My money is on them being SM41's, though a few SM51's were also produced
with a pair of round heatsinks.  Dropping them into a SS10 would tell you
for sure.

If you hold the CPU module so that the heatsinks are facing you and the
mbus connector is at the top, at the bottom left corner there should be a
small square oscillator.  SM41's will have 40.3MHz clocks, preproduction
SM45's will have 45MHz, and SM51's will have 50MHz.
