IBM 4704 Keyboard Converter
« on: Wed, 12 February 2014, 18:38:39 »
Acknowledgement
Without generous big help from 002 this would never happened. He helped me to obtain this keyboard, gave me one as a gift or donation more precisely. Thank you 002!

And without Soarer's help I would have given up this work at early stage of reverse eng.

Disclaimer
This converter is mainly for 'proof of concept' purpose. It may or not work for your everyday use. (I'm very confident of this converter now. It works well enough. :D)
Won't offer step by step tutorial and support. But feel free to tinker it yourself. Your improvements and new discoveries are welcomed, let me know. Enjoy!

Post your question here, DON'T PM/EMAIL ME unless you really need.

IBM 4704 Keyboard Protocol
ibm4704.txt:
See the latest version at:
https://github.com/tmk/tmk_keyboard/blob/master/converter/ibm4704_usb/ibm4704.txt


NOTE
Audible Clicker
The converter doesn't control the clicker/speaker.
- With Alps models the converter cannot control clicker at all but you can change sound volume with dial on bottom.
- With capacitive models the converter can control/use the clicker theoretically but doesn't support. You will hear beep while startup after plugin but no clicker at all when typing.

Waiting for first post to be filled in.  When it is if this point isn't covered, here's what I must ask:

Did you get this working with the stock controller?

Awesome! I have another teensy-size project box. I think instead of a panel mount dsub connector, I'll just chop up a serial cable and use that.

Hasu succeeded where I failed; his reverse engineering was masterful :D

I've been playing with the protocol as well, following hasu's notes above. The FD command just seems to make the keyboard emit a short beep, presumably so the terminal can emit a BEL code.

The Chinese/Japanese IBMs with vintage Alps use the same protocol, and the same command sequence (FC, 80 .. F6, FF) enables release codes for all keys. Scan codes output are different to the KS for most keys. On powering up, both the 6113442 and the 6112884 send A6 as an ident code.

Thank you, Soarer. I'll fix my document later.


And...
For those who are interested, my converter has some limitations:
1. Keyboard(6019284) has only *3-byte* key buffer.
2. Keyboard has same scancode on both Alt key. You can't use different scancodes on those.
3. My converter is naively *polling* at not so fast speed.
Due to 1. and 3. you probably will see missing keys and transposing keys at very fast typing.(my wpm is less than 60 and I don't have a problem) To solve or mitigate this problem we can use *interrupt* method instead of polling.

Replacing controller board doesn't have these limitations. It is still very intriguig option to squeeze every last drop of its power out of this keyboard.

I can also confirm that the 50-key outputs A2 as its ID. (I didn't see it output it on startup, only after sending a reset command (FA) to the keyboard, but that might be because I'm sending commands before it has time to output it).

IDs so far...
A2 = 50-key
A3 = 62-key
A4 = 77-key (unconfirmed)
?? = 107-key
A6 = the vintage Alps CN/JP

The 107-key surely uses this protocol, but we don't know if it uses the same ROM image. It has no ID pads on the PCB -
http://kishy.dyndns.org/?attachment_id=1045 - if it does use the same ROM then the ID would A0, but A5 fits the sequence better!

Not that I would recommend it, but cutting the track to the ID pads ought to make the keyboard output raw matrix position codes rather than scan codes, which would then distinguish between the left and right alt keys.

Got my teensy yesterday and now the keyboard is alive. Thanks guys! but the missing scancode for the right alt really is a big loss for me, as I use it very frequently.

But it is definitely a good interim solution until the complete replacement controllers are here.

Wow great work hasu!

Do you think this would work with my 3178?  It is like the top one here:



Here's a picture of the guts:



I just a couple Teensy 3.1 boards and was going to see if I could drive the matrix myself using the touch pins ... I'm probably not smart enough to pull it off so this looks great!

bcg, I don't know much about IBM keyboard models, though, I guess it uses diffrent protocol than 4704. It doesn't seem it is part of 4704 banking system.

prdlm2009, README didn't help you? You won't be able to find more detailed instructions in tmk repository. Maybe you need Googling of AVR and gcc toolchain, I guess.

EDIT: Note that tmk_firmware has also README file in root directory in addition to in each project directories. You need to read both README files.

Recently added keymaps for 77-key and 107-key. Thanks orihalcon.

