in a DVR direct TV satellite receiver
I don't see what's so hard to believe about this one. Also, it's more computer related than arcade.
4 MAME arcade cabinets
and I did not find it really strange I just thought it would be informative cause I know a lot of people who think a very small hard drive is in those things or some sort of ram so when they find out what I have pulled from units I have picked up for like 2 or 3 bucks at thriftstores they are utterly

amazed

.
just thought it might be a cheap alternative for those looking for extra hard drive space to hold all those roms

by the way you did not comment on the other items.
and to keep on topic completely
optical encoder and wheel in that treadmaster (yes I forgot about that because I put it in storage not realizing I will be needing such an animal to build a proper spinner

)
