MULTI-FUNCTION BOARD PROBLEMS
There are memory boards that have DMS (Direct Memory Address)
timing problems which can cause intermittent PARITY CHECK
from time to time or possibly can happen in the future.
The following pgm will test for that condition. If it fails
on an IBM Expansion Board, IBM will replace it. QUADRAM has
acknowledged the problem and will correct it if you call.
25 CLS
30 OUT &H83,1
40 WHILE J>=0
50 J=J+1
60 X$=""
70 FOR I=1 TO 250
80 X$=X$+"x"
90 LOCATE 10,10:PRINT"testing-";I
100 NEXT
110 LOCATE 8,10:PRINT"Times run - ";J
120 WEND
Test your board now to avoid problems later on.
