Thanks Tony,

Without trying to make this thread look like a bad run-on sentence, I have
to ask what is stepping. You can go semi-tech. on me since I have had a
college course in analog and another in digital electronics and a couple of
computer programming courses. My last 8 years have been in PBX telecom. and
Cisco routers so most of what I understand is signaling, propagation delay,
etc. and programming. As long as you don't get too deep I should understand
it.

P.S. How does SL4C9 translate to cC0 stepping. Do you mean that I have to
find another CPU that is stamped SL4C9?

'don't mean to sound like I'm bragging about or trying to look stupid, I
just wanted to give you a reference point that I can understand from.

Basically you are correct in assuming that you need another SL4C9 (this is
the s-spec that is used to determine dual operation compatibility) to be
sure that it will work with your existing processor. There are usually a
few available on ebay - for example there are 4 available on ebay.co.uk at
the time of writing
