Comments
The Classic was the first affordable compact Mac. Unfortunately, that affordability came at a severe performance cost. Most found the Classic extremely slow. Its pedestrian performance was due in no small part to its 8 MHz 68000 processor, which was far too slow for a computer of 1990 vintage. The max RAM ceiling of 4 MB didn't help matters. Its replacement, the Classic II, addressed many of its deficiencies.
