Re: Dedicated console

Hi Patrik,

I think you can add;

5251 Model 11 - Local terminal and
5251 model 12 - remote workstation and controller

These devices originally for S34, S38 I am sure were also used on AS400

I remember very well that the keyboards were, in my opinion, really great.
The positioning and size of the keys, but most importantly the feel of
the key press.

I was one of the last programmers to have my 5251 replaced with a 3196 and
I fought that day for a long time!!!

Cheers

Don

Interesting read, thanks for that!

My very first AS/400 experience was with a 3487-HC.

Which features did this model have? It's not too easy to find information
about models and sub-models of 5250 terminals today. Hmm.

I've started a table on
https://try-as400.pocnet.net/wiki/IBM_Twinax-Terminals_Overview from what
I've found in the English wikipedia's 5250 article.

If anybody has further information to fill missing fields, or expand the
table, please let me know.

And I find it extremely irritating that no emulator that has ever

enjoyed official IBM support has even come close to the elegant aesthetics
of a 3487,

I don't have 3487, only two green 3486-BGX (one with a tube with a broken
neck — searching for a replacement tube in Europe! Biggest problem is to
find one with the same screen slope. Electrically I can adapt almost any
monochrome tube.), a 3477-HCX, and a 3477 with a white phosphor tube.
Unfortunately, I can't find out the name.

and that IBM has thrown out a connectivity technology as bulletproof as

Twinax.

See fellow commenters remarks. For me, Twinax is by far the easiest
solution for having a console attached. If the machine has Twinax, and
there's a Twinax-Terminal, though.

:wq! PoC
