On the isa buss (the one in an ibm at), connector b8 is called 0ws, which
suposedly tells the motherboard not to insert wait states when it is pulled
down. since it is no connect on the xt buss, it must insert the wait states
when it is not connected to work with xt cards.
none of my cards connect this pin to anything, thus i assume that they are
using wait states, and actually working like 4.77 mhz xt cards.

i tried just shorting this pin to ground, resulting in a system that would
not boot. no video, nothing.
i dont know if it beeped, because i got rid of my speaker long ago.

is it true that these cards are running much slower than the buss
allows, and is there anything i can do about it?

i thank you in advance for any advice.
