Help?
This is the single biggest problem (that I've seen) with ESDI
drives over 800MB: These suckers run with a 24MHz data rate.
There are only two ISA controllers (that I know of) that can
handle these: The WD-1009, and the Ultrastor 12F-24.
I purchased a WD-1009 over the holidays, but haven't had the
opportunity to test it. There are two versions of the WD-1009:
One with a BIOS and one without. The ones without are utterly
*worthless* (unless you're using it in a Compaq DeskPro that
supports it).
I don't even want to talk about the 12F-24. These things are
so rare, I've seen maybe one or perhaps two offered on E-Pay
in the past four years.
Q-Bus 24MHz controllers are far more common, but troublesome
to obtain nonetheless.
I was extremely surprised that ESDI's are still being made
(albeit for 'commercial' applications).
