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. Standard-IIe-Tender-label.jpg I has some ...

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...

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...

Boxes reminds me of this, which has been up for some time now:

It looks to me like someone took the APL keycaps, put them on their keyboard and put the non-APL ones back into the box.

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...

Writing of design choices for integrated keyboards reminded me that I have this board that I got as part of a package deal from tentator. So I dug it out from the bottom of the pile and hooked it up. Omron-top.jpg The compact layout -- aside from the giant ISO Enter -- suggests a laptop and the Turb...

I got this 1976 board even though it has an obvious problem. VT50-top.jpg Now I'm on the lookout for a Hi-Tek E key or else having to use un corps noir tranchant un flamant as a typing test phrase. Other than that, it cleaned up nicely: only a few scratches and a couple switches with broken corners,...

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 ...

Sanyo MBC-885 with FLS 3rd gen switches:

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.

That could be cool. I've not played with a Space Invaders keyboard before.

I got one a while ago (see here). It's a fun little board.

This keyboard is from a Pericom graphics terminal. Pericom-case-top.jpg It's possible that its model number was 2506. Or maybe that's just the part number for the plastic top of the case. Pericom-case-back.jpg The bottom of the case is sheet steel, so the keyboard weighs almost 2.5kg. Plus it has a ...

KB-5150 label with bad kerning very much like the Chicony in another thread from a couple weeks ago. Except the LED windows aren't the same.

Has APL legends on the front, but they look like decals.

You'd also have a find a replacement power supply.

Suns have the polarity backwards -- idle low -- from modern MCUs, which adds an extra complication that may not be there with this board.

This is back. (Symbolics 365407.)

Looks like the exact same photos to me. You'd think somebody would have bothered to clean it by now.

I got this CAD keypad from RedMarket, whose prices are quite reasonable for some interesting stuff. CGX-case-top.jpg The front is branded CGX, but the back has an Adage QC stamp, so it must have been well after that acquisition had integrated the two companies. The case is dated 6/88 and the PCB 3/8...

A quick check confirms that, indeed, as suggested above, the clocked bit serial signal protocol for the Model II is the same. The codes are different, being mostly ASCII, except that sometimes the shifts affect high bits. From the Technical Reference Manual : model-ii-tech-pg-136.png The same serial...

This keyboard supposedly came from a Morrow MDT-60. MDT-60-case.jpg I have no reason to doubt that, but as far as I know there is no difference in the keyboard itself between that and a Zenith Z-29 or a Heath H-29. The layout is a bit like a VT100, but tries having the arrow keys poke out from the d...

JP!'s recent finds had me taking another look at the SD boards that are sitting around here waiting to have something done with them. This board, 69SD5, is the guts of a data entry terminal for a Burroughs TD-730/830. 69SD5-13-1-top.jpg That is, it is more or less the same board as pr0ximity's in Bu...

I managed to get access to a 98203C, which has both unshifted ( ) for Lisp fans and a k9 key for Tom Baker fans, and fooled around with the macros so that it now works out of the box in the default mapping. In particular, it works to have both it and a 46086A connected at the same time, even though ...

Coincidentally(?) just a few days after a mixed (+ cool looking, + solid build quality, ± weird layout, - crap switches, - doesn't work with Soarer's) review of one of these by Chyros.

Looks like Oak full-travel with blue double shots. And high-end rotary encoder on the side. Missing key probably a deal breaker.

I'd love to learn how do ROM reading. It's all in the data sheet. Start with regular 5V power and a crystal with a couple capacitors. Set RESET low and apply +12V to EA. Put the address to read into DB and a few bits of P2. Then set RESET high, which will latch the address and put its contents into...
