hello George,
I'm french, I have a Model 200
I think it's identical to the Model 100 for the printer port
I am very interested in your achievement :
diagram, listing (.ino) and others...
my direct mail : f1fco at free dot fr
I am also hamradio : my call is F1FCO
thank you
Pierre, from Nimes, south of France

Subject: [M100] A Model 100/102 "printer"
Although a null modem cable connecting the Model 100 serial port to a PC
can handle some tasks, there are times I need a printer. For instance-
PRINT and SHIFT-PRINT from the panel, LPRINT and variants from a BASIC
program, a .CO that uses any of the printer rom routines such as
assembly listings from ZBGASM.CO with /LP.
My printer (a DMP105) is probably broken beyond repair and I can't get
ribbons for it anyway. This was my plan B:
I used a Arduino Nano clone (AliExpress $2-$3), a foot of 26 conductor
IDC ribbon cable, a crimp-on 2x13F and a USB jumper. The 2x13F goes in
the Model 100 printer port. The USB goes to a PC running a terminal
program such as PuTTY. The Nano is in the middle and its sketch
(Arduino-speak for program) handles the handshake and parallel to serial
conversion and yields a 9600b stream that's the serial replica of the
M100 printer parallel output. On the PC the "printer" output and be
viewed, scrolled, saved, and printed. Not quite the same as a dot-impact
printer but quieter and faster and it doesn't need ribbons.
If anyone wants to give this project a try I can provide a materials
list, a sketch listing, a wiring diagram, and pixs.
