Looking in my archives,  I show (in more or less alphabetical order) the 
following:

EPOXLINK.LZH    Transfer program specific to Osborne Executive (I have one)
EPSLINK.LZH        Transfer program for cp/m machine - same UI as FILINK
(That one is assembly source)
FILINK.LZH           unix equivalent to EPSLINK
PROMFORM.LZH program & doc file for burning eproms

...and a few others.  That "FILINK.LZH" sound like the one you're looking for?

Slackware here.

Ok,  downloading still...

Yes,  I often used a 5-pin for video when working on c64s,  which could have 
either that 5-pin or an 8-pin socket.

I like that kind of thinking!

Heh.

I don't think it likely that I'll be dealing with them.
