Grappler+ printer interface

  I realise this may not be the best forum to ask this question, but the
emulator newsgroups seem to be pretty much dead.

  I'm updating an Apple ][+ emulator that I wrote back in 1994. I would
very much like to emulate a printer interface card, such as the Grappler+,
but I never owned a printer for the Apple ][+ I still have at home, so I
don't have a printer interface card that I can study.

  So...I was wondering if anyone on this mailing list happens to own an
Apple ][ with a printer interface card like the Grappler+, who would be
willing to dump the ROM(s) and provide me with details of the I/O locations
used.

  I realise some of you may be against distributing ROM code on the basis of
copyright (I personally feel that discontinued products don't deserve
copyright protection, though I realise the law says otherwise). If nobody
is willing to provide me with ROM code for a printer interface card, I'll
settle for a description of the I/O locations and any other information you
can give me on the operation of the printer interface card, and I'll write
my own "clean room" version of the ROM instead.

  Regards,
  Philip
