I'd wanted a sampling scope for some time that I could use to capture signals from say a floppy out or some such. I got what I think is just right. I got a Nicolet 490. It has two channels that capture 8 bit with 200MHz sample rate and two 12 bits at 10MHz. It was broken but it was easy to fix. Looking at the ebay picture, it had not 5 volts. I removed the cover and it took right off. I was figuring to track down a blown tantalum. It seems that it had been dropped once and the 5 volt line that was tiewrapped to the frame was pinched and shorted. I have to fix two of the knobs that use those encoder wheel but have parts on order from Mouser so should be fixed in a few days. It is a 20 year old machine but still really cool. Dwight
