[GreenKeys] Fwd: Looking for an IBM 2741 or similar

IBM 2741 is a terminal based on the Selectric typewriter, not a Teletype.
I don't know where they all went, but they are scarce.  There was also
the 2740 using a different code but same basic machine.  A forerunner
was the IBM 1050, which was a more modular product - could have printer,
keyboard, paper tape reader, punch, and card reader in any combination.
Since most of the IBM equipment was leased, IBM could get it back and
destroy it when the lease terminated.

Teletype Model 29 was originally going to be an up/low case 6-level 
machine to replace the Model 20 in Teletypesetter applications, but 
apparently nobody wanted to buy them.  So it was changed into a machine 
doing upper case only with one of the IBM BCD codes - 6-level, not EBCDIC. 
Supposedly these were for internal Bell System use only, but I know some 
escaped.

Replacements for the 2741 were the daisywheel printers and the NEC
Spinwriter, which was basically a daisywheel with the type element
being cup-shaped rather than flat.  Then came the typewriter-quality
dot matrix printers, mostly used with PCs rather than in self-contained
terminals.
