" LaddieAlpha in RequestReadBlock() looks like it would just send back a 0x10 0x00 <CHKSUM> response, but command.tdd notes the read should send an EOF error if the file is finished."
Oh, you're talking about eof error, missed that. Actually that sounds familiar. I'm pretty sure that I fixed a read-past-end issue in my unreleased version. I think that was a bug I fixed while working on getting STARDISK to work (NEC 8401A/8500). STARDISK was reading past the end. -- John.
