Hi,
I am building a small 68000 computer from the ground up. I would
like to build a keyboard interface that would be able to use a pc
keyboard. Does anybody know of a simple circuit design that I could
use. I did find a design some time ago for an XT keyboard interface
using a serial to parallel convertor. Would this still work with an AT
keyboard. A link to a Circuit Diagram or at least a write up on a
circuit diagram would be great.

Thanks

The AT keyboard is yesterday's news -- the new big thing is to use USB
for everything. But the AT keyboard is still less expensive and easier
to apply, and will probably be available for years to come.

So you have the option of complicating your life with a USB interface,
which will let you do lots more than stick on a keyboard, or you may
want to keep things simple with the AT.

Hi Steve,

Two AD603 could do this but I don't know about audio, always used it for
RF. Also, it is way above your power budget.

You should be able to do this with Gilbert multipliers. Check out chips
like the old 1496 or any successors. I don't know that market because I
never use Gilbert cells for dynamic range reasons but I remember people
building audio VGAs with these.

At present I have several threads on ignore. Clearly there is something very
wrong with me to be so completely uninterested in subjects that others find so
fascinating.

I'm not going to attach a name to this description, but I had a mental
picture of a gorilla attacking a truck tire in its cage as an analogy
for some of the s.e.d. threads.

The gorilla starts out curious, but then suddenly flies into a rage,
beating the tire against the bars, twisting it, chewing on it, jumping
up and down on it, howling and generally frightening the spectators.

After a while, the gorilla is exhausted and leaves the tire (the issue
under discussion) lying there, unchanged. The gorilla goes off to take a
nap.

After a while, the whole display starts over again.

Right on the main page, about 5 screenscrolls down (maybe more if you
display fewer lines), under 'A "HOLE" IN PHYSICS', "Fig 1. Energy flux
lines for the nearfield region of a resonant absorber. The tiny absorber
acts like a large disk."

Looks kinda like a monopole, or very much like one of my metaphysical

I thought you meant that there was a specific reference to a Bussard

Nah, just that it uses some imaginary construct to make a big scoop.

Mims and Campbell offer a tour-de-force in their book "Semiconductor Diode
Lasers" ISBN 0-572-00820-1.
They design a laser voice frequency system in there that's good for 3.5
miles. The book also covers modulators, power supplies, receivers, pin
photodiodes, optics etc etc. A really enjoyable read.
Printed in 1972, one wonders how many miles range would now be possible with
the use of modern kit?.

Something like a 'Cyberdyne' or 'Neurodyne' sounds fabulously tekky.

De nada. But the pattern of field lines in the region of the tuned loop
or ferrite rod does look as if the energy is being 'sucked' through the
device. I'll chicken out of trying to do it in ASCII art, though.
