> The original SimCity for example lists Intel’s 386SX as the CPU in it’s system requirements.
Not sure where that comes from. The original release box art [1] says it will work on any PC with 512KB of ram. So that's an 8088 running at just 4.77 MHz.
But that's far from the lowest spec port of the game. The Commodore 64 version might have been missing quite a few features (like stadiums, police/fire stations and railways), but the main city simulation loop was there in just 64KB of ram and a 1MHz 6502.
And the BBC Micro/Acorn Election port was even more impressive. Had basically all the features of the full Amiga/PC/Mac version, only missing Music/Sound/Animation. With a 2Mhz 6502 (or 1Mhz on the Election) and just 32KB of ram.
The original release was for Amiga and Mac. The C64 version followed around the same time as the PC version, though apparently the C64 version was the original.
Definitely that was often a solution, but the version I had didn't run on DOS. Not sure whether this was a windows only version I had. Often the problem was ram, extended memory often didn't really work on DOS.
This reminds me of microcity which is a Simcity Clone for the Game Boy Colour.
The author has some great in-depth docs about the design, and how they managed to make a fairly lively-seeming simulation fit into a machine with an 8 MHz 8-bit processor.
O huh. I just learned that SHADOWFIRE on the C64 is able to simulate 50 different characters, by only updating one of them per frame.
So the limit is 50 to fit the refresh rate of a PAL TV.

Don’t know if that could be an explanation.
