Okay, I studied the file and found there was a difference. The B09
generated file had 1024 bytes of stuff in the beginning of the file that the
disk does not.
So I modified the routine to throw away the first four blocks of ...
whatever it was.
Then I got a file that looks just like the disk. I used DED to look at the
disk and DUMP to look at the file.
This done, I transferred the file to MESS and now I get a NO PERMISSION
error when I try to read it from OS9 in MESS
The ATTR is ----r-wr
I tried to change it to d-ewrewr without success.
This is (at least) a step in the right direction. At least now OS9 can see
Here's the current version of the B09 routing:
INPUT "emulator file.",vfile
INPUT "Disk to read from >/Dx@ ",drive
FOR x=1 TO 4
WHILE NOT(EOF(#inpath)) DO
