Do uou need to
add a serial interface to it? I would guess that linking
it to a Centronics output port would be quite simple
Hmm, that could be an interesting route to a solution.
The standard interface uses 7 / 8 bits plus some ready
signals, so it may be indeed possible to use a Centronics
port with a little bit of supporting logic.
I've not looekd at the LA180 prints, but most of the tiem (although not
all the time) it's a matter of inverting singals as necessary. In some
cases you need ot add a flip-flop for the ready signal (set-to-busy on
the strobe nad cleared-to-ready by an acknowledge pulse from the drvice).
Often the hardest part is powering the extra logic toy need. It gets a
bit ridiuclous when you add a couple of '04s to invert the signals and
have to make a 5V power supply for it.
