Interestingly, there is no ROM chip in a PCW. Part

Holy freeholy Batman. Now that's a first for me.
If you want to use some other printer with the PCW,
there was a
serial/parallel interface module that plugged onto
the expansion bus
connector (which is basically the Z80 bus). I have
no idea where you'd
find one.
Gee thanks mate. Leave me hanging. Yes I was made
aware of the interface. But for starters I think I'll
need to worry more about hacking up a ribbon. As if
I'd find the time...
Contrariwise I guess it wouldn't be any big deal to
create an rs-232* interface from scratch. I can dream
can't I?
