Just a suggestion - you might try installing Johnny's RPM on a simulated
PDP11 w/FPP first, just to be sure it works and that you aren't doing
something else wrong. Then try building the non-FPP version and replace the
existing TSK file with that.
And a question - do you have an APL terminal too? I think DEC did make
some with the APL character set, but they were very rare. Or is there some
hack for doing APL with standard ASCII (although it would be hard to think
of it as APL in that case).
