-----------------------

Seems to be European centrist. Left out the early IBM's, the early
UNIVAC,
The early desktop Wang Computer.

There toward the end they have that little girl looking up at a
370/m155 and the picture before that has a 360/m20 and a string of
2401 tape drives but they are not credited as being IBM.



-----------------------

We replaced a 360/m20 at Macy's Calif in about 1966. Was a no mag file
360.
All card and paper tape. We replaced it with an NCR 315 with mag tapes.
Worked for NCR in those days. I could not believe that IBM could supply a
360 without tapes. (for the youngsters, was not disk drives as you know
them.)

The Mod 20 was always a niche machine that was dropped into unit
record accounts with a software package that was intuitive for people
who were used to wiring 407 boards.
I never had a mod 20 account myself but I was in them occasionally.
Most were card only because that was what these people understood. If
they stepped up, we sold them a mod 30 or a 25.
Some went straight to a 3125 and VSE after years of hanging on to
cards.

As an aside, the real reason states get rid of punch card voting
machines is because it is hard finding a system with a card reader on
it. (not Bush v Gore)
IBM got out of the card reader business years ago


------------------------------

I still have a couple cases of Tab Cards (only IBM called them some other
name). True on card readers. NCR had the best of them, 2000 card a minute
reader, and hardest to read was an almost blank card, as that show any
slippage. We marketed it, but was made by (senior moment) the main maker
of postage machines, NCR 380. Pitney-Bowes.
