At the risk of redundancy, I have two questions: 1) Has it actually been determined that you can replace the existing RAMs with new ones (256K I guess) to increase the memory size? The last I had heard on here, there was some question as to whether that was all that needed to be done. 2) It puzzles me that no one has suggested using a desoldering pump to remove the RAMs... I have often used a desoldering pump to extract ICs on our large multilayer circuit boards in our ``mainframe'' machines here, with no problems and no damage either to the circuit board or the chips. The desoldering pumps cost around $12, compared to the cost of cutting out the RAMs... -- J. Eric Roskos jer@vanderbilt
