I was so-o-o-o happy the day I finally got a battery-powered wire wrap tool, to supplement the manual wrapping tool I used. Couldn't ever quite get rid of the manual tool, but having the electric one really helped. Paul ======================================== Paul L.

I built my first "digital machine" in 1959 with discrete transistors - those things in a small metal "can" with 3 leads. 2 transistors + a few resistors & capacitors created a "flip flop" (who remembers THAT term). Connect a bunch in series, apply a reasonably accurate clock, and voila - a digital stop watch! Then I learned Fortran on an IBM 704 and punched cards (rectangular holes, 12 bits per character) and wrote a sort program that brought the "mainframe" to its knees. Given an original Data General "mini computer" with 4K "words" of core memory and a multipass, paper tape, assembly language "compiler", I wrote a data acquisition system, including drivers for the A/D converter and a 7 track mag tape drive. I also wrote a very efficient punched card driver that converted 12 bit Hollerith to ASCII before the next column showed up. (No, not a 4096 entry lookup table - we didn't have that much memory.) This was "remote job entry" in its hayday. Along the way I repaired several "4K word core memory cards" that were about 16" square. Usually it was one of the driver transistors. Wire wrap? - I'm was an expert! Now my wristwatch has more computing power than any of those computers. And I love my Mac!!! David
