A few months ago I bought some Atari goodies
and included in them was the ST.Synchro Express hardware, I already had the software for this program and was delighted to get the whole thing. Problem is I do not know which plug goes from where to where. Obviously it plugs into the back of the Atari via the printer port, an external d/drive plugs into the large socket on the S/EXP hardware, but what goes into the small plug socket next to it? please put me out of my misery and give me some idea what to do.
Thanks in advance. Keith.
