I just stuck the .5 meg upgrade from E A Brown into my 520, bringing it up to 1 meg. Everything worked peachy, until I tried to recompile something with Mark Johnson C, at which point MJ's assembler wedged up totally. Everything else works marvelously; the ram's there, the ramtester loves it, I burned it in for an hour with no trouble, Uniterm loves it, other memory-hungry programs love it, etc, etc. The only ill effect is the MJC assembler wedging when I load it up. Has anybody ever seen any effects like this? It seems pretty bizarre to me that making more memory available would cause a program to die like this, but that's what's happening. I tried several backup copies of the assembler, and the older version, but all do the same thing. Any ideas will be much appreciated.
