I came across this bit of text after searching extensively:

It lists a large number of the different printers and which cables are
required by what. I noticed a few things missing and a few things that
were inaccurate, but it looks like a good place to start to build up a
list of cables.

I did find my Model 1 and Model II printer cables. The Model II cables are
6ft long, and the Model 1 cables are around 3ft. long. The Model 1 cables
look like they are either aftermarket or home-brew.

Probably easiest to just use a 4 pin DIN to DB25M and just use a generic
serial to parallel converter box for parallel printers.

Looks like there are more TRS80/Tandy printers that use the 34 position
card edge connector than just the LP2. The url above lists a number of
them. There may still not be enough of a demand to warrant making up some
extra cables for those though.

Does anyone know what the pinout for the Model 100's parallel cable
(26-1409) is like? I don't have one to refer to. Heck, I haven't even seen
a Model 100 in person since 1993 or so.
