Hey Steve,
I don't know if you are still trying to get SuperROM ported to PC-8201
or not, but I have merged in all of my M100 disassembly comments into
the PC-8201 disassembly and was able to find *most* of the calls you
identified below.
Note however the following:
1. The encoding for floating point numbers in PC-8201 is TOTALLY
different than M100.
2. Most of the routines in PC-8201 are using SGL precision vs. DBL in M100
3. Three of the routines aren't available and would have to be dealt
with in some other way.

If there is anyone motivated to help, It would be helpful to figure
out the equivalent calls PC-8201 calls for this list of M100 main ROM
calls.
0x30C2 -> NON EXISTENT ( Load FAC1 with zero). Could use: LXI B,
0000H CALL 0x3DF7
0x31B5 -> 0x321E ( Copy FAC1 to FAC2 )
0x31B8 -> 0x3218 ( Copy floating point at M to FAC1 ) NOTE: DBL in
M100, type of last var in PC-8201
0x31BB -> NON EXISTENT ( Move floating point at M to (DE) )
0x31C1 -> 0x3215 ( Copy FAC2 to FAC1 )
0x31C4 -> 0x31D0 ( Move floating point at M to FAC1) NOTE: DBL in
M100, SGL in PC-8201
0x31CA -> 0x31EA ( Move FAC1 to M) NOTE: DBL in M100, SGL in PC-8201
0x31CD -> 0x31ED ( Move floating point at (DE) to M ) NOTE: DBL in
M100, SGL in PC-8201
0x3469 -> 0x31F7 ( Move B bytes from (DE) to M with increment )
0x3472 -> NON EXISTENT ( Move B bytes from (DE) to M with decrement )
0x34D2 -> 0x326F ( Double precision compare FAC1 with FAC2 )
0x3501 -> 0x329E ( CINT function )
0x3510 -> 0x32BA ( Load signed integer in HL to FAC1 )
0x3513 -> 0x32BD ( Set type of last variable to INT )
0x35BA -> 0x32FC ( CDBL function )
0x35CF -> 0x330D ( Set type of last variable to DBL )
