[COPLIN, Nicholas.]  I don't have a kernal listing.... I don't know where
the SETLFS routine is... have these been published on the net?

[COPLIN, Nicholas.]  I'm writing a disk directory program and want the same
BASIC program to run all IEC equipped CBM machines.  Hence I would like to
know if I'm on a C16 or Plus/4 so that I can peek(lastdev) instead of
peek(186).  On the Vic20 I need to "correct" for a 23 column screen, but
Peek(186) is valid.  I have a programmers reference guides for the Vic, C64,
C128... but no serious books on the C16/Plus4... was there ever a
programmers reference guide released?
