Message-ID: <1991Jun2.005808.1271@husc3.harvard.edu> Date: 2 Jun 91 04:58:07 GMT Article-I.D.: husc3.1991Jun2.005808.1271 Organization: Harvard University Science Center Lines: 19 Hey Folks, I have a (yet another) question regarding simms. Has anyone ever heard of "piggy-backing" four 256K simms on a board to make a 1meg. SIMM? Well when I opened my Mac+ the other day to upgrade from 2megs to 2.5megs that was what one of the simm slots contained. Neither I or the tech who was helping me to install the extra RAM had ever seen (or heard) of such a thing. Does anyone out there know anything about this strangeness? My next problem/question is that my mac isn't recognising the new RAM that I've installed. I've cut the proper resistor and all but the beast just wont recognise the extra RAM. I can only geuss that it might be one of two things. Fist the strange RAM already installed or another piece that I know very little about called a "MaxPlus" made by MacMemory Inc. it is supposed to be some sort of "RAM saver". It is a board that is inserted into two of the ROM holders I know practicaly nothing about this device and would really appreciate and knowledge that could be passed my way regarding the thing. Even a phone number for the company would be helpfull. I'm anxious to get that extra RAM installed and working. Thanks in advance, Thatcher V.Hayward
