DCA IRMAkey/3270 issues #781

Closed SlaktarnP90 closed 4 days ago

SlaktarnP90 commented 1 week ago

Hi, I've just got my hands on a DCA IRMAkey/3270. I've ben told that it speaks XT and works with a IBM PC/XT (5160). I've wired up my Teensy with 1k Ohm pull upp resistors and connected the reset cable between Pin 3 on the socket and PB7 on the Teensy. I'm using the prebuilt .hex-file from GitHub [ibmpc_usb_atmega32u4.hex].

My 122-key terminal IBM Model F & G80-1500 with AT connector works with this setup. But when I connect my IRMAkey I manage to get one key to register and then I get a lot of errors, and after a while I can get another key to register followed by a lot of errors.

This is what I get from "Hid_Listen" when I press the "Q"-key. I wait for the errors to stop before pressing Q again. Sometimes it types the letter Q and sometimes not.

Any advice would be much apriciated! :)

Hi, The converter seems to miss the last bit of signals from keyboard(TIMEOUT error). Its signaling is very slow beyond what the conveter expects probably.

For furture reference can you capture signal form of your keyboard?

You can use Signal Capture Firmware to do that. Flash this prebuilt firmware to get text data of signals from keyboard.

https://github.com/tmk/tmk_keyboard/wiki/Signal-Capture-for-debug https://raw.githubusercontent.com/tmk/tmk_keyboard/refs/heads/signal_capture/converter/ibmpc_usb/binary/ibmpc_capture_atmega32u4.hex

To capture signals on startup and on pressing a key connect the keyboard with the converter first, plug the converter into a computer, wait for several seconds and press Q key. You should get some amount of text on hid_listen.

If you have a logic analyzer(or oscilloscope) please use it.

Thanks, Jun

Good morning,

Thanks for your help!

This is what I get. It outputs "0001" once per second. I waited for one row to fill upp with "0001" and then pressed Q but nothing happened. I waited a while before pressing again but nothing happened. At the end I tried spamming the Q-key, but still nothing. I did the same thing 4 times and it seemed unresponsive each time.

Thanks for the data. I could not find expected signal in that though. I may miss something.

Anyway, can you try attached firmware? I modified code to relax the timeout error(5ms to 10ms). timeout_10ms.zip

You're a wizard! It seems to be working fine now :)

Thanks for testing. I'll update github for the timeout error later. Before that I like to know about how long the keyboard signaling takes.

Can you try attached Signal Capture firmware again when you have time? I hope this works well this time.

Getting a ton of text while pressing Q-button atleast. I pressed the button with a few seconds between each press.

My firmware did not work again and seems to have unknown bug.

Soarer's logic analyzer should work with the XT keyboard then.

Download 'sctrace_v1.01_ATmega32U4.zip' from here and unzip it to get 'sctrace_v1.01_portD_ATmega32U4.hex'. And flash the hex file. https://deskthority.net/viewtopic.php?f=7&t=4567

Can you share its outputs on hid_listen?

Thank you for your patiance.

SlaktarnP90 commented 4 days ago

This is what I get when I pressed Q a bunch of times (8 times maybe), reconnected keyboard once.

Thanks a lot for your help! :)

I could see signal form of the keyboard finally. Thank you.

It takes about 5ms to send a scan code, this is 5 times slow comparing to original IBM XT keyboard. Interesting.

I updated code in github repo at commit https://github.com/tmk/tmk_keyboard/commit/3c7ca5b64bda3b7c98ce021c6e5f7d0a7a708877 .

You can download the fixed firmware from Keymap Editor now.
