- There is nothing to cut or jumper settings to change if you upgrade a
- Plus from 2.5 to 4 MB. Just replace the 256k SIMMs with 1 MB types.

- (When you upgraded from 1 MB to 2.5 in the past, you already did the
- necessary cutting: as you will notice, resistor R8 on the logic board
- will either be cut on one side, or completely removed. This should be the
- case if any 1 MB SIMMs are used.)
