After INIT 3
A) Plain   : MEM = 16955
B) CMT-64R : MEM = 82481
C) B-A     : 82481-16955 = 65526 RAM usable from CMT-64R

A) Plain   : MEM = 16943
B) CMT-64R : MEM = 82469
C) B-A     : 82469-16943 = 65526 RAM usable from CMT-64R

Thanks for testing and these numbers Sylvain.

To Dave's point, the 12-byte difference is the same length as "DESTROY ALL" plus a length byte. Coincidence?

As the gap (btwn a stock machine and Mike's with MATH ROM) is smaller than I recalled, it appears the MATH ROM likely actually uses a bit more than manual claims, so all is likely as it should be.

Good news and some of us have learned something too.
