No, _most_ Tandy printers were parallel. The computers theirselves had
custom connectors, the other end was a Centronics-34.

The DIN cable was strictly for the Color Computer line. Even the printer
which was almost the Siamese twin to the first Color Computers, the LP-VII,
had the parallel port. And any PC comcrapable will talk to them. The
only "problem" is that early Tandy printers accept a carriage return as
both a carriage return and a line feed -- as the computers use that
internally in text files. Tandy's later printers took a command (later a
physical switch setting) so that PCs wouldn't double-space by sending both
codes. All of the "DMP" printers accept this code, as do the daisy wheels
starting with the DWP-IIB. Tandy supplied a device driver for their PC
comcrapables to prevent the machines (and it works on other PC clones) to
make PCs not send the unnecessary line-feed.

I don't recall the catalog number, but it's in the current catalog.

Two thousand yeare since Bethlehem and still we hear the lie,
that after years of hopes and fears the best part's when we die.
