Spoken like a true bean counter :-(

And I know you are not one of those :-)

Cased on the myopic viewpoint ot this group, anything with a market share less than windows, and a 
technical acceptance less than UNIX must be a flop.

This is getting old, can we move on, to something more off topic... Just kidding

BTW: AFAIK the 704 was the first IBM production system to use core memory, the core plane was about
2in square and sat in the middle of a modified 8 tube plugin modual with no tubes.

The 701 "Defense Calculator" introduced in April 29, 1952 and first demostrated in April 7 1953 and the 
702 announced September 25, 1953 and withdrawn October 1, 1954 it had 10k of Electrostatic storage 
using a bank of 84 cathode ray tubes. Decimal digits were stored using charged spots on the display.

There was no 703, guess it never got off the drawing board ?

THe 704 was announced May 7, 1954 and withdrawn April 7, 1960 it was the first binary computer to use 
core memory.

The 705 was announced October 1, 1954 and withdrawn April 7, 1960 it came out with 20k of core 
memory and was a real workhorse..

Go Bears !
