I've got a NEC Multi 2A which unfortunately is one
of the few of
the old NEC's that IIHC won't work with my ST. It has the 15
pin analogue plug and I've heard that adapters for 9-pin are
available. What are the different type of 'chines they would work
with . At present I use a 15-pin ABCD monitor switchbox with my
MessyDoze analogue boxes.
Tho I hate to tell folks they're wrong, but in this case, you may wish to
hear this... the Multi 2a *should* work fine with your ST, unless the 2A
cannot handle negative sync signals. If that's the case, all you'll need is
a one-chip solution to invert the sync signals with (IIRC) a 7404 (or
whatever the hex inverter chip number is... databooks at home, me at work,
and I'm *bad* with remembering numbers).
AFAIR, the 2A *will* sync down to 15.75KHz, which is what the CoCo3, Amiga
and Atari ST require for their video signals. The person who could tell you
more about this is Dr. Marty Goodman... post a message on
news://bit.listserv.coco/ and you should receive lots of good information.
Tell everyone "Merch" sent you.
Hope this helps!
