At last, after years of waiting I finally have one :)
This one needs alot of work, infact the working condition is nothing like the seller described, but it is getting there.
So far I have had to fix the following problems :-
Controls wired upside-down (up is down and down is up etc)
Controlls jittering (replaced ADC)
Game crashes after 4-5 goes (bad sockets and bad 74ls245)
Sound missing in one chanel (dead amp on right)
Speech scrambled and not working properly (bad speech chip)
Music stops half way through a level (bad 6502 code roms)
Terrible monitor picture (partially fixed with reflowing solder joints and replacing some caps that i had to had) Monitor still has foldover on the left hand side, poor focus, unballanced colours and takes a very long time to warm up.
The 2 5volt psus have been equalised.
The connectors on the wiring harness are poor or have been soldered straight onto the pcb header pins, so all new connectors needed.
