Hiya Pat:

Those were the days....I did a lot of 6502 work....remember the chip bug where an address that spanned a page was incorrectly read as the chip picked up the second nybble from the current page and not the next page?

>Did I notice correctly in your profile that you had some assembly experience in the 6502? If I remember correctly, that had the same instruction set as the 6510. I was cleaning out some storage space the other day and came across one of my old reference books on assembly with the 6510. Those were the days, eh.
