Macintosh Plus/10

The Macintosh Plus is one of the first Apple Macintosh computers and the first Macintosh I ever owned. The Macintosh Plus is normally powered by a Motorola 68000 microprocessor.

To the right is a picture of the motherboard of one of my Macintosh Plusses upgraded to a 68010 microprocessor. After the 68030 powered Macintosh SE/30, I think Macintosh Plus/10 is an appropriate name.

The 68010 does not bring much improvement, multiply/ divide is supposed to be somewhat faster.

The cpu upgrade is interesting, but Plus/10 is mostly meant as a start to do some hardware experiments with this classic Macintosh.

The bottom side of the upgrade board with plenty of empty space for more hardware is pictured below.
