Hi,
I have two of them. I like the DSA, although its huge and not really silent. The most common failure of the acquisition board can be repaired easily.
Mine are those without "A", i.e. without floppy disc. If you have one to part out there are two items I might be interested in: the floppy with its panel and connections & the power supply (one of mine tends to act up).
You're probably in North America, so shipping to Europe would be rather prohibitive.
cheers
Martin
