(some errant programs might crash, but the mainstream is definately compatible.) I think some problems occur when you put in SOME expansion boards that need specific address space or themselves (which the bridgeboard takes for itself) But that is for an owner to answer.. they were made to be 100% compatible. Chips: Old programs will run with 512k chip memory.. they might be slower, or you might run out of memory for some things (you can't have more than 1 640*400*4 screen in DPaint, and have a Music Program with digitized sound playing in the background.. there just isn't the memory. 1 Meg chip ram fixes this) Not many programs will REQUIRE the 1 meg chip.. it's just that some will work better/faster with it in.. automatically, no jumpers/tests needed. Some other features will also just be extensions (the 31kHz "productivity mode" of the new Agnes, 1280*400 resolution of denise) of the OS, and be options in programs... most won't REQUIRE it. -Daniel Richardson Rochester Institute of Technology
