I have an IBM 1389194, which is a 122-key model M, apparently for a 3192 G
series terminal, with APL keycaps. I do not have such a terminal; someone
else separated the keyboard from it.  I wouldn't mind getting a 3192
terminal, but I'm not willing to spend much money on one.

I'm converting it into a USB keyboard, but I'm doing it in a fully
reversible manner.  If I burn in hell, I hope it's not because of modifying
this keyboard.

If you still have a MAC plus handy you can experiment

by making short programs and viewing them in hex.

You can build up a translation dictionary that way.

I've done that for other Basics in the past.

You show 16 bit values, be careful they are sometimes

byte swapped. The original encoding is most likely bytes

and not words in size.

Do you want complete terminals and keyboards? The reason they like the 
keyboards is because of the feel of the typing. Sometimes they come with the 
monitors, and they have no use for them, so they get dumpstered. If you look on 
elecshopper.com I did have about 20 of these heavy old boards, but none at the 
present time. I do know where some of the monitors are, but not keyboards.

Re: Serial keyboards

2017-06-06 Thread Santo Nucifora via cctalk
I think I'm gonna get in trouble for this answer but while I am not a
keyboard collector, I do buy keyboards when the opportunity arises.

In my particular case, I started out with occasionally buying computers
with missing keyboards because they were inexpensive; far more then when
they had the keyboard.  I would wait for the keyboard to come up for sale
(hopefully) and try to buy it.  Sometimes, the keyboard cost more than the
computer system.

I tried to find out what the fascination was because there couldn't be that
many people looking for the keyboard to complete a system and found the
keyboard enthusiast forums.  I posted some info about my IMSAI IKB-1 (the
War Games keyboard that was matches with the early IMSAI 8080 in that
movie) because it was being discussed as almost being mythical.  I then
started posting pictures of my other keyboards.  These guys collected
keyboards while I collected computers and most came with the keyboard for
free.  I had a built-in keyboard collection.

Yes, there are many who collect mechanical keyboards because they are
interested in the construction of the key switches and the key tops.  As
with anything, the old adage goes, "They don't make them like they used
to".  Keyboards made today are garbage.  They are rubber domed keyboards
with cheap key caps that yellow over time and the type face literally wears
off.  The early construction is top notch in many cases and far superior to
what is available today.  Many of the early keyboard manufacturers have
gone to thin rubber keyboards.  Consider IBM.  The PC and terminal
keyboards could be used as weapons. Today, they crumble.

I am not making excuses for keyboard collectors because they are orphaning
terminals and computer systems that they go with.  I even posted an analogy
that they could understand.  There are people who collect key switches and
key caps only.  They don't even keep and cherish the keyboard these parts
come from!  I stated that a keyboard collector to a computer collector is
like a switch collector to a keyboard collector.  It goes down to that
level.  These switches and key tops are reused on new mechanical keyboard
construction projects.

This is where the Dolch PAC fits in.  The Dolch PAC fits into the key
switch/key cap collector's realm.  These Dolch key caps are used for other
projects because they fit new key switches.  In fact, Massdrop has a
replica set for sale here:https://www.massdrop.com/buy/dsa-dolch-key-set

I bought a Dolch PAC to collect because I wanted to see the keyboard to see
what the fuss was about but mainly because it had Network General's Network
Sniffer software and a full set of manuals.

Sadly, we have to compete with keyboard collectors.  There are lots of
systems without keyboards.  Just last night I reached out to someone with
an IBM 5251 terminal with, you guessed it, no keyboard.  Ad here:
https://westernmass.craigslist.org/sys/6162646378.html  I do have a small
collection of terminals and am trying to save that one from destruction but
it will cost a fair bit to ship and the seller wants it picked up.  If
anyone can save it, please do.

I have also helped out some people who needed a keyboard.  I swapped a
non-working Zenith Z-100 keyboard for my working keyboard with someone from
the Yale library who was an archivist.  It allowed them to get their Z-100
running and archive some diskettes.  I've also bought some keyboards that I
have been able to pair with their systems and have functional examples
again.  In the case of the IBM 5251, I bought the matching keyboard from
someone in Greece, if I recall, a couple of years ago.  This, however, is
only a small part of my collecting.  I also now occasionally buy keyboards
that are interesting.  They are mostly worthless to keyboard collector and
they don't go with systems because they are newer but they are pretty cool.


So that's basically the story.  They collect keyboards like we collect
computers.  I don't agree with what they do and I make that clear whenever
I get the chance but they collect something and I can't fault them for
that.

I hope this helps explain the keyboard phenomenon.

Santo

Just business. Its made worse by the fact that DEC keyboards were considered 
reliable, and cheap compared to the terminals and so often discarded, but the 
terminals kept s spares.
I believe that the later PS2 variety could also be used on a PC with emulation 
software. Good keyboards are rare...

"Over the odds" implies that its over the market value. The odds are that a 
good DEC terminal keyboard will go for "top dollar"..

The binder/oxide is quite thick on them. The only thing they can't survive is 
surface damage that roughens the surface
to the point where the heads crash. I had a couple I was working on recently 
where the plastic catch broke that held the
spring for the door flap and that gouged up the first 1/2" of the top surface. 
I wasn't very happy, since the rest of
the surface was clean.

I hadn't realized it before, but the 2nd generation (2200bpi vs 1100) doesn't 
have write precompensation, and there are
some real kludges in the read recovery circuit to deal with pulse crowding. 
This appears to be particularly troublesome
on the inner tracks. Tuning this is a real PITA, especially on drives used for 
Altos, which pack extra bits on the
sectors for a tag field.

I'm not positive what pack washing machines used.  Distilled water seems

Then again, many electronics are designed to be washed in water (as part of the

Agreed, and packs from the 2311, RP03, RK05 era are washable.  In fact, I
remember a pack washing machine.  And I remember a 1311 pack (from a 1620)
that had hydraulic oil all over it from an actuator leak; it was cleaned
with isopropyl alcohol, as were the heads, and the result was good as new.
All that was needed for repair was a new gasket and a fluid top-off.

If they really are that rare you may want to reconsider.

I have some submerged packs that look like the one in the auction. Wet 
since Saturday :-(




Here's a link to the drive that I'd like to restore some day:

I think I have the same :-)

And I have cables and lots of spare heads: All submerged since Saturday. 
I most probly won't try to recover the packs but I will try to recover 
the heads. Yesterday they still looked good. But still all in water.


We had a disaster... I was not carelessly storing the stuff...

Just business. Its made worse by the fact that DEC keyboards were considered 
reliable, and cheap compared to the terminals and so often discarded, but the 
terminals kept s spares.
I believe that the later PS2 variety could also be used on a PC with emulation 
software. Good keyboards are rare...

"Over the odds" implies that its over the market value. The odds are that a 
good DEC terminal keyboard will go for "top dollar"..
... especially in the UK and as that was a UK link I assume you are in the UK...
