Subject: My Rodime Wont Spin

 

Having just read the below again more thoroughly, I realised the smaller
ribbon cable was in J1, not J0 (I assume from when I had both the rodime
& WD drive connected at the same time).

 

Now I've moved it over to J0, the format/verify/reformat is running (19 defects
on the first pass).

 

Thanks,
Julian.

I decided to get my Acorn gear out of the loft for an airing.

(looks like C1 in the PSU has popped, I'll follow Sprows' website & list
archives instructions to repair that), but my biggest dissapointment is that
my old 30Mb Acorn winchester wont fire up.

not enough to get it going. Has anyone had experience of dismantling & servicing
these things, or is it a bin-job?

from an old Amstrad PC1640) that spins up when connected to the Acorn winchester

on the unit read 'H4, Wpc 783, Cyl 782, LZ 783, Spt 26'. Can I use this?
I seem to think I have in the past, but that may be a false memory.
