comments..on..

That was the linux stuff, now I have to apologize to .. several, -
sometimes I talk like a jerk, and offend people - like I should be
some sort of a wise guy. What ever I did, ( I du no ) - I sure got
some responds !

But, - to all - what you wrote was very good.

I think I have to study some more - you give all sorts of ideas !

To Ted Robbins - thank you for all the good stuff. This is
something I have wondered about. One electronic circuit will use
this amplitude increase with revs, and generate a tacho signal, -
but I could not quite understand it before you explained it.

What I was looking for was an encoder called STRE 1601, made by
Sensor Techology - but I can't find any company with that name, or
the part. This is the only reference I have to what kind of signal
I should look for.

As for circuit design - I do get your point. But I designed a single
chip to take care of all the stuff, and as for micro controllers -
they can't handle it. Sure for a mice you point and click with, but
not for high resolutions and revs. ( sure - they are cheaper to buy
off the shelf - but once crazy... :-)

I have not been able to read through all the mail yet, - but I saw
some cry outs for Fred and Will from NIST. Do they subscribe to
this list ? If so, - please correct me on the 486 stuff I wrote -
if I have lead these folks astray !
