ADTCK (ADT Transfer Checker) June 2000 Update Usually, the transfer of the Apple II ADT program from the PC-- the transfer you do at 300 baud-- will go fine and ADT will get BSAVED and work like it should. In case ADT does not seem to be working correctly, you may want to check that the transferred program was not corrupted. ADTCK is a short program you can type in and run to check that you have a good copy of ADT on your Apple II. Type in the program below and save it as ADTCK on the same disk as ADT. Then, RUN ADTCK and check the numbers you get against the checksums listed after the program. (The program displays intermediate sums and a final sum.) 10 TEXT : HOME 20 PRINT CHR$ (4)"BLOAD ADT,A$4000" 40 FOR I = 0 TO 2579 50 Z = Z + PEEK (16384 + I) 55 IF I / 500 = INT (I / 500) THEN PRINT "CURRENT SUM= ";Z 60 NEXT I 70 PRINT "CHECKSUM= ";Z Note: To check ADT.CC, modify Line 20 to ... "BLOAD ADT.CC,A$4000" All of the other versions of ADT create the file "ADT".
