For nostalgic reasons, I have wanted to acquire two particular disk drives
for a PDP-11 of mine... I don't remember what they are called or what brand.
But - there are two of them in the very far right of the symbolics rescue
picture at the top of the rack with light brown trim line across the front.
Can anyone tell me what those are - and if there are any around to be
obtained? How hard are they to work on? Is the positioner based on patterns
on the drive or a glass reticule?
They look like DEC RK03's to me. Predecessor to the RK05, and actually
re-badged drives from some other manufacturer, the name of which escapes
me at the moment. RK05's used a glass reticule for positioning. I think
that on-disk format tracks came with the first "Winchester" sealed drives.
