Bill_W: Thank you very much for joining the Intel® Processors communities.
In regard to your inquiry, Intel itself does not have the documents you are looking for available anymore, let me apologize for that. In order to assist you to try to find them, we recommend to get in contact with Rochester Electronics, they might be able to provide the files you are requesting:

Now, I found a link for the data sheet for that microprocessor, it is not an official Intel site, but there might be useful information for you in there:

I hope the information above was helpful for you.
