A Z80 sells for about >$0.75. An 8086 can be obtained for under $10. The trend is disturbing. Well lets see: Item Z-80 860 Ratio Clock Speed 4 40 10 Max instructions per clock .25 3 12 Data Size 8 64 8 Raw performance -- 960 to 1 Price Ratio -- 1000 to 1 On this measurement (which, admittedly has little meaning) it appears to be a wash, although I would much prefer a single 860 over 1000 Z-80s even if they offer equivalent performance! The 860 can be made to look better -- consider 80Mflops vs about .001Mflops, or about a 80,000 to 1 floating point performance ratio. On the other hand, the Z-80 can be a real bargain if all you want to do is test bits and branch (as in the microwave oven). Tom Almy toma@tekgvs.labs.tek.com Standard Disclaimers Apply
