This is awesome. I’d like something like this for Sonic and Rampart.
 
All control has a lot of weight.
From 7 trackballs i selected 3 good sets - erased axes.
Then i replaced all bearings.
With length of 80cm - there is not much room for three players.
Here the most emphasis is on the reverse-engineered controller board for trackballs.
I made them from two photos from ebay :)
 
good, now put some stickers on those eproms.
 
These eproms were the same for golden axe and 4 player DIY IO board...
So they were UV unprotected.
 
I had one EPROMs set.
I erased them and wrote other games on them.
Therefore, my chips do not have "stickers".
 
Yeah, I think the suggestion is to cover the windows up again to prevent them from erasing again.
 
I think what he means is he does not have the windows covered on purpose because he changes the game sometimes using the same roms.
 
exactly, cover the windows - specially as you have a translucent case over them.
 
I still think you are missing his point. He doesn't WANT to cover them because he erases and rewrites them often.
 
then he should bank-switch some bigger roms.
 
At the last exhibition, some people offered me to seal them with colored stickers with game characters :)
But this is only an aesthetic gesture, not a practical one ...
It is possible that I will do so, especially since I already bought EPROMs for other kits ...
The more so that Sonic probably will remain the only cartridge on this platform since it was in greatest demand among other arcades.
 
if you want to have the chips visible, you could use a square of kapton tape - i have seen that before.
i think it blocks u.v.
