Good luck with the trade, you may never know who might be interested given the overlap of media collectors and pinball collectors. One of the first unusual trades I did in the 1980s was to exchange a Toyota Tercel for a bunch of new LaserDiscs.
Our vinyl and wax collection includes Edison cylinders, 78s, LPs, 45s, and CEDs spanning both music and video; and yes, we have old working tech that can play them. For digital media our collection includes CDs, LaserDiscs, DVDs, Blu Rays, and a few DIVXs, HD DVDs, and Ultra HD Blu Rays. We did however pare down our magnetic media and only have some VHS and cassette tapes having parted ways with our reel-to-reel and 8-track tapes to another collector in a trade!
