Low cost assembled & tested 4MB RAM UPGRADE kit for later STF/M motherboards. Fits under the PSU section. It can be switched from 1MB to 4MB for software that will not run on 4MB.

Only fits later revision motherboards such as C070789, Where there are normally 4 rows of DRAM as shown

DO NOT ATTEMPT TO INSTALL THIS UNLESS YOU ARE GOOD AT SOLDERING. IF IN DOUBT GET SOMEONE TO FIT IT FOR YOU AS DIAGNOSING DAMAGED MACHINES IS VERY COSTLY AND NOT A SERVICE I OFFER ANYMORE.
