First of all thanks for improving PCem

I was testing PCem v15 and noticed 8088 and 8086 machines are running at the same speed (lm20 benchmark showed 4.7 MHz on an 8086 8Mhz).
Hope this is a mistake I made.
Thanks!
EDIT: I tested several roms for 8086 machines, VTech Laser XT3 seems to fail, other 8086 machines are running as expected.
