Hi! I have been a fan of JY since it was new and I was a teenager. I bought my machine in 2009 but haven’t been very active in the pin communities the last 5-10 years. I am a purist person and mods are a no-no for me (everyone’s free to do whatever of course). The only ”mod” I added was a Vishay SMD LED panel because i grew tried of outgassing plasmas (but totally hate the grid lines of the other LED alternatives). I might do a write up on that setup if anyone is interested, since it wasn’t as straight forward as one might believe to get it to look right.
I made a teardown last year and wanted to replace the spinner and target decals but it turned out the ”original genuine” decals actually were very off in color as well as other details. I am a graphic designer so I decided to make my own, which I believe turned out better than any repros I've seen. I thought I might share them if someone else would like to use them. The files are here: https://www.dropbox.com/sh/olbwxmqq7fik1rs/AAAClTVvKZvbolyqNDMp4gXia?dl=0
I recommend using the Illustrator files to tweak the colors for a best possible match. I also made a simple 3D printed tool to cut perfectly circular decals, using a #11 scalpel blade. The files for those are included as well.
One last thing, I found an old thread discussing the preliminary manual for JY and there was a link to a scan of it that has since become dead. https://pinside.com/pinball/forum/topic/wtb-junkyard-prelimproto-manual
Do anyone still have the file and would like to share it? I am interested in all these kinds of curiosities regarding the game.
