What was even more surprising was the ability of the 6502
(bog-standard 1MHz
version) to run at 2MHz. Most 2 MHz Z80s tend to wilt if you attempt to run
then at 4 MHz – maybe the device speed selection criteria are more stringent
these days.
I was also quite impressed with COMAL-80’s timing – it was by far the fastest of
the languages tested and its accuracy was pretty reasonable as well. I’ve never
understood why COMAL has never ‘caught on’ in this country – it’s very popular
in Denmark and is fairly easy to get on with.
