There was some project article in Byte way back when, by Steve Ciarcia,
which provided a peecee-type keyboard input (AT rather than PS/2 but that
shouldn't make that much difference). The circuit to deal with this was
very simple and elegant, though I can't remember any more just how it was
done.
He didn't use a UART or similar, though,
just a couple of MSI chips.
And I remember thinking then how it wouldn't be all that hard to stuff an
eprom between the output of that circuit (which gave you keycodes rather
than characters) and have it spit out ASCII.
Perhaps one of these days I'll run across the article again.
Roy,
here would be the list of articles by Steve Ciarcia
http://www.devili.iki.fi/library/author/203.en.html
May you try to find the exact article?
That's an interesting list, and I'm sure that it will help narrow things down
some, but I can't recall from just the title which article it was. The list
will help me omit some of them, though.
A while back I did a serious reduction in a lot of the old magazines that I
had been keeping, and included in that was a bunch of Byte, not the real
early ones, which I still have intact, but that period of time when they
started to get rather bulky. I clipped a lot of articles out and kept them,
and filled nine large trash bags with what I didnt want any more. Somewhere
around here I have a couple of boxes that have those clipped articles in
them, and once I find them and get the chance to go through them, I'll
probably find the article I'm thinking of.
