Problems with 65802's in Apple II+..........Bob Sander-Cederlof

Much to our dismay, we have just learned that some Apple II+ machines will not function properly with a 65802 installed.  It is probably the same kind of timing problem that exists with the 65C02 in nearly all Apple II and Apple II+ machines.  We had thought the 65802 would work in all II and II+ machines, but it will not.  It works in my old II, and one of my II+ machines, but not the other one.  We have heard of lots of successful installations, and a few unsuccessful ones.  We have not yet heard whether changing to 74F257's will fix things up, as it does with the 65C02.

If you would like to try this exciting enhancement in your Apple, we are selling the 2 MHz 65802 for only $50 (plus $1.50 shipping, and plus 6.125% sales tax if you are in Texas).  (The price direct from Western Design Center is still $95 each.)  If you want to try it in a II or II+, go ahead and order one; if it turns out to be incompatible, you can send it back for a refund.

I hope we are safe in assuming that anyone who orders such a chip knows how to properly handle, install, and remove CMOS parts.  They are extremely sensitive to static electricity, at levels too small for humans to even feel.  You can kill them with the voltage generated by moving your arm, if you are wearing a synthetic shirt.  You need to be careful, very careful.  It is also very easy to bend the leads, or insert the parts backwards.  I know, because I have done it.  If you want a 65802 but are not confident about the installation, find someone who will do it for you.
