Hi folks,
I'm currently sorting parts of my stuff. And I found out that I have less RK05
packs with 16 sectors (PDP8) than drives. I have some 12 slot packs as well.
But I could need more 16 sector packs.
That, alas, is how it normally is I think i have _one_ 16 sector pack...
I also need a few 24 sector packs, for an HP7900 drive. Those should be
easier to make than 16 sector ones, in that it's 'just' an extra notch
midway between the existing ones.
I have access to some masses of 12 sector packs...
Probably I'm not alone with
that situation.
If there's enough interest it could be possible to machine new center hubs for
the packs. With custom sectoring. I'm quite sure that the biggest part of the
You don't need a complete hub IIRC> The sectorign ring is a separate part
fixed on by 4 rivets. It should be possible to jsut replace that.
Be warned if you do take the bpack apart that the platter is not
automatically centroed on the hub. You ahve to put the platter in place,
fir the clamp ring, then put the hub on a suitable spidnle and use a dial
guage to centre it up. A right pain to do...
cost would be the programming and setup of the CNC
that turns the hubs. Then
Can't anyone turn by hand any more?
