Next is a Qume QVT-61 from around 1994. This is what got me started on this set, after doing a few older QVT keyboards that cloned a VT100, sort of.

The wiki has a page on Clones of the DEC LK201 , and a number of them were made by Cherry with MX black switches. After working on some related keyboards, I dug the ones covered here out to focus on. They aren't Cherry boards, but do have Cherry switches. First up is a Wyse WY85, 840105-01, with thi...

Really stuck? Like totally jammed? These boards have a few latching keys in strange places, mind. Can't remember off the top of my head, but I recall a couple maybe up in the function row. Yep, totally jammed. The latching keys are fine but the three normal ones under the nav cluster don't move at ...

The plus is important: the QVT-101+ is a substantially different keyboard. QVT-101+-case.jpg The overall layout is different. It has a distinctive row of round function keys. There are a few even more distinctive Necco wafer colored action keys. The switches are rubber dome. The function key actuato...

The protocol that the terminal used to talk to this keyboard requires loading the previous state of each key before sensing it. Which I think explains why you might want a more vanilla switch for RESET TERMINAL to be sure of getting things reliably back in sync. Baud rate and parity (odd, even, none...

The Qume (ITT subsidary) QVT-101 was a low-cost green screen ASCII (dumb) terminal from the mid-80's. It competed against the likes of the ADM-3A in the sub-$500 market. For ANSI (smart) terminals, in particular with VT100 compatibility, there were other higher-end QVT models. I believe these capabi...

Teensy 3.6 or 4.0 and the USBHost_t36 TeensyDuino library support USB host mode, which is probably the hardest part of this.

1) Maybe the MC7004 is only kindof compatible with LK201, and maybe it's missing some features. I think this is the most likely.

Yes, that's it. A real LK201 has commands to enable key-up for different groups of keys, not just the shifts. The МС 7004 does not support those. More here.

It can connect to a DEC VT-220 and looks pretty much identical to a DEC-LK201AA keyboard. I'd say that the odds of converting it to work on a modern computer have gone up :). I am not sure that one can mix and match keyboard and terminal with a VT-220. The LK201 uses an RJ connector not mini-DIN-8,...

it`s real to connect this keyboard to a modern pc? may be use some converter? How easy this will be depends on what the serial signals are. There are a number of possibilities: ASCII characters -- this makes it very hard to turn into a modern keyboard ASCII characters plus separate indication of sh...

Have you checked out what you will need to get it work on a modern computer? But of course, this is always my goal. The keyboard uses a weird signaling protocol that is documented elsewhere online.

Another case where the advanced UARTs on the 32-bit Teensy's can do work that used to take a bunch of discrete components. The Coleco ADAM peripherals connect via a shared bus called AdamNet.

One of the keyboards that has been waiting for conversion is this from a TI Silent 700 Model 743 (or more likely 745 -- the difference is an acoustic coupler and I think they sold better with), including the APL option: 63SD17-3-case.jpg It has Micro Switch SD series switches. 63SD17-3-top.jpg Most ...

For a short period in the early-80's, some home PCs had infrared wireless keyboards, to try to make them more flexible in non-office setups, I guess.

Is “sctools-master/hidapi” supposed to be an empty folder?

I believe that hidapi is a submodule. Did you do this?

Code: Select all

git clone --recurse-submodules

If not, you'll need to submodule init and update them after the fact in the working directory.

What does the keyboard say when it enumerates to the OS? That might remind you want firmware you put on it.

Did you confirm that it isn't just running Soarer's by trying sctool boot?

Good call on EXTRAKEY_ENABLE. Looks like it got lost in the conversion to the expanded info.json. The stuck media keys seems to be a timing problem with how QMK tries to pretend Chibios isn't async.
