Re: Transfer time with ADTgs - 2.5 *HOURS*?

["Mad Martian" <news@madmartian.com>]

I stand corrected! The next day I had the very same problem without touching
the cable since the "fix". Only powered off one day, then powered on the
next! Weird! By coincidence, when I had gotten it to work I had also tried
the Windows version of ADT. It crashed, but I then got the DOS version
working correctly. So when the problem reoccurred the next day, I tried
running the Windows version again. This time it transferred several disks
correctly before crashing. The DOS version then still failed to work at
normal speed, so I stuck with the windows version. It only seems to crash
after trying to transfer bad .dsk files. For now I will just stick with the
Windows version, but both versions appear to have bugs on the PC side not
related to my cable.
