I have the impression that the X1215 is just a rebadged CDC Hawk, i.e. a
normal SMD drive. At least the P825-007/P825-008 is a standard CDC module
drive (see P856M/P857M system handbook pages 17-22 to 17-25).
I was told the card in my P854 is an X1215 interace (and I think the few
notes I have on it -- from Philips -- say that too). The drive interface
is not SMD though.
HP7900 drive does not include the data separator,
it's in the controller.
I had considered using an RK05 or an RK03 in place of the HP drive on an
HP9880 system, this is one thing I would have to sort out (it is not
difficult!).
Me too, but the HP drives spin at 2400rpm instead of 1500rpm. You would
have to modify the controller for the lower transfer speed.
Now that I did not realise. Ouch....
FWIW, I would like the get a 9880 system runnign again on my 9830 and am
slowly colelctign the bits. I how have the cotnrolelr, the 'cables'[1]
etc. I also have a rather batteres 7900. I intend to try to get that
running, but if not, I will have to modify soemthing else to work.
I don't have the 11305 scheamtics (controlelr in that system) to hand,
but fro mwhat I rememebr the write cloc comes from a crystal oscilaltor
,teh read clock from a PLL. I think it's going to be possible to modify
it for a differnet transfer rate, but obviously I want to keep
modifications to a minimum.
