It is actually 'completely' true: I was referring to your use of a .COM file to make your executable size smaller on one specific architecture. That is using OS features to make your code appear smaller than it really is and has absolutely nothing to do with comparing the strength of ISA's.

As for using OS calls, IIRC both of you agreed to not use those any more. As such, I didn't feel it needed to refer to them.

Indeed, Intel's 486 and Motorola's 68040 were faster. To be clear here, they were roughly 3-4x faster than the ARM you are talking about. They were also a whole lot cheaper than you claim.

A 25MHz 486 from april 1991 (see could be bought for $3000.

Four times faster, but only about 1.7 times more expensive (yeah, I forgot to use the exchange rate between pounds and dollars - April 1991 puts it at 1.7 pounds per dollar, so the GPB 999 A3010 would be $1698). Seems Intel wins this round

Note that a fast 386 or 68030 should also comfortably beat the 12MHz ARM2. And those were cheaper still.
