I've been asked by a friend on the Exxos Forum to burn him some dual-OS ROMs. No problem, I've covered something similar before on this channel (albeit for the STFM).

HOWEVER, I have normal EPROMs in my STE. How can I test that these work?

Time to build an Exxos STE Dual TOS adapter board & show you how to make & flash 256k dual TOS images, then. :-)
