I just can't see myself trying to not only wire up everything to support the original hardware, but also diagnosing this Robotron board set I have which is "untested". I figured, skip the nightmare.... get a working game for once!
That was the point I was at with my Joust cocktail -- had an intermittent video issue when I got it, so I fixed that, then I had power problems and fixed those, then I had sound problems that I never managed to get completely resolved no matter what I did, including swapping in good ROM and sound boards. The harness had been hacked apart in a conversion, then hacked back together in the restoration and I was sure that there were problems there.
I decided that I wanted Joust to work more than I wanted to fix it, so I bought an extra board and rewired it JAMMA. If I ever want to sell it (not bloody likely given what it has cost me so far), I'll throw in the original boards, PS and harness so that some other poor fool can spend their time fiddling with them.
I have lots of games to fix ... but some of them I just want to play!
