It doesn't seem so. My friend timed his 2 Meg Levco Monster Mac against the
Mac+ on a number crunching PC layout program. He was interested to see
whether Apple had used Levco's trick to speed up the Mac+ (the Levco
upgrade was measured by MacWorld to be 23% faster than a standard 512K on
spreadsheet calculations). No such luck. Levco was exactly twice as fast
as Mac+ at number crunching.
