That's awesome info Frank, thanks! The diagnostic shows two bad roms, and

(or chips I can borrow & copy)?
I just love the Reflection1 terminal emulation. Someday I may have to dig
into the rom format. I was thinking (depending on the size of the roms) that
It is docuemnted!. Let me know if/when you want me to type it up from the
technical manual...
