Was that the one that was fairly similar to Centronics but with some
signals inverted?

Talk of the MX-80 has reminded me of a couple of more obscure models...
The first is the TX80. This, I think is a little older. The mechanism

The MX-80 (and FX-80) were among the least expensive of widely available
dot-matrix printers
"It is interesting that the MX-80 was copied by several other printer
manufactures."
The first printer I owned, ca. 1983, was a BMC BX-80. This printer was
marketed as an "Epson Compatible", and for my purposes, it most certainly
was. Driven by C-64 via the Cardco Card/?+G interface, it was capabl

Nope. DECtape only has one set of heads, so it writes blind.

So which one of the three versions (at least, maybe more) is the 'preferred' ?
