Memories :)

While I agree that twinax caused many problems, the twinax attached 5251
terminals were solid as a rock. When I was a SE in St. Louis (oh so many
years ago) one of my clients was a mining company. We had 5251 M12s and
attached 5251 M11s down in the mines. PCs (at least at that time, I'm sure
things have changed) couldn't handle all the dust and miner handling, but
the 5251s came through wonderfully.

If the substitute for a dumb terminal is a PC running IBM i Access Client
Solutions (under Windows or Linux), doesn't that mean more work
administering Windows or Linux on all the client PC's?

And, running Windows / Linux on those PC's adds further points for software
failure?

Ha! My dad was an expert at soldering and taught me not to do that. :-)

One day while trying to get a new Twinax across the office we were up on
the mezzanine looking across the top of the office ceiling which was just
drop in fiberglass 2x4 panels covered in 6" of blown cellulose fiber
insulation. My Boss tied a bearing to a string intending to throw it
across
the ceiling to the far wall which was open to the warehouse. He threw too
high and hit a building support beam. It bounced back and then dropped
straight through the ceiling landing on the desk of one of the sales guys
who was on the phone at the time. The cellulose crap came down with it
and
the tile. Soon as the call was over he 'uttered words' :-) :-) :-)

Larry,

I can add to that. How about putting your arm down on the paddle
Soldering arm?

People today have no idea how good they have it. Back in my day, I ran
the cabling, did all the connections, made the configuration changes and
everything else needed.

Once everything went IP, everything has been a million time better.

Jim

You MUST have known different people than I!! There were only a million
ways to mess up twinax. Some of my favorites:

Connect a terminal to a non-grounded outlet. Eventually it fed 110V back
up the shield of the twinax, dumfounding all devices on the string. (AND
Shocking the hardware guy that came to swap the printer!)

Leave the extra twinax cable length laying on top of a fluorescent light
fixture. Every time the light was turned on or off the surge would
clobber every terminal on the line.

People who rearranged their office or desk and disconnected the terminal
taking down everyone on the string. Several times they just yanked the
twinax out of the connector.

Cleaning people who while cleaning disks would inadvertently flip
switches.

Guy hanging picture in the hallway with long screw that radar locked on
the twinax in the wall, shorting it out. Yeah took a while to find that
one!

Seriously in every place I worked with Twinax (and there were many)
problems were routine.

Once it was migrated to active patch panels using Cat 5 and baluns it
got a lot better as for the most part screwing up one terminal screwed
up JUST that one terminal but it still was far from 'rock solid
reliable!'

Unfortunately, twinax is no longer supported on current hardware.

You can do still do 5250 emulation. While still fully supported, it's
rather antiquated and not something I would try to get into now.

Hello,

(Very!) many years ago I worked with a s/38 using dumb char-based
terminals (including op console).
It was a successful setup.
Everything was very simple, and very, very reliable.

Now I am in a position to influence some IT.

So, my question:
Does the system i (or whatever the S/38 is currently called today)
allow
for simple dumb terminal, twinax connectivity?

Best regards
