I'm just
wondering if anyone knows what a typical value for a single unit
with nothing fancy is? I note a recent auction had two of them together
for
$1400 - Am I correct to imply from that that the
value of an individual
unit
is probably less than $700 (that set was unique
due to the systems being
linked and that control box they had, I think).
A working, complete, 1975-6 SWTPc with top and bezel, original backplane,
original CPU and RAM with an MP-S card is worth $1000+. That would be the
bare minimum system. $700 is too low for a working system. The newer 6809
SWTPc's would be worth less, maybe you can get one of these for $700.
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.
