Haven't tried it but you could modify this program to dump a optrom. Found on the net. It has some embedded ML to allow safe peek's of the optrom.
I would suggest open com: and print out all characters as numbers with newlines between, transmit to a terminal program, and convert to desired format with a perl or python script. 1 REM --- PEEK OPTION SOCKET --- 100 FOR X=0 TO 13 110 READ D 120 POKE 65351+X,D 130 NEXT X 200 INPUT HL 210 CALL 65351,0,HL 220 PRINT PEEK(63360) 1000 DATA 243,62,1,211,232,126,50,128,247,175,211,232,251,201 https://groups.google.com/forum/#!topic/comp.sys.tandy/jI1HjKOEPAY
