MINIX 1.2 looks good; as one person said a month or so ago: although
the kernel for MINIX may be Version 7 compatible, the utilities are
only up to Version 6. The new distribution seems to correct much of
this. Yacc, lex, and uucp are still missing, but...
Anyway, there are still two programs (which apparently have been posted
before) that many people do not have. They are cal(1), and login(1).
In an effort to alleviate this, I wrote a simple version of login, but
it would be nice to get the "real" version posted by ast. Could someone
out there post them?

I also am missing the at_wini.c driver which was recently posted.
Professor Tanenbaum: thank you very much for creating the operating system
I love for the machine I have, and put me down as one of those poor
unfortunate students who can't afford a hard-disk.
