Hello out there in NET land ...
I am sorry if this has been discussed before on the NET, but I am
bumfuzzled about this one, I also prob. spelled that word wrong, but ...
What is the deal with the clock speed rating on the INTeL co-processor
chips??? My brother just bought a 10Mhz, 0 wait state AT clone. The
dealer claims (along with a few people at our institution) that the
coprocessor runs at (2/3) * main processor clock speed.
My question is: What is the correct answer??? Seems to me that the
clock speed is distributed out of the clock generator to both the
coprocessor and the main processor (8086, 80286, what have you ...).
If you put a coprocessor that is rated (2/3) the speed of the input
clock, you introduce alot of room for timing errors, do you not??
Or am I missing something here??
Thanx for any help. If this is in the interest of the net, post.
Otherwise mail me and I will post a summary.
