Epson QX-10 help needed

May 18 23:38 UTC 1997

I recently acquired an Epson QX-10 Model Q701A that I know nothing about.
It may be an XT or AT class machine, has dual 5.25 floppies, and round DIN
connectors for a light pen and a  Q702A monitor.
Can anyone out there get me started with pinouts for a standard monitor, etc.?
