Can anyone identify this keyboard?

Drag0nFly:
Thanks for replying @hasu. I performed quite a number of tests with the keyboard being detected as AT84 (working) and XT (not working) by changing the dip switch settings around.

btw.– This might be irrelevant, but I followed the Northgate Omnikey documentation (https://deskthority.net/wiki/File:Northgate_OmniKey_Users_Guide_Apr92.pdf), as that was the only other board I currently found with a similar DIP-switch.

However, this board appears to deviate slightly, since the board does not work in XT mode with DIP switch 1 set to “on”. Your adapter also works with the other low-numbered switches being set in the on position as well (although this should, if correct, change the protocol to ATT6300, Amiga, Tandy, etc). At least it worked with DIP switch 2 set to “on” and switch 3 (Tandy 1000SX and 1OOOTX) set to “on” as well (detects as AT84). It matches the documentation if all switches are set to “off” for AT-mode though – although only your adapter detects the board properly (same as the other modes). :)

Including the debug output below (again, based on multiple tests). The Soarer is consistently repeating keys, even though these are not being pressed when the TMK works fine in the same mode.

Which DIP switch setting does TMK works better with? All swites off?

The keyboard doesn't reply its keyboard ID. But TMK conveter seems to work well in AT84 mode, with some of DIP switch settings at least.
Is there any problem with TMK converter AT84 mode?

The keyboard seems to support XT protocol but both converters tend to miss its signal, signal timing may be unusual.
This part indicates that the keyboard works in XT protocol.

Drag0nFly:
Interesting observation about the XT-mode. My main concern was of course to try to identify the board in case there were some AT-specific models you added in order to provide support.

After some fiddling with the switches, I do get some output with the Soarer. It is not stable though, consistently freezing whenever the Pause-key – which is located next to backspace on this board – is pressed (your adapter toggles NumLock when it is pressed, in a variety of DIP-switch settings, and is stable/behaves consistently.)
So definitely no issues with your adapter when running the board in AT-mode (apart from some keys, such as PrintSrn, not correctly registering as such)

I had time to double-check and to perform some further tests, and the board is detected by the TMK adapter (as AT84) with DIP switch #2 set to on (AT&T 6300), as well as #3 (Tandy 1000SX) on and #1 and #3 on (Amiga 2000 & 2500). So I doubt the Northgate documentation applies for this board. But it was the only reference I had.

At some point in the tests hid_listen got “unknown id, report to TMK”–not sure if the output would help in any way.

I have not seen any of my boards report an id with the adapters though, which would uniquely identify them.

Not sure if this helps in any way, just including it for completeness. Seems to be quite non-trivial to identify this strange piece of hardware. ;)

According to Wikipedia Tandy 1000SX keyboard is not compatible to AT, it says "TRS-80 compatible; non-XT compatible". The DIP SW setting doesn't mean Tandy 1000SX mode if Wikipedia description is correct.
https://en.wikipedia.org/wiki/Tandy_1000#System_specifications
Also Amiga keyboard is not compatible to AT and the converter doesn't support it at all.
https://github.com/tkoecker/amigakb/blob/master/amigakb.ino

So your keyboard DIPSW doesn't match with Northgate manual. I guess DIPSW just changes scan code of some key, perhaps?
It would be useful for future reference to look into key by key and make scan codes diagrams for each DIPSW setting like this.

I think some keys were pressed radomly while the converter tried to read ID, in this case Tab(0D) and Esc(0E).
Agree. The keyobard doesn't seems to report any ID.

One key is "*", to the right of NumLock. This key produces "§" and "¶" with Shift. NumLock behaves correctly, both with your adapter and the Soarer.

Another key is PrintScrn (which outputs "*" when pressed)–

--- Code: ---r7C rF0 r7C r7C rF0 r7C r7C rF0 r7C

--- End code ---

The behaviour of PrintScrn is consistent, regardless of which DIP-settings are used. The "*" key (which is switched between "/" on newer boards) varies somewhat depending on the DIP settings. It does not however output "*" with any settings I've tried so far. Main testing is based on all switches set to “off”, btw., as I thought that would be the cleanest approach, until (if we ever) know what type of keyboard this is ;), and what the actual DIP settings do.

Scancodes when pressing the “Pause”-key with your adapter:

--- Code: ---r14 r77 wED rFA w02 rFA rF0 r77 rF0 r14 r14 r77 rF0 r77 wED rFA w00 rFA rF0 r14 r14 r77 wED rFA w02 rFA rF0 r77 rF0 r14 r14 r77 rF0 r77 wED rFA w00 rFA rF0 r14

--- End code ---

The Soarer is behaving so weirdly that it doesn't seem to be providing much useful output. When testing a number of times with it again, it crashes after the fourth or fifth NumLock press (which also toggles the LED). The Pause-key doesn't, unlike your adapter.

Output below is from two separate tests with the same DIP settings (switches 1 through 3 are on). On first attempt, the board is detected as AT/PS2, and when reconnecting it, it detects as XT.

The behaviour with the "s" printing occurs quite regularly when the Soarer crashes, and in the instance above it is after pressing the “Pause”-key.

The same test was performed with your adapter (DIP switches unchanged), and it behaves correctly (I pressed the NumLock and Pause-keys a number of times). Only difference is that the "*" key to the right of NumLock now outputs "(" and "/" outputs "-". So the DIP setting is apparently having an impact on those.

--- Quote from: Drag0nFly on Tue, 14 December 2021, 15:24:07 ---I had time to double-check and to perform some further tests, and the board is detected by the TMK adapter (as AT84) with DIP switch #2 set to on (AT&T 6300), as well as #3 (Tandy 1000SX) on and #1 and #3 on (Amiga 2000 & 2500). So I doubt the Northgate documentation applies for this board. But it was the only reference I had.

--- Quote from: hasu on Thu, 16 December 2021, 18:35:18 ---According to Wikipedia Tandy 1000SX keyboard is not compatible to AT, it says "TRS-80 compatible; non-XT compatible". The DIP SW setting doesn't mean Tandy 1000SX mode if Wikipedia description is correct.
https://en.wikipedia.org/wiki/Tandy_1000#System_specifications
Also Amiga keyboard is not compatible to AT and the converter doesn't support it at all.
https://github.com/tkoecker/amigakb/blob/master/amigakb.ino

So your keyboard DIPSW doesn't match with Northgate manual. I guess DIPSW just changes scan code of some key, perhaps?
It would be useful for future reference to look into key by key and make scan codes diagrams for each DIPSW setting like this.

Yes, I wasn't trying to suggest that your adapter should support Tandy 1000 (or Amiga 1000, for that matter). ;) I mentioned it as a reason the documentation for the NorthGate OmniKey did not apply to this keyboard, as the behaviour would then be quite different. (But it was the only doc for a keyboard with a similar 8-DIP switch)

--- Quote from: Drag0nFly on Tue, 14 December 2021, 15:24:07 ---At some point in the tests hid_listen got “unknown id, report to TMK”–not sure if the output would help in any way.

I have not seen any of my boards report an id with the adapters though, which would uniquely identify them.

--- End quote ---

--- Quote from: hasu on Thu, 16 December 2021, 18:35:18 ---I think some keys were pressed radomly while the converter tried to read ID, in this case Tab(0D) and Esc(0E).
Agree. The keyobard doesn't seems to report any ID.

--- End quote ---

That is probably the case. The reason is that the DIP-switch is at the bottom, and flipping the keyboard back and forth strains the cable connection. I've done that however now with the latest tests, so it should not be an issue.

(sorry for the late reply btw. – I've been restoring the keyboard, including the keyboard PCB cable)
