a68 (Algol 68) ?

[Arnold Robbins]

In looking at the Feb 1985 ;login:, published by USENIX, I see that the
1981 tape has something on it called 'a68'.  I am assuming that this is
an Algol 68 compiler for some version of Unix.

Questions:  What machine and version of Unix is this compiler for?
How good a compiler (full language, good code produced) is it?
Can it be (easily??) ported to a Vax (and/or Pyramid and/or 3B20)?
What language is it written it? (I would hope C)

If anyone has seen or used this compiler, I would appreciate hearing from
you.  I will summarize to the net.  I am interested since it may be worth
our while to get the USENIX tape if this compiler can be brought up to date
for the machines we have here.

Thanks!

When taking aim at the ball, it helps tremendously to pretend it's a PR1ME...
