Epson HX20: Pinouts to Connect a Macintosh



TOPIC -----------------------------------------------------------

I have an Epson HX20 laptop computer and I want to connect it to my Macintosh.
What are the pinouts for a cable to connect the two?

DISCUSSION ------------------------------------------------------

Here are the pinouts for building a cable to connect a Macintosh Plus,
Macintosh SE, or Macintosh II to an Epson HX20 laptop computer.

The Epson HX20 has a DIN 8 connector for the RS-232 signals out. The pin
configuration is:

Epson HX20 Serial Port (DIN 8)           Macintosh (Mini DIN 8)
