Thank you all, I've found HyperViper and Line-Up, brilliant stuff. I loved those machines. Those old 80s machines just seemed to have so much character than the new ones.
I've noticed with the generatin of machines after these kind that they all tend to follow the same rules, (i.e. hold after a nudge, 3rd hold). Who came up with those rules, and why does every manufacturer follow them? Anyone know?
