Those were sold under the Radio Shack name.  There were also some similar 
and better ones from third parties.

There was a software intensive third party expansion bus serial printer 
interface early on. 
It was supplanted by the TRS-232 (cassette port to serial printer!)
(Not to be confused with numerous other products named "TRS-232")

In Googling for it, I stumbled on
who makes a Model 1 to hard disk cable, a doubler, a CP/M "mapper", etc.
