Yes the AMAB3 ROM is tiny. It contains just enough code to read the RDB and load code pointed to by rdb_DriveInit.

The later Series III Supra ROM doesn't use that method. Instead the later ROMs contain the complete device driver. In fact the 3.8b tools disk contains a RemoveDriveInit program to remove DriveInit code from the RDB. Don't run that yourself though, since removing it will prevent your system with AMAB3 ROM from booting!

No need to try dumping memory again since we already got the AMAB3 code successfully.

But it would be useful if you could create disk images (DMS files) for your three floppy disks. Make sure the disks are write-protected. Then use commands like
DMS READ ram:Supra_Boot.DMS FROM DF0: NOZERO
to create a DMS file from each disk.
