a lot of stuff from that era seemed to use F0 as the ECM identifier, so that's what i put in.

took a look at the files i have, should be $48. i have a real basic disassembly going on ATCA, all of the BINs are 16KB. the entire calibration fits in from C000 to C7D8. the 8192 baud message starts at C721. the 160 baud message starts at C7A1.

from the code, it looks like the ECM uses F0 as the identifier.
