AlphaMicro Systems! Arrgh!
Ah yes - AlphaMicro Systems! I remember that videocassette backup. The newer systems remotely controlled the video recorder as part of the procedure.
On the older systems however.... the video recorder was NOT remotely controlled. So you had to set the video recorder to start recording at a certain time - exactly as if you were trying to record a TV program on a schedule. Then you made sure (tried to make sure) that the backup started shortly afterwards.
Many a happy* day spent searching for the start of the backup which was hopefully somewhere on the tape.
* For a given value of "Happy".
