Re: Almost bought a QL

Your recollection is both right and wrong. The 68000 was 32-bit as far as the programmer was concerned so no combining 16-bit registers or other such stupidity but the implementation was a bit less so, meaning that 32-bit instructions might have been slower to execute than 16-bit ones (even internally, not just because of the narrow external data bus). But the important thing was the programming model. The 68020 was the first "full" 32-bit implementation but the nice thing was all your 32-bit code from the 68000 would be ready to run and take full advantage of it.
