I find my RA92 much easier to move around compared to an RA81 or RA90. Is an RA82 the same basic size/weight as an RA80?

From the RA82 Disk Drive User Guide EK-ORA82-UG-001

Width: 44.5 cm / 17.5 inches
Depth: 67.3 cm / 26.5 inches
Height: 26.4 cm / 10.4 inches
Weight: 61.2 kg / 135 pounds
Starting current for 120 volt ac drives: 35 amp peak surge for 4 seconds
Running current for 120 volt ac drives: 7.8 amps rms
Running power for 120 volt ac drives: 936 watts

Please don't give up on that RA82.

I'm still too frustrated to return to repairing it. That whole thread became nothing short of a mess.

Especially like the 1/2 the weight.

Start a new one. I'll behave. :stern::killcomputer:

I realize I'm taking my life in my hands to have the gall to suggest good pricing on something... but I stumbled across this UDA50 cable set today that didn't look too bad. Might be of interest to some of you considering hooking up your RA series drives.

That does look like reasonable pricing if you need one of those cable sets, considering that they aren't ripping you off with the shipping.

I agree this seems a reasonable price.

Indeed, it is a great price. However I found a few years back that CAT 5 UTP with crimp pin headers on the ends will work fine - it has nearly the same impedance as the little 93 ohm coax in this cable. Here is that old thread: http://www.vintage-computer.com/vcforum/archive/index.php/t-18049.html

Also, I have dealt with this vendor ( from Maryand so you know they're honest !). I've bought much DEC stuff from them, and while they do charge me sales tax, they also accept lower best offers often and guarantee many parts to be working. They also often throw in free shipping.
