Having the resistor in place indicates 'all 256' I always wondered if you really needed to reconect the resistor when going back to all 256's. (I am not so curious as to take my machine apart to try it..) : Could it be that the IIsi SIMMs are too fast for the SE? I was under the :impression that you couldn't go wrong by installing faster than required SIMMs :in any machine (except that you might have to pay more for them). : It could never hurt for the simms to be 'too' fast : :This is as much as I know about this problem. I am under some time pressure to :get the Mac SE back up and running. If the problem is in the SIMMs/resistor, :then as far as I am concerned the best solution would be getting my hands on :some new 1Mb SIMMs fast. : It should be no big deal to reconnect the resistor. At least when I cut mine I made sure to cut the lead right in the center so that it would be easy the re-connect. I assume that anyone who knew what they were doing would do the same. Apple dealers probably remove the resistor all together... :-)( -- -george george@mech.seas.upenn.edu
