A single DEC RA81 was $26,000, MSRP, in mid-1984. At this point, you'd
have to be pretty hard up for an SDI disk to want to pay real money
for one. I have a couple. I don't use them unless I _really_ have to.
They have a 30A momentary surge at spinup, and draw many amps (spec'ed
at 8A) when running. From a megabytes/megawatts standpoint, they are
at the bottom of the SDI curve.
