So I picked this up for 25 bucks today,it didn’t work and the guy said it came from an auction and he didn’t know what it was or how to work it so he didn’t test it lol heard this story before, so I took it apart and cleaned it up on the inside took the analogs apart and cleaned the lenses and blew them out and no crap it works great you can’t beat old sun equipment, I think I have a new sick addiction collecting this stuff
