BERM V1.01
===========
This tool allows to switch to DSack/BERR (Bus-Error-mode)
on a A4000. The default for 030 ist DSack, for 040/060 BERR.
It's a kind of minimal "Enforcer", because the A4000-Hardware
can regconize access to illegal memory.

In DSack-Mode all illeal access are simply terminated, delaying for
170µs. In BERR-Mode an "Illegal Exception" will be called,
if there is no Error-Handler your System will hang for ~1 second.

Usage:
BERM [o|c]  ;default ist DSACK-Mode
If option "o" is given BERR-Mode is selected
If option "c" is ONLY Bus-Status will be printed. No changes are made.

Example:
1> BERM c
BERM: Bus TIMED OUT ! (DANGER)

This means any programm wrote to a memory-location that does not exist.
