I'm unfamiliar with those two Mac app's but have few suggestions to
offer.

1. With NEC2.68K(SANE), try opening the app. directly, by
double-clicking its icon. With luck you'll then be prompted to type
the input filename. IIRC, this is how Jerry (Gerry?) Burke's Mac
compilations work.

2. Read the NEC2 User's Manual, which I believe is on one of the
unofficial NEC websites. If it's not, ask me and I'll e-mail you my
old MS Word v.5.1a version of this manual.

3. For a very reasonable price you can get NEC2 source and compiled,
executable applications for 68K and PPC Macs from Jerry Burke
<burke2_at_llnl.gov>. For a higher but still reasonable, price you can
get NEC4, within the USA. I've used, and highly recommend, both.
