Those are the all-important Intel symbol for: "we fixed the ones that were
defective and unreliable and now they run better". Consider yourself
lucky!;) Honestly, the 8080 had trouble until they fixed it and it became
the 8080A, and the 8085 was crap till they fixed IT and it was then the
8085A, and for all I know they simply continued the practice so people
wouldn't call them up and ask them if the chip they had REALLY works right
now or not!!!;-> It may have actually become a higher speed rating, (don't
hold your breath, try 4 to 6 MHz or such!). MOSTLY it means they are
Intel!!;)
