12425Re: Donner 3500 Analog Computer
- Apr 28, 2009I have two of these...one is a Donner 3500 and the other is a Systron-Donner 3500. They are pretty much alike. However, the one on ebay has three major difference...it doesn't seem to have any potentiometers at the top, the patchboard has an opening for the fan and it has metal handles on the top instead of leather straps on the side. It's also a low serial number and I thought the it might go for around $2200-2400...it actually went for over 2500. You can compare the pictures on ebay with some I have at www.earlycomputers.com.
