Thanks! Back in the 1980s, I bought a lot of 43RO machines without the
RS232 module. We made our own RS232 adapter that went in the space in the
back of the printer. The printer had a ribbon cable with a 2 row .025 inch
square pin connector that could plug into different modules such as a
modem, an RS232 interface, and possibly a current loop interface.
