A hacker in Germany did it.

He hacked TOS to run with the PAK68 processor replacement board (020
plus 881). He removed alle Line-A calls (replaced them with Line-F) and
dealed with the stack frame.

This version runs with the 010, too. The 010 will give just about 2.5
per cent more performance... I think, it is not worth the effort (the
hacked TOS is incompatible with a lot of programs...).


Pathed versions of a piece of software, you already have a lincence to,
are LEAGAL in Germany. If you payed for a software licence, you are free
to use the software at will; you must not give away your patched
version, but are free to sell the patches.

circle of craning trees, appeared quietly and without fuss a plain white
