Hmmm, I'm racking my brains but I don't recall any external unit. For some
reason I seem to recall both cassette recorders attaching to seperate DIN
sockets on the back of the machine...?
But then again my memory of this is very hazy....it was 1979....

Yep, that's exactly what happened....we obviously got a machine which was
intended for someone else....

Yes, we had the top off ours numerous times.
I remember reading an article on the machine where they went into quite a
bit of detail on the bus....including how to build your own boards.
I *THINK* I recall them remarking how similar the bus was to the SS-50 bus,
BICBW.

Believe me, I know the problem....
