I am working on porting an ancient DOS program written specifically for a 4.77Mhz 8088. This program uses delay loops specific to this processor, and I need to find out how many microseconds of duration they are lasting.

I have an old Borland Turbo Assembler manual which lists the number of cycles for each 8088 operation, but it's buried somewhere under a mountain of storage boxes.

Can anyone suggest an online source for the 8088 instruction cycles? Or better still, is there some kind of automated utility for calculating the cycles?

Thanks, RD
