Are you sure it's not jamma? I emailed the seller about that and he said it was (but we all know how that sort of stuff goes). It does have the right number of connections (if I counted correctly). The only problem is that it doesn't have the notch. However, quite a few bootleg, homemade, etc. boards don't have the notch since it's easy to take the key out of your jamma harness (if it's even there in the first place). Anyway, if it really is jamma like the seller says, it leads me to believe that it might just be a hacked console converted to run on an arcade setup. I'm really interested to see what it actually is when you get it.
