Test Diablo Model 31 drive and disk pack on a PC (Operation Alto

I must admit I don't normally buy components on E-bay. While virtually all of the sellers I've dealt with have been totally honest and great to deal with, I would rather buy things I can't repair (like components) defective. I remember whea I wanted bulbs for the HP 59306, I could find several companies who could supply them, but only in quntities of 50. Which was rather too many... Many years ago I rememebr getting some little metal collars that you screwed an LES cap bulb into, and the result would fit a midget flange socket. I think they came from 'Home Radio' of Mitcham (now that does date me :-)). They are presumably still made becuase I bought some LES panel lampholders a couple of years back and they turned out to be midget flange hoders supplied with these collars. But that's an expensive way to get them. -tony
