Why not place some Windows machines inside a computer room if they can
run terminal emulation? I think operator consoles of IBM mainframes are still 3270????
Enterprise admins are not jumping through hoops to use 3270 emulation.
Which is strange!! There is nothing wrong about 3270, VT-100 and ANSI.
To secure these old protocols, just box or wrap them with a security shield???
BTW, IBM mainframes (and AS/400 possibly) have communication controllers with security built-in.
Those 3270 emulators are becoming dinosaurs, less secure in protecting
business or risk.ÿ For some time, the two-tier web-based ....

I have not been hands-on close to IBM mainframes since the OS was called MVT, but I am pretty sure that real 3279's are long gone, except in the incarnation of tn3270 (3270 over telnet). And I suspect the console
complex is a PC "service processor". I wonder if it runs OS/2?

Yes, thinkpad with OS/2 Warp on a z seies

Wow! I didn't realize this was still true. I can see the point in using
an OS that's 100% under IBM's control, though.

IBM stopped making terminals some years ago.

I remember the weight of a 3279 graphical terminal when I worked in IBM
World Trade Asia Corp.! It's really heavy and big! :)

IBM moved its Hong Kong HQ to Japan after my industrial placement.
Some said it's because of June 4 1989.
How quickly we forget .... or is it just that sooooo many 'BAD' things
are happening that we forget sooo quickly??
