i would be interested in buying one or more faulty ones to reverse engineer annd possibly fix.
the problem with those boards is people just hord them so working ones get more expensive and hard to find.
nobody seems to try to repair them!
Same deal. Can get one any day of the week. I don’t really think there’s a “problem” with people hoarding NetDIMM’s. The price has definitely increased in the past few years but they’re far from scarce.
I have 7 myself don't tell anyone, 3 are GDroom only, two Net Dimm Firm Ver.4.02, two Ver.3.17 but I like to have two of each unit when possible. like you said if they fail they are my backup. I try not to throw stuff away I have a dead taito x2, blue cps2 A board, capcom I/O and cps3 motherboard. I would like to get them fix but I don't know-how and there seems to be no one nowadays that want's to take on that type of work
