A590 was a typo, I did mean A570. Story behind of naming scheme is prety familiar to me.
Just wondering, how trivial task would it be to get it working? I'm not a interested to have one, just for pleasure of owning. But is there a way to actually use it?
Is it rare?
A690s are kinda rare, as to how easy it will be to get working depends. Some were later prototypes with less bugs than others, the main issue iirc was that some had some form of flash rom to hold the ROMs which tends to die over time.
