Well, if it was me, I'd look for the example After Dark code first, and then find the compiler that it's meant for. I can't recommend any versions, sorry. Don't know about MPW either.

I bought Think C off of eBay a few months ago, but haven't seen much for a while. Never seen a copy of Think Pascal. It might be a long wait.

I don't have any idea (doubt it) if Thin C (based on Think C 2.0 I believe) would work, but it is a freeware C compiler for early macs FYI.
