Hi
Received a request for help on a MC68360 prototype board. This is an intermediate step to
the planned MC68040 SBC. If anyone has expertise with the MC68360 and can help please
contact me at LYNCHAJ at
YAHOO.COM or on the N8VEM mailing list.
Thanks!

Subject: [N8VEM: 15020] 68360 help
Hi
I have been working of the MC68360 prototype that would be the precursor to the 68040
build. ?I am stymied and would like any ideas on how to proceed. ?Attached are the
schematics. ?What I observe on power up is that RESTH* is always low - it is pulled up
with a 10K resistor. ? I have tried all kinds of things to figure out why this is so but
can not seem to crack this. ?I feel if I can get past this always low condition I might be
able to make progress would be greatly appreciated. ?I also have a couple of bare boards
if anyone is interested in taking a stab at this.
Thanks in advance?
