Friend's pin, it may have more issues (hearing there was some smell of smoke when he tried powering it up recently), last time I was able to see the machine with its previous symptoms (basically not working in general, some lights on back box, scramble on score displays, only 1-2 lights on playfield and game wouldn't start) I had thought I had it pinned down to the 5101 on main board. I see there's a few 5101 NVRAM modules available, I'm assuming there's no original/direct IC replacement hence the need for a custom drop in module? Trying to figure out if something more locally in Canada as well for this, to reduce shipping time from US or UK and additional costs.
Thanks!
