Amkey SNK-58

An Amkey SNK-58 keyboard. Amkey-top.jpg There were a number of sales like this on eBay earlier this year. I am not clear whether the seller had several of them or the one sale kept falling through after closing. Anyway, we got this one. It appears to have been part of some kind of T-Bar brand serial...

This is the Track House Standard IIe Tender Keypad for the Apple IIe. Standard-IIe-Tender.jpg The ink has worn off, but the company name is embossed on the rubber insert in the upper-left and almost visible in the photo, as well as printed on the back label.

Atari keypads

I am not one for games, so I do not pay much attention to vintage controllers or gaming features on modern keyboards. But when I came upon this Atari CX85, it looked a bit more like an actual external keypad and I remembered something about them entering into a joint venture to make the key switches...

NEC APC-H25

This is a keyboard from an NEC APC. NEC-APC-top.jpg The keyboard has yellowed in an inconsistent way, I suppose because of how it was stored before I came upon it. It differs from the one in the wiki in not having stepped key caps for the extra-wide keys. It is dated 56年7月, that is, July 1982, so I ...

This is the keyboard from inside a Beehive B100 terminal. Beehive-top.jpg The wiki has photos by snuci, who has a complete terminal. The chips in this one all have 76 date codes and that has a couple 77 and so is perhaps a little younger. The custom controller IC and socketed ROM aren't quite the sa...

Re: CADAM Function Keyboard

What's inside the right-hand box? It's awfully big to just be a null modem, which is all it seems like would be there conceptually. Among other things, which of the DTE signals from the computer are actually wired up in there? That might tell whether DTR matters. I think a reasonable working assumpt...

Re: Pericom keyboard

Do you have an opinion on the switches themselves? I think I like something with a little more travel. I've got an older ITW in the quarantine queue (that's 75% heavier) that I may end up liking more. The ones on this board also feel a little scratchy. I don't know whether that's because they need ...

This is around when everyone was standardizing on IBM compatibility, so maybe it's XT protocol, unlike the earlier 550, which was just serial ASCII.

A quick check confirms that, indeed, as suggested above, the clocked bit serial signal protocol for the Model II is the same.
