I suppose you'd like an original one, but it's just two chips, you
could slap one together.
Michael Holley's site has details, including a PC layout, perhaps
you've already seen that.
I have a SWTPC 6800, but it came with the MP-C. I was thinking of
building an MP-S with an additional baud rate clock, to get a higher
speed than the MP-C.
