I picked up 2 Digidesign DSP farm cards at a local Goodwill. They are very clean with no obvious issues or capacitor problems.

I don't know what exactly they do, nor can I test them, but I will offer a full 14 day return policy on them in case they are DOA or do not function as intended.

I have a total of 2 cards, they are slightly different so I listed them separately. I will combine shipping / offer a discount if you want both.
