Z80

Hello everyone! Does anyone, by chance, know what the service life of a subject is? Because today my AOH, who worked with faith and truth, died without turning off for a little over ten years. And he died very strangely: Since yesterday it started to freeze, and today it almost froze every half hour, and then went completely silent... Experiments have shown that half of the data bus has died on the processor :) That is legs 7...10 work normally, but legs 11...15 log all the time "0" Not even “0”, but slightly higher in voltage. And now I’m interested - the stone burned out because it had worn out its ressyps or was it me who finished him off while I was figuring out what was going on? ;) Alexand

Hello, All! Here's some info I dug up ;) === CUT === I think many of our readers still have warm feelings for the "cars" on microprocessor Z80. Once Spectrum computers (in its various modifications) were the most popular "PCs" in our country. But the famous 8-bit Z80 microprocessors were produced not only by ZiLOG. Since 1977 these The Japanese company Sharp also produced processors. Today Sharp has revisited the Z80 and revived it in an all-new quality - in the form of an integrated circuit on glass. So the first one is done a real step towards creating “leaf-thin computers.” Before this, how we written before (see, for example, the news for October 11), on a glass substrate only peripheral and power circuits were integrated (about LSI integration only there were conversations). The technology that made it possible to recreate the Z80 on a glass substrate is based on process developed in 1998 by Sharp and SEL (Semiconductor Energy Laboratory). This technology is called "CG-Silicon" (Continuous Grain - continuous fibers). The CG structure allows electrons to be transferred at a speed 600 times faster than in amorphous silicon, and three times faster than in low temperature polycrystalline silicon. Microprocessor speed is not will get in the way, won't it? :o) The demonstrated microprocessor operates at a clock frequency of 3 MHz, andManufactured using a 3 micron process technology. During 2003, clock the frequency will rise to 5 MHz, and the scale of the technical process will decrease to 1.5 miron. B In 2005, CPUs on glass will “clock” at 20 - 30 MHz, at 0.8-micron technological process. But this is in the future. Starting this month, Sharp begins produce LCD panels based on CG-Silicon technology with integrated logic circuits for PDA, digital cameras, phones, TV panels. Monthly Up to 2.5 million products will be produced. By October 2003 this figure will increase up to 4 million === CUT === Best regards, Alexey

Hi All! Is there any analogue of the Z80 in nature, but only in small sizes? Bye All!

Press RESET immediately, Konstantin Butorin! On Wed, 24 Dec 03 20:52:57 +0300, Konstantin Butorin wrote: KB> Is there any analogue of the Z80 in nature, but only in small sizes? Z80 is available in different cases.
