The first 32 bytes of the ROM starting at D000 are almost exactly the same
from version to version, but there's one byte I've noticed:

]? PEEK(-8186)
0 (][+, original //e)
33 (EDM)
137 (//c v255)
150 (//c v1?)
196 (enhanced //e)
234 (SimSystem IIe)

And this is at the beginning of FPBASIC.  The version I've used is 0.

-uso.
