  Nope, it's not HP-IL, the only connector that will fit the plug is in the
top of a HP-41. The HP-IL has two connectors, each has two pins and is
trapazodial shaped. One connector is male and the other female. There
are^H^H^H were jumpers cables made to fit them. You have to connect the
HP-IL stuff in a complete loop back to the controller, that's why EVERY
HP-IL device has two connectors.

  Nope, they're out of production but I sell rebuilt ones. There are also
other places that sell rebuilt ones.

  Yes, but the 82059 charger is fairly common.

  No, it's for a security cable to lock the printer down. There was no way
to lock the 41 down. I know, I had two of them stolen. :-(

   In the MAN(ual) position the printer only printed when it recieved a
print command. In the TRACE psition, it printed every program line and the
values in the stack. In the NORM(al) position, it printed when it received
a print command and it also printed when it received a display command.
Several other commands would also make it print in the normal position.

  One of the intereesting features of the printer was that when you were
writing programs on the 41 and the printer was connected and you wanted to
add a comand to advance the paper or to print the X-register, you could
just press that key on the printer and the command would be inserted into
the program! That shows that this printer was not just a dumb output
device but actually part of the 41 system.
