By reading this post the last time it was up, I found out that I most likely have the prototype at home (called A690). The information was on one of the links given.
Now I just need to get the thing plugged in to test. A normal A500 PSU would be enough, or do I suffer from read errors in memory?
Ram shouldn't be a problem since I have 3 or 4 MB installed on my ram card, and I can switch between 0.5 MB chip and 1 MB chip.
I actually think I have an extra ram expansion that can hold more than 0.5 MB, but I think it's broken
