What is this? Post Photos of Mystery Items Here (vintage computers only)

My god...I cannot believe that I might have just found it! (In reference to this mystery terminal search)

Anyone ever hear of a Genesis One G-77?

Genesis One G-77 Terminal

I cannot believe that I might have just found it! Anyone ever hear of a Genesis One G-77 ? On a whim, I decided to (once again) Browse Al ...

So of course, since the internet had so little on this, I HAD to make a website consolidating what little is out there...

Thanks, everyone...the community discussion across all resources led me to this!

Best,

Anybody know what this item from "The Tabulating Machine Company" is for ?
Its oldest item I own now I think (as the company went up in IBM in 1933 if I am not mistaken).

is that it there on the desktop? https://en.wikipedia.org/wiki/Tabulating_machine

Hmm dont think so but it could be a variation of the plate underneath the punchcard, that also has two raised edges.
But would wonder why they would need to loan that out
 
Less of a "mystery" item, as I know what its supposed to /DO/ but more of a mystery company/mystery info situation?

(I know its an 8052AH-Basic 'trainer' board, but i'd love more info, and/or maybe someone who's sussed out the circuit diagram? I've got a bunch of them with the 8052AH-BASIC chips and SRAMs on them, but on pretty much every one there's leaky-battery residue-to-possible-PCB damage on the board opposite the blue edge connector?))

I'm sure you have looked for the TEANEY 88 [as I did]. It is a bit of a stretch, but there is an EE , Dale Thorpe Teaney and he has mentored students who did 8052 Projects (https://digitalcommons.njit.edu/theses/2813/). Perhaps it is his design?

Gawd dang! That's basically the EXACT DESIGN of the board I have, aside from a few component labelling gaffes. (R10/R14 being actually R16/R14, and the Second (rectangular) C1 being actually D1, but that's off the top of my head/what stands out most to me)

This will DEFINATELY help me in figuring out if any of the boards work/if i could re-create a board and just transplant parts over to it/make a repro-board. Since i've got a crappe-tonne of those 8052-BASIC chips and SRAMs and the chips that go with them on the board. Only question now/thing to figure out is what is the purpose of the singular, extra chip on top of some of the boards, mounted on the plexi-covers and running to the board? A 74LS365A chip mounted near the SIP-R1-R8 area of the board... (I'm giving a guess of some sort of clock divider, since it has wires running near the crystal part of the board...)