And protocol handling bug was fixed today, it seems like this solves key stuck and drop problem.

With your firmware does it matter what chipset the keyboard is running? I cracked open the 6112884 an my board is running a TI SN74159N. I was under the impression they had the intel 8048 or did I just misread other posts.

No, keyboard controller itself does not matter but keyboard protocol matters.

SN74159N is just one of 74 series IC - demuxer, not controller :D
http://www.ti.com/lit/ds/sdls059/sdls059.pdf

I think you can find other IC package of controller on the board, probably 8048 or compatibles.

With the Blanks on the 6112884 do you have any recommendations on the best way to go about starting to map those keys? IE. what did you use to find the hex for the original layout. My second question as I have never used a teensy how do you load your code on to that d**n thing.  :D

You can use 6020218 107-key keymap for start and I guess it works also on 6112884 probably. If it does not work or has wrong keymap you will have to change keymap file. I can tell the detail of investigation/debug in that case.

At first you need converter hardware, its wiring is explained in README on github.
https://github.com/tmk/tmk_keyboard/tree/master/converter/ibm4704_usb

Next compile firmware to get binary hex file and load the hex to Teensy.
https://github.com/tmk/tmk_keyboard/blob/master/doc/build.md

As for loading hex to you can find PJRC instruction on their site.

Going to resurrect this thread since I'm having issues with my own converter for a 6112883 keyboard.

I was able to make and load the hex file for the plain layout onto a Teensy.  When I run hid_listen, all the keys respond to presses (there are one or two blanks on the far right cluster that are giving errors, but that's it)...but the keyboard won't actually function in Windows.  No Start Menu search results, no Notepad results, etc...but hid_listen works.

Am I missing some sort of step in this process?

The plain keymap is for capacitive switch models, your Alps switch model probably use different scancodes and you need to define keymap for the keyboard.

First, look into scan codes of all keys and make table like below. You'll see scan code on hid_listen when pressing or releasing a key.

So, late response, but I have yet another question, Hasu:

I've been looking through your codes for the keymaps, and I'm wondering if I just overlooked it:  Is there a code for turning off a keyboard's solenoid/beeper?  (The IBM 6112883 has a speaker in it, and while it's cool to have on to show it off, I don't think I could stand to have it on all the time.  It's either this, or I'll need to desolder the blasted thing.)

I did notice "Volume up/down/mute" codes, but those are for media controls, not the keyboard itself, correct?

EDIT:  I can't read the Japanese characters on the keyboard, either, so if there was originally a designated key for doing this, I have no idea.  :x

At least my 6019284 stops beep after sending FF at end of initialization. The code is located at enable_break,
() in  matrix.c

Mine has no solenoid. If your keyboard has solenoid I think it has a command. But I don't know that.

Thread Res!

I have an IBM 4704 (6112884) version.
I've played around with the firmware, and I've put it on the teensy several times.
I will also dump the break codes below. I get scan codes in hid_listen on keypress for all keys except one of the macro keys.
I'm lost as to how to get this working as a keyboard. Any help from anyone would be super appreciated!

The scan code table will be below as well. They are in the order of how the keyboard is laid out.

Break Codes:
------------------------------------------------
Waiting for new device:...

hmm, all of 'enable break' commands are not accepted with your keyboard.
For example, this displays that the keyboard responds erroer FD(out of bound) when send the command for scan code '00'.
Code: [Select]
s00:rFD


Those Alps switch models probably work a little differently than cpacitive switch models. My code has depended largely on my 6019284 behaviour and it does not work your keyboard well.

I found Soarer mentioned earlier that your 6112884 accepts 'enable break' commands. You probably have to send 'FC' to start sending the commands.
Quote
The Chinese/Japanese IBMs with vintage Alps use the same protocol, and the same command sequence (FC, 80 .. F6, FF) enables release codes for all keys. Scan codes output are different to the KS for most keys. On powering up, both the 6113442 and the 6112884 send A6 as an ident code.



Try this patch to add 'FC' on top of commands. And this will fix the one bad key(7B).

The scan codes that are actually mapped to keys function properly. Now all I have left is to make a keymap for the 102 layout!!!
Thanks so much Hasu, couldn't have done it without you. I'll also post or PM you a good default 102-key keymap if you'd like to add it to the configs.

