I was wondering if this same technique could be used to upgrade >the Model IV's memory from 64K to 128K. Any help would be appreciated. That may have been a trick on the Model III but it is a standard feature of the Model IV. You just fill the empty sockets with 64Kx1 RAMS and you have to add one jumper (don't remember where).
