any tips. If anyone happens to have their PSU dismantled
enough to see the back, I need to know which half of the breaker,
white-lead or black-lead, attaches to the lone white wire, and which
one attaches to the red wire (with a companion wire).
Thanks,
-ethan

Hi,
what is THE favorite terminal you folks here use ?
Now I have all this nice VTxxx I ever wanted, but they always
miss the graphics capabilities, I had on my terminals in the office.
(not talking about GUIs, just few nice lines on the screen)
So, is there something like emulating VTxxx (52,100,200,320,340) and
tektronix ? (probably even 38400 baud ?
I really like to talk about terminals, not software for PC's
emulating those ...
cheers & thanks

Its great to get such a positive response. I have been trying on and off for
about a year to find a new home for this machine as I really do need the
space. I've always thought it was too good for scrap which was why I
saved it in the first place.
Its in two DEC cabinets each 40in high x 20in wide x 30in deep. Once I've
dug it out from under three years accumulated clutter I can send further
details and/or pictures to anyone who is interested. It spent most of its

Once again, thanks for your help.

I recently gained a Pro-350 and a "Robin" VT-180. I know where I can
get various bits of OS for the Pro, but nothing for the Robin. I've
checked the two CP/M archive sites I knew about and done a little
Googling -- I didn't find anything, though I did see a pointer to
Don Maslin and get the impression he may be able to provide disks
for some sort of fee.
Anybody have a pointer to something on the 'Net? There's nothing
like instant gratification, y'know... ;^)

"Chaos will ensue if the variable i is altered..." - SysV Programmers Guide
Well, I grabbed the domain crash.com in the Great Internet Domain
Name Land Grab of the early 90's. So when I'm naming machines, I
have an overpowering urge to use Unix signal names.
The firewall was Segv [.11], is now Hup [.1]; desktops have been
Buserr [.10] and Abort [.6]; web server is Fpe [.8]; main file-
server had to be Io [.23]. The higher numbered signals tend to
vary from one Unix flavor to another, unfortunately... This only
applies to working machines; collection machines are liable to
get boring names like different deities, different pantheon per
manufacturer. I know, I know, how predictable...
In a previous life as IT guy for a smallish ISV desktop machines
were named with input from the user, if they seemed likely to
have a good idea or insisted. Lab machines would typically be
named by vendor and sequence, as they were rotated/replaced on
something like a 12-18 month cycle. The two fileservers I put
together (to get them to stop cross-mounting everything!) got
named Inode and Vnode... External FTP server got named Beyond,
as I recall.
When we brought in a big team of developers and ordered their
machines on short notice, I went with another common theme:
T lines and stops (that's "subway" to those not in Boston ;^)
Servers became Redline, Greenline, etc. Machines became stops
on these lines (Alewife, Copley, Kenmore, Lechmere, etc). The
original plan had been stops for servers and nearby streets
for nodes, but we were rushed...
The name I'm still most fond of is the first machine I was
allowed to name. I started working in the VAX Resource Center
at MIT back in '89 and was handed a VAXstation II, some TK50's
and books, and told to learn VMS from a system managers point
of view (I'd been a user for a couple years). Since I was and
am a big fan of Buckaroo Banzai I called it Yoyodyne.mit.edu
(and YOYO::), and after I finished my VMS lessons it got
reloaded with Ultrix 3.x/UWS 2.x. I got a lot of complements
on the name; several people tried to tell me something about
this Thomas Pynchon guy, but I was more interested in reading
things by Henry Spencer or Rob Pike... ;^)

Well,
- For portability, I like the Osborne 1. I had a Kaypro 4 '84, and I admit
the larger screen was nice, but for 'cool factor', I just like the Osborne.
- For a desktop/all-in-one, the Televideo TS-803 is my pick. The graphics
capabilities are quite nice, and the screen is large for an all-in-one.
Also a nice large clicky keyboard. Wish I had the 803-H, though (built-in
hard drive) :-(. I do also have a Xerox 820-II (a fine machine), but I like
the style of the Televideo case better (not as industrial looking), and the
Xerox drives are external, so they just don't look as nice :-)
- For taking up rack/desk space, I have a CompuPro S-100 system -- Dual CPU
(Z80H and 80286), a separate box containing dual 8" floppies (Qumetrak 842
SS/DS, SD/DD), and a separate box containing dual 5.25" 96tpi floppies and a
40 MB Hard Drive. All of this drives a pristine Heath H-19 terminal with a
sweet graphics board. This is definitely my favorite overall system...
- For a system that runs CP/M that wasn't designed to run CP/M :-), I like
my Platinum Apple IIe w/ Microsoft SoftCard. I had a C-64 w/ the CP/M
cartridge, and I also had a C-128 (which really was designed to run CP/M),
but the IIe appeals to me. Especially the Microsoft CP/M card :-) (from
back when they made good products :-))

I remember hearing the Osborne likened to a VW, the Kaypro to a Chevy, and
the Otrona to a BMW. I had an Osborne and Otrona, while a friend had a
Kaypro. Between the Osborne and Kaypro, I'd probably go with the Kaypro now
-- larger screen, slightly better graphics (IIRC), but it has a strange disk
format that makes copying to other formats more difficult. The Otrona's
still the coolest of the three, and if you can get an 8:16, you can easily
use it to copy disks to/from IBM PC 360KB format.
Desktop CP/M machines (as opposed to luggables) are a different subject, of
which I have little knowledge. Always heard good things about Epsons, except
that they often went down strange proprietary paths and never got much
market share.

And the ever popular Otrona, which I personally consider a little
