Hello, Alexandr! 02-05-98 at 14:56 Alexandr Knyzev => Yaroslav Kozlov: YK>> And then it disappeared somewhere. I uploaded it to YK>> KIRR BBS, in my opinion it is still there.

If the head is already on the zero cylinder, whatIt’s very likely that the VG will immediately set the signal “head to home” "nom position" regardless of the presence/absence of a disk. 2. If the head is not on the zero cylinder, then depending on the presence of the disk, the "head..." signal will not be semi- chen. This is due to the lack of verification that you whether VG completed the team. 3. If you check for execution, then the program It will just stand up until the disc is inserted. chtd.

Hi Yaroslav! YK>>> a simple printing procedure (I can’t do it any faster YK>>> saw). DL>> share :) YK> It takes a long time to divide.
