You've already been given the message concerning the BREAK-RESET on
power-up. I thought I'd mention that that should work fine with the
16k CPU. The 4k CPU won't recognize the RAM in the EI - the self
test will notice that there's nothing past 4k and not look further.
You could write a program to _manually_ initialize the EI memory and
poke values into it, but BASIC can't see it. About all an EI gives
to a 4k CPU is a parallel port and an extra cassette port -- TRSDOS
(or any of the alternates) sure won't fit.
