I think anyone who disputes that epay hasn't taken over hamfests is
delusional. That being said, there are still vendors who show up
at the bigger ones (like Dayton and Timonium) and they make the occasional
bargain worthwhile.
As far as classic computing is concerned, I don't see Vax 11/750s
anymore at hamfests: it's all peecees. That doesn't eliminate the
possibility of a mysterious discovery. If the weather is fine (always
a chancy proposition at Dayton), then what is finer than digging
through boxes of junk for the occasional fine item?
Peripherals seem to be in greater supply than processors and cables
abound. So, take the good with the bad.
