There's something called Vintage Computer Federation, vcfed.org. They're having an event at the Computer Museum (Mountain View) in August. I don't know how real they are. Rich ----- Quoting James Propp <jamespropp@gmail.com>:
Thank you all for making this 57-year-old feel like a young whippersnapper. I don't get that experience a lot these days. :-)

My first computer was the IBM 650. It had 2000 10-decimal digit words stored on a rotating magnetic drum. Senior year in high school class in applied math in 1959, IBM gave us access to their computer. It was punch cards, card sorters, and line printers.

mine was a: https://en.wikipedia.org/wiki/IBM_1620. it had 20k 6 bit bytes and a https://en.wikipedia.org/wiki/Word_(computer_architecture)#V ariable_word_length

And 60 bit (cdc). I also programmed a univac 418 -- 18 bit 1's complement

You left out the 40 bit machines?

"Will you still need me, will you still feed me When I'm 64?"
I've now lived through:
decimal computers (IBM 1620, IBM 1401) 36-bit/15-18bit-address computers (IBM 7040, IBM 7090, GE635, PDP-10,
DEC-20)
12-bit computers (PDP-8) Microcoded machines (Xerox Alto, Lisp Machines) 1-bit computers (ICL DAP 32x32x1 "square word", Connection Machine) 4-bit computers (Intel 4004) 8-bit computers (6502, Z-80, 8080, 8051 (still used inside "USB flash
drives"!), 6800, etc.)
16-bit computers (PDP-11, Moto 68000, 8086, etc.) 32-bit computers (IBM 360, VAX, 80386, ARM, etc.) 64-bit computers (everyone!)
It remains to be seen if I'll make it to 128 or 256...

Apple To Phase Out 32-Bit Mac Apps Starting In January 2018
Apple will be phasing out 32-bit apps with iOS 11, and soon the company
will make the same changes on its macOS operating system. During its Platform State of the Union keynote at the Worldwide Developers Conference, Apple told developers that macOS High Sierra will be the "last macOS release to support 32-bit apps without compromises."
