Hello.
I think is difficult but... someone could have one Western Digital WD1000
controller in working condition ? I need it for one SGS CP/M system which
comes with one 8" hard disk but without controller.
Some equivalent device with working warranties (including other storage
device) would be helpful too.
Thanks.
Regards
Sergio
Hi
They do rarely come up on ebay but a better option is to get
a TRS80 5Meg hard drive box. It has an almost identical controller
to a WD1000, a power supply and a hard disk in one box.
These are much more common on ebay.
The controller has a couple of extra things. It has an address
decoder and an external signal for a write protect.
The address decoder can just be tied off such that you use
only one line as a select. The write protect signal just
needs a tie off, unless you want to use the write protect switch
on the box.
I'm using one of these boxes on my Olivetti M20 instead of
a WD1000 controller with a ST251 instead of the original drive.
It works just fine.
Dwight
