IBM Keyboard Repeat.

Hi Jerry, Mike and all.

I'm a new guy to this forum so I hope you don't mind me jumping in.
===============================================================
The problem is that the IBM designers made the Keyboard autorepeat in hardware.
There is an actual CPU in the keyboard sending out this rubbish. What would be better
is a simply matrix and allow the program to do repeats if needed, and at what speed you
want allowing ramping up etc. In my opinion it's one of the things (many) done wrong in the PC.

Intro:
I was in this biz a short time ago. My last project was building up a commercial product
8051 / standalone system using the Gecko which I see talked a lot about here.
Wow what a neat little device. Before that it was Durants and way before that it was stepper
motors. I'm frankly amazed at the concept of Hobby use of this sort of equipment. I write articles
(I know - Hard to believe) for Magazines, have been in two books, I do hardware design and write
software. I'm a big fan of Assembler Language. I tinker a lot with Ham Radio and like to build
gadgets. And while this might not be the place for it "I'm available for contract design!" <grin>

As to this home CNC? Bravo to you guys for your D.I.Y. Spirit (D.o I.t Y.ourself)
