That's awesome info Frank, thanks! The diagnostic shows two bad roms, and
they happen to be the only two high order roms of the only two rom sets in
the machine (lotus & executive card manager).
Are the rom blanks a common chip? Anyone have images I can download and burn
(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
perhaps I could write a snippet of code that emulates the terminal side of
the HP 264x bootloader rom, so my 21MX's can boot from the 110 :D
