Dean, The first thing I should mention is that this 2052 is being used in a Subsystem on a 500, since I have 1 meg internal could we assume that the memory allocation routines would be the same as on the 2000? If not I can test it in a friends 2000 and try to get the addresses. If they are the same then I will try and explain it in further detail. Ok, first thing I tried was two memory test programs, MEMTEST and MTEST-2. Memtest gives me an error at address 002019A2, MTest-2 gives the error at 002019A3. To try and clear this up I got MEd, a memory editor. Going to address 002019A2 it would display; 002019A2: 00 FF 00 FF 00 FF 00 FF (or some combination of 00 and FF) Now, I know it starts out this way when the address is not in use. then I'll go in and put in all 0's, and this is the result; 002019A2: 00 01 00 00 00 00 00 00 You'll notice that address 002019A3 is in error, now I can continue with other values, all 1's comes out ok. All 2's comes out 22 23 22 22 22 22 22 22, again 002019A3 is in error. All 3's, ok. All 4's comes out 44 45 44 44 44 44 44 44. All 5's ok….etc. All A's comes out AA AB AA AA AA AA AA AA. All B's is ok. All C's comes out CC CD CC CC CC CC CC CC ……etc. <continued>
