Although note that the earliest SWTPC 6800 used the MP-C card as the
console interface along with Motorola's MIKBUG ROM monitor. This was
all pretty much from the MEK6800-D1 eval kit reference design.
If you have an MP-S card for the console interface then you will also
have SWTBUG, which SWTPC developed and came later in the evolution of
those systems.
Oops. Yes the MP-C, not the MP-S. A working system from the first year or
two would be worth a lot more than $700, MP-C / MIKIBUG. Forgot that I
upgraded mine. I use the MP-S but I still have the MP-C.
