There are people who will be nostalgic about their PCs. Those are the people who I think we should welcome. They are like us, but younger. Also lets be honest. There is PC history.
I have some friends joining me at VCF East this year and they're heavy on the PC collecting side. The one guy (who is younger than the systems I believe) has IBM 5150s with ESDI drives and all that, MFMs and RLLs. 8088s, 286s, 386s, 486s, P1's. They all run, and they bring them out to a lot of events. I've given them systems like Tandy 1000RL (w/ Adlib!), Kaypro 4, etc. They probably would be willing to bring stuff next event (let them feel it out this one then apply next.) This is the room from MAGFest: https://www.youtube.com/watch?v=sWr9dmUvCOE They literally ran out of space. They had my NeXT Slab, MEGA ST 2, 2 x IIGS and 2 x Apple IIs undeployed along with lots of other systems stacked in the corner.
