You can use Paul Globman's MEMCHK program, but I think you may need to run it once in each bank.
memchk.200 <https://ftp.whtech.com/club100/pg/pg200/memchk.200> Examines all RAM memory locations and reports any bad spots. memchk.src <https://ftp.whtech.com/club100/pg/pg200/memchk.src> Source code for the above. It's only documented in the assembly source code, but if it beeps once, memory is good; five times, memory is bad. If you haven't got file transfers working yet, MEMCHK is short enough you could type it in: 1 '************************ 2 '* MEMCHK.CO (T200) * 3 '* by Paul Globman * 4 '* Copyright (c) 1988 * 5 '* 1 beep=good; 5 = bad * 6 '************************ 10 FOR I = 63574 TO 63648 20 READ X:POKE I,X:SM=SM+X 30 NEXT 40 IF SM = 10354 THEN 60 50 PRINT"error in data":STOP 60 SAVEM"MEMCHK.CO",63574,63648,63574 1000 DATA 195,116,248,17,0,0,126,71 1010 DATA 47,79,119,126,185,112,194,146 1020 DATA 248,126,184,194,146,248,35,223 1030 DATA 194,92,248,195,158,248,17,116 1040 DATA 248,33,0,160,126,71,47,79 1050 DATA 119,126,185,112,194,146,248,126 1060 DATA 184,194,146,248,35,223,194,122 1070 DATA 248,195,89,248,205,69,79,205 1080 DATA 69,79,205,69,79,205,69,79 1090 DATA 195,69,79 1100 REM END OF DATA —b9 P.S. Does someone on this list have access to edit the MEMCHK entry on Club 100? I added line #5 to the above BASIC loader code in the hope that someone will be able to copy this to update MEMCHK in Globman's program collection. Additionally, it'd be nice if the description added the sentence, "If it beeps once, memory is good; five times, memory is bad."
