Hello, all: Work on the Altair32 emulator is progressing and I'm up to getting the floppy controller code working, but I've run into a snag. Has anyone ever used this controller? Does anyone know if it has a BIOS or something *other* than the 256-byte bootrom? I disassembled the bootrom that I borrowed from the Elena Altair simulator and it seems to reference addresses outside its execution range. Thanks. Rich ========================== Richard A.
