I updated my knowledge in the 1990s when the lawsuit was in progress. It obviously passed you by. I have an actual job and don't hang out here just waiting for you to post more nonsense. Are you claiming the CADC didn't have interrupts? Really? Based on what? Can't you just admit you are FOS? Interrupts are not required for a true microprocessors. Polling worked just fine during those days. Even for larger machines. Now it is pretty much needed for real time control. But that is only one particular area. Again, you are either FOS or totally ignorant of what you are writing about. And why on earth are you mentioning the 6502? It was derived from the 6501, which was a 6800 knockoff. Uh, since you have limited means to process information, that means the 6800 was in production before the 6501. And that preceded the 6502. In fact, the 6501/2 was the result of industrial espionage. Seems one of the MOS Tech employees from Motorola brought some key documents with him. That almost killed them. It was around that time that I built my first computer. A COSMAC Elf with the CDP 1802 processor. It was basically a 16 bit version of the PDP-8, down to the way that subroutines calls were handled. Bet you don't have a clue what that means... Biewer might have been of the opinion that the 6502 was a great microprocessor, but he obviously never had to program one. It used 256 byte pages in memory since the index registers were 8 bit only and that was a pain to deal with. Why would anything at the time be designed to be an actual computer? The market was tiny, like measured in the dozens per year, until the Altair 8800. Even then, the production run was measured in the couple of hundred per month at its peak. I am thinking you must have been hitting the Afghani hash a little hard during those years. Your memory is all fouled up.
