  Hello everyone.

  I have an Alphacom Aero printer, which basically emulates an Epson
MX-80.  The parallel port is basically standard Centronics.  It works
fine when connected to my C64 thru a serial-to-parallel converter,
but I can't get it to work with the Amiga through the parallel port.
  I built the cable just by getting out the pinouts of the Amiga and
printer-end ports, running D0-D8 straight through, and connecting 
DRDY, ACK, BUSY, POUT, SEL, RESET, and signal ground to their counterparts
on the other end.  It still refuses to work with WordPerfect.  I haven't
tried just LISTing a file to it from AmigaBasic, but I suspect that
won't work either.  Is a parallel cable supposed to do much more than
just feed signals through?  What am I doing wrong?

  Thanks.
