New old member. Was a member of the old site back around 2010 (same name now as then), only messed with slots at that time (Bally EM, IGT S, IGT S+, IGT S2000). Just acquired a Game King upright ear'd cabinet. 17" Ceronix monitor upgrade done about 3 years back. It's got the i960 processor with 3 simm slots, so assuming it's the 3902 board. Does not have the "audio" board, game chips are the 2214. No TITO printer, has coin comparator (but capped off), no hopper (but could put one in). I do have some of the common key chips on order for clearing/programming/game changes. I think I read that key chip 20 is a good chip, with 17 a close second.
Obviously, the video quality on the video slots is not the best. With that, what is the biggest upgrade that can be done with this machine? That is, can I swap the tray to a different tray? Is the resolution quality limited with what I've got? (Almost picked up an AVP, but this was a decent deal).
I've done some reading, have a couple manuals, but can't say that I've seen the "down and dirty" short answer to the "upgrade" question. Thanks!
