Time: 10:24 AM Date: 12/21/90 Subject: Re: AE RumorsMessage-ID: <1 =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Rumors are rumors and I won't believe the Apple II is dead until I see the obituary. I just wish Apple would give us a definite answer on their position concerning the Apple II. If they are gonna drop the machine, I wish they'd just say, "The Apple II has been dropped." Instead they're playing games, feeling the market I guess to see if the Apple II is still profitable to them. Apple's probably making too much money off Apple II sales (gee image that :)) to just say it's over. If this is so, then Apple should continue to support the machine the way it has been supported in the past by Steve the Woz man himself did. Anyway, I still see companies out there like Vitesse, CVTech, Quality Computers and others, doing a good job of supporting the Apple II. Why is it that when Mac and Apple II products are sold by the same company, the company is afraid to even say the "II" word? Is it because the Apple II is better than the Mac? Why is that Apple and Applied Engineering? Later... =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Joe M.

Indeed, the two-phase clock is assymmetrical, >so memory access time is even faster than this. You are mixing apples and oranges. It is not correct to say the two-phase clock is assymmetrical unless you are talking about a particular system. You are talking about a microprocessor that can be designed into a multitude of systems. The system provides the clock, not the microprocessor. In addition, although I am not familiar with the Apple II, the 65xxx systems that I am familiar with do use a symmetrical clock. I used to work at Rockwell as an applications engineer. All the apps notes and applications that I saw there, and the systems that I have designed, use a symmetrical clock.
