Seller's description: "A vintage Micro Switch keyboard is up for auction. However, issue may be with the space bar. Either the pins are broken or the area on the board since I'm not able to put it back on. I do not want to damage any further."

BIN $45.00 (OBO) + 10.00 shipping

Does look like a nice Hall Effect board, but my only hesitation is that the Hall Effect switches I've seen have 4 pins on the bottom, while it looks like the PCB for that board has 3 holes per switch.

Not sure what the date is, I was under the impression that the '8313' sticker was usually YYMM, so 1983, month 13? Dunno about that one.

Maybe we can get the seller to take a picture of the back

Hall Effect switches only need three pins though. Power, ground, and data. I'm still with you on the hesitancy since most of the HE switches I've seen do have four pins, as they include redundant data pins, just saying that only having three doesn't automatically preclude it being an HE board.

Ah well, hope whoever got it enjoys it!

And another photo that includes the seller's feet! I hadn't noticed... That seems to have become a special point of discussion here.  :?)

Hahah, I didn't even notice that! I need to be more observant.

Anyone here get it?

If a seller's feet are bare, do you think it can be an indication they're particularly willing to haggle? They may be eager to raise some dough so they can buy some shoes.