Great. Thanks for the report back.

I confirmed that fix works also on my keybaord and pushed the fix to github now.

Alright, I've run into a few more issues. I've got a keymap, but the keys laid out in keymap_plain (for example) don't line up with the scan code values. For example, here's my keycode config in keymap_common.h

Code: [Select]
#define KEYMAP( \
    K00, K0F, K01, K02, K03, K04, K05, K06, K07, K08, K09, K0A, K0B, K0C, K0D, K0E,   K44, K45, K46,   K43, K41, K42, K4A, \
    K10, K11, K12, K13, K14, K15, K16, K17, K18, K19, K1A, K1B, K1C, K1D,      K1E,   K54, K55, K56,   K50, K51, K52, K5A, \
    K20, K21, K22, K23, K24, K25, K26, K27, K28, K29, K2A, K2B, K2C, K2D,      K2E,   K64, K65, K66,   K60, K61, K62, K6B, \
    K30, K32, K33, K34, K35, K36, K37, K38, K39, K3A, K3B, K3C, K3D,           K3E,   K74, K75, K76,   K70, K71, K72, K7B, \
    K31, K47, KBF,                 K40,               K4F, K48,                K2F,   K77, K67, K57,   K73, K63, K53, K4E  \
) { \
    { KC_##K00, KC_##K0F, KC_##K01, KC_##K02, KC_##K03, KC_##K04, KC_##K05, KC_##K06, KC_##K07, KC_##K08, KC_##K09, KC_##K0A, KC_##K0B, KC_##K0C, KC_##K0D, KC_##K0E, KC_##K44, KC_##K45, KC_##K46, KC_##K43, KC_##K41, KC_##K42, KC_##K4A }, \
    { KC_##K10, KC_##K11, KC_##K12, KC_##K13, KC_##K14, KC_##K15, KC_##K16, KC_##K17, KC_##K18, KC_##K19, KC_##K1A, KC_##K1B, KC_##K1C, KC_##K1D, KC_##K1E, KC_##K54, KC_##K55, KC_##K56, KC_##K50, KC_##K51, KC_##K52, KC_##K5A }, \
    { KC_##K20, KC_##K21, KC_##K22, KC_##K23, KC_##K24, KC_##K25, KC_##K26, KC_##K27, KC_##K28, KC_##K29, KC_##K2A, KC_##K2B, KC_##K2C, KC_##K2D, KC_##K2E, KC_##K64, KC_##K65, KC_##K66, KC_##K60, KC_##K61, KC_##K62, KC_##K6B }, \
    { KC_##K30, KC_##K32, KC_##K33, KC_##K34, KC_##K35, KC_##K36, KC_##K37, KC_##K38, KC_##K39, KC_##K3A, KC_##K3B, KC_##K3C, KC_##K3D, KC_##K3E, KC_##K74, KC_##K75, KC_##K76, KC_##K70, KC_##K71, KC_##K72, KC_##K7B }, \
    { KC_##K31, KC_##K47, KC_##KBF,                                                          KC_##K40,               KC_##K4F, KC_##K48,                KC_##K2F,   KC_##K77, KC_##K67, KC_##K57,   KC_##K73, KC_##K63, KC_##K53, KC_##K4E }  \

I have both an 8x16 matrix table and that one right there that matches exactly the keys on the keyboard.

What's weird is that even after I changed the keys in keymap_plain to match that layout, they don't match up. For example, where it should be the "1" key, it's printing the character "u". and where the character should be "2" it's printing "1".

I found that if I changed the key where it would normally say "u" to be "1" (reversing the process), the "1" key does indeed display "1", but that's not what I should be doing to fix this.

Any ideas guys? Any help is appreciated!!

You have to define keymap macro for your Alps keyboard like definition for 107-key. Note that the latter part of the definition should be an array 16x8(keymap[16][8]) containing sequence of scan codes from KC_##K00 to 7F basically, but use KC_NO for scan codes not used in the frist part. The first part of your definition seems to be correct at a glance.

Alright! It's completely done! Thanks Hasu!

I'll post more stuff later, I actually made a script to make the scan code grid for you, but I have a few little things I want to fix with it first.

Alright! I want to go a bit farther in this project.
I started thinking about making the keyboard wireless, and I saw that you actually had some bluefruit support in the firmware.

