I have just received minix 1.5 from PH and have just started getting
the minix list.  I have found some bugs:
* /dev/port not on boot diskettes
  file on an empty file gives a core dump
  invalid parameter given to term locks the shell
* client3 of amoeba has paren in wrong place
* permission error for root to search d--------- directory
           ...etc...

The ones with * i've read from messages and tried them
Also, I have read some comments in the programs I have gotten from the
archive sites about working around problems with minix.  Lets fix them!

    So here is what I would like to know
Is there anywhere out there a bug report and patch fixes for the bugs in minix.
If anyone could let me know I would really appreciate it.

Also, to start myself on a good foot on the net below I submit a calendar
program which will either tell you the day of the week a date
fell on or print out a calendar for the month.

Soon to come a two player nuclear war game!!!!!!
