Porting Sieve Benchmark to Mac

  • by

I play a lot with my PowerBook 100 these days. It’s a part of a large article about early Macs for my main blog (in Czech). PB100 is a cool office machine and it’s always a pleasure to work with it. I mostly run a text editor and a terminal emulator (the 9600 baud connection to a Linux box that can be used for the Internet access). When I need to relax, I have Test Drive II: The Duel (among other games). The Mac version of this game is somehow more fun than on PC even though it displays just black and write pixels.

Anyway, my obsession is to port our Sieve Benchmark to every single old computer I play with. PB100 was not an exception. I already had a version for Mac so I only needed to modify the code to run on the plain Motorola 68000 and System 7.x.

PB100 with a 16-MHz 68HC000 CPU runs twice as fast as Amiga 600 (with no fast memory). That’s not bad. However, my another small laptop from the same era – Toshiba 2200SX – is still three times as fast as PB100 thanks to its 20-MHz Intel 386SX. I’m not surprised that higher-end models (with 68030) from the first generation of PowerBooks were more popular. Still, this PowerBook is my favorite machine among early portable Macs.
