dude, I don't see how the original APC or even APC III
(even with the Software Library Expander board) could
be considered compatible with the later APC IV and
beyond. The later ones were truly peecee compatible,
the earlier ones were anything but. The APC uses a
7220 for graphics duty, probably the same in the III
(can't swear to it though), so right there you're
talking a good deal of incompatibility.
I think it probably unnecessary, but I'd like the OP
to clarify which machine they really have. Sounds like
an APC (original).

Hi, I have an old NEC H03 APC III that has the
inbuilt twin 8"floppies & colour screen. I have
blown the High Tension transformer on the board to
the left of the VDU. Wondering if anyone has parts
for this old beastie. I used it to run EZCAM for
2axis CNC machining & would love to get it going
again.
The APC was part of the NEC PC98 series of machines,
which are fairly
compatible from the first (1980s) to the last (ca.
2000) members of
the series. Technically, a better platform than the
IBM PC series
and marketed under varioius export model numbers,
such as N5220. But
sill the venerable PC 9801 under the badge.
PC 98 was hugely popular in Japan, holding the
majority of the market
for the 80s and much of the 1990s. A note to one of
the Japanese
PC98 user groups should get you what you need.
Members of this family are still in use for various
industrial uses;
lots of manufacturers, such as Mitubishi used them
as controllers for
their iron (I see a LOT of Mitsubishi EDM disks
here).
I'd expect to see a higher prevalence of PC 9801
series gear in Oz
than in the USA, for example, simply due to
geographic proximity.
Failing rehabilitation of your old system, there are
several decent
9801 emulators that run under Windoze that you might
try to get your
software running.
Cheers,
