For PCs, the oldest computer processor we recommend is a Pentium I at a speed of 250 MegaHertz or greater. Any equivalent-speed processor is fine. All Pentium II, III, or IV processors, or later processors, are fine.
For Macintosh, we do not recommend that you use computers with pre-PowerPC processors of 100 MegaHertz or slower. All G3, G4 or later Macintosh computers should do well. OS 9 or OS X work well with Let's Go Learn.
