Others that I could bring if I have room or enough interest:
- HP 8660C - Inductive keypad - No converter
- Epson PX-8 - Cherry M8 switches (tactile)
- Quotron 855 - Heavy clicky switches (it's not fully put together, and this is difficult to do, so I'd rather not bring it out of fear of damaging it) - Not sure if it's worth it to convert

- Quantel Keypads - Mitsumi Tactile and faintly clicky versions - No converter
- Sperry-Univac F3W9 - ITW/Cortron Linear Hall Effect - No converter, but one in progress

- NMB keyboard - Tactile and/or Clicky versions
- Amstrad - Spring over membrane linear - No converter
- Harvest - Orange Omron - Clicky - Has issues with the internal controller
- NEC APC-H410E - Blue NEC Alp-like switches
Haven't figured out exactly how many I can bring, but yeah...I still have to carry them. I've excluded some of the massive keyboards from the list, to help

Depending on what I bring, I may bring the parts to build the converters with me if people want to try them out. Haven't really decided on this yet.
