Re: ADT - at a loss...



Hi Joseph,

Thanks for the reply!

Sure, you betcha! :)

> 1) Exactly what model Apple II are you using? What memory size?

A Platinum //e - 128K - it worked flawlessly before and I haven't changed
any of the setup at all on it.

> 2) What serial interface are you using?

Apple II SSC-II card - 8N1 - 19,200 baud

Seems to fail occasionally on any of 4-floppies I have. Fails more so
on the 5.25 drives than on the Uni-Disks.

I've tried sending them back to PC and they won't boot on Emulators.

In this case, it's what is making my freshly ADT'd over disk actually boot.
So it's puzzling that it would transfer everything else seemingly properly, 
just
not the DOS tracks/sectors.
