Several companies slapped their names on 620 and sold them as part of
a system; I often use a 620 with Xerox's name on it.  The printer may
have "Diablo" on the back panel or inside the case (the Xerox does).

COM1

I'm don't know what you mean by a "standard RS-232 serial cable", but
you can get the computer and printer to communicate by using a null-modem
cable.  Any decent cable supplier should have one availble or be able to
make one very quickly.  If you want to make one yourself look in computer
books for diagrams or see message 47524 in this group for a schematic.

You're welcome.
