NO RATINGS
Note about 8051 vs. Z80 vs. X86 - I designed an 8051 project in the early 80's and when time came to buy for production not a one could be purchased for love or money. A little company called IBM had designed 'em into thier new keyboard for a product that was yet to be announced - the IBM PC - and had quietly bought 'em all. I ended up doing an emergency redesign with the Z80 for the project I was working on. THe 8051 is not compatible with the 8080/Z80 and I had to rewrite the code from scratch. Neither is directly compatibe with the x86 family although there were lots of effort expended for code migration from CP/M to MSDOS. I was involved with a few projects to do exactly that migration.
