Re: A86: 86 Benchmarking
The speed of the processor is in fact a lot closer to 4.5 mhz due to the
direct memory access used by the screen port. Also, the speed of the
processor varies with battery power. Besides, the tokenized BASIC program I
proposed is translated into the same short assembly code and executed over
and over again, so you get the same net result with much less overhead.
