ADTCK (ADT CHECK)
for ADT versions 1.21 and 1.22 and ADTGS versions .90 and .91
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.)
