If you want to swap in a new floppy drive or add memory or what-have-you, it's much easier on some computers than others. S-100's were great in some respects -- just lift the ears and the boards pop right out. Or, drop 'em in the channels and they slide right in. The Mac 8500AV, on the other hand, requires nearly a complete disassembly just to add some memory. --------------------------------------------------------------------- O- Uncle Roger "There is pleasure pure in being mad sinasohn(a)ricochet.net that none but madmen know."
