deprotected the WCS. It does have a problem tho..one you return from the
program the Amy crashes and you need to re-Kick it. Here it is:

To: John Mesiavech (F) (U) From: Ken Jordan Subj: Write Many Ram:
I still haven't figured out how to write protect the ram but try this: –(in
68000 m.l.)-setsuperstate disable interupts & all dma do a RESET instruction
(this pulls the reset pin so that everything resets except the 68000 which
continues on) -presto- the 64k boot rom will be at 0 and you can write to
kickstart (fc000000) (and read also). If you do this the hit ctrl-amiga-amiga
the machine will see that the kickstart checksum is wrong and ask you to
insert kickstart and WILL reload the kickstart proving that the ram was
modified and gets reloaded. Like I say I am still reversing all of the roms
to figure out just what re-write-protects the KS. —Hope this will help->Ken
