Tandy Radio Shack Computer Cassette Recorder (TRS CCR) PC Types


GOTO PART 4 (Tandy CCR Repairs)

PART 3: Types of PCs that used tapes to store programs/data via a 5-pin DIN connector interface.

This section is to describe the set of computers that would likely be paired with the Tandy CTR/CCR series, since Tandy included the “special” cable that would be necessary to do so. Ultimately this cable is just a particular means of transferring signals, so savvy DIY users could go directly to the circuits and make their own cable. But having a standard cable convention makes setup easier and more efficient for most end-users.

Keep in mind the CCR are also viable audio recorders on their own, and can function as such without this special 5-pin DIN cable.

For reference, here is what the 5-pin DIN connector looks like.
