The MK14 used the SC/MP 1 as far as I know, there was all manner of
interface circuitry to  do the appropriate buffering.  I've still got the
original manual at my parents' house,  with a cutout photocopy of the
instruction set  stuck on the front!  For MK14 programming you needed to
learn the hex opcodes, as a result of which I have ever since been able to
"think" in hexadecimal.

I was a programmer rather than an electronics engineer back then, one of my
home-grown attempts at expansion (that DID work mind you) was a stack of ram
chips soldered onto one another, with the chip select sticking out at the
side, connected to a multiplexer chip for the address decoding.  Think I had
8 high at one point.
