RK05 alignment - without alignment pack?

I seem to rememebr if you do anything to that position transducer, you then have to set up the sin and cos waveforms (it's basically doing repeated seeks of various sizes and looking at signals on a 'scope). The procedure is in the manual, and you don't need an alignment pack (just a 'scope and some jumper leads from what I remember) I have one, but there's no way I am trusting it to the postal 'service' Hmm... If you have a pack recoded on an aligned drive, you might be able to : 1 )Move the heads (relative to the carriage) as far back as they will go 2 Load the pack 3) With a 'scope connected to the read amplifer testpoints (as if doing the alignment with the pack) and the positioner set to cylinder 0, screw in the appropriate algnment screw. You'll see the singal amplitude rise as the ehad gets over the data track, and then fall off as you go past it. 4) Repeat that a few times (note : the screw will only move the heads towards the spindle, unscrewing the screw again will not move the heads) until you find 2 points, one each side of the track, with the same signal amplitude 5) By counting turns of the screw, set the ehad midway between those 2 points 6) Clamp up that head, repeat for the other head. -tony
