I put question marks in that diagam as we have no proof yet, but to date, that diagram has held true in all cases: all Hi-Tek branded keyboards and all Stackpole-branded keyboards have fit that pattern.

Sometimes the front of the grid or the inside of the space bar is branded, but often there's no ...

The first and last appear to be DEC VT100 keyboards. "Another unknown keyboard, this one with Hi-Tek switches." — this appears to be from a DEC DECwriter III. (Note the "Digital" branding on them.)

Why do you say that some are Stackpole? They look nothing like any confirmed Stackpole keyboards ...

Oh awesome, thank you!

The Haul

Last week I snagged some old keyboards from my university's resale store. Each of these was on the $1 electronics table, so each one was $1. Every keyboard came as is shown, none with cases, unfortunately.