I want to pick up a bluefruit so that I can do the whole bluetooth thing (I wish I could just use RF, but beggars can't be choosers)

Does any significant code need to be modified to get the firmware working with a bluefruit? Or can I just wire it in and go? I have to power it of course.

I saw this article: https://learn.adafruit.com/convert-your-model-m-keyboard-to-bluetooth-with-bluefruit-ez-key-hid/use-it

where someone converted an IBM Model M using your firmware with an arduino micro (gross) and a bluefruit for the bluetooth part, but I didn't quite grock what he changed in the code for that part. Since I already have the working code for the 6112884 is it just plug and play?

Thanks for the help, and I'll keep everyone updated as I receive advice / make changes!

P.S. I also have the RF module from an old membrane keyboard, I don't see how I could get that to work with the current setup though, it has an 8x15 matrix (and the pins for it) on the PCB, but I just wanted to transmit the data through it....oh well..

Including protocol/bluefruit.mk instead of lufa.mk should work basically. Not so tedious job.
But I don't thave the module and haven't maintained it, I'm not sure it works with the latest code base.

BTW, I added keymap of Alps 102-key and update repository!

Oh awesome! Thanks for the mention! It means a lot. I'll pick up a bluefruit soon and play around with it, I'll post the results here of course.

I never expected there to be actual community for old keyboards lmao

Quick thread necromancy... anyone modified the code to send the correct (0xFD?) code to the keyboard controller to make the buzzer / bleeper inside buzz/bleep after every keypress?

Do you recall which keyboard / converter you compiled with?

I think Soarer did that and confirmed FD command works on his capacitive model keyboard.

Vintage Alps models works differently, they emit beep themselves without FD command from converter.

I guess I'm looking for the correct location to insert the send function call.

My first attempt was in the initialization section and it beeped a few times.  Last attempt I pot it in the debug util function and it didn't work at all.

I'll work it out eventually...

Do forgive me if this is a stupid question; I've been looking over the documentation for a while now but I'm still trying to wrap my head around it; I received my Hasu's Converter today; it's lovely and I'm typing on my 6112884 right now; I'm thrilled to have spherical keycaps like the old VT100 I first used at age 4!  What I'm after now is the ability to re-map the keys.  I know this is something that is possible with this unit but I'm on Windows and I'm no programmer, so I'm afraid a lot of the information is lost on me.  I see that there is a keymap file on github which corresponds to the functions of the keys, and I gather that I'm supposed to be able to make my own version of this and somehow upload it to the microcontroller's RAM, but I simply don't know how to go about doing that.  If someone could be so kind to spell it out for someone who hasn't touched a Unix command prompt for ten years, I'd be quite appreciative. 

I feel that I should say that I'm exceptionally pleased with the converter; the only thing like a complaint I could raise is that the DE9 plug on it has the wrong type of locking screws for the mating connector on the keyboard, but this is easily overcome and shouldn't be anything like a major issue as I intend to put the whole board into a small box to keep it from damage and dust (does it get hot in operation?  Should I put vent holes in the box?)  Also, what is the purpose of the small button on the board?

Read these document if you didn't yet.
https://github.com/tmk/tmk_keyboard/blob/master/tmk_core/doc/build.md
https://github.com/tmk/tmk_keyboard/blob/master/tmk_core/doc/keymap.md

Procedure of remap looks like the below. I'm not usually on Windows, so I may pass by something improtant, though.

1. First, you need to install Toolchain to compile firmware(.hex) file from source code and Programmer app(FLIP) to download firmware into MCU(ATMeaga32u2) on converter.
https://github.com/tmk/tmk_keyboard/blob/master/tmk_core/doc/build.md#1-install-tools

2. Then open Cygwin terminal and compile firmware. You will see firmware file 'ibm4704_usb.hex'.
Quote
$ cd tmk_keyboard/converter/ibm4704_usb
$ make -f Makefile.tmk_rev2 clean
$ make -f Makefile.tmk_rev2

3. Open FLIP to program MCU(ATMega32u2) with the firmware.
Push small button on converter before run FLIP. The button on converter is program button, you have to push it when program it.

I dont think the MCU needs ventilation.

Alright, I think I know what I've got to do; I've got all the tools and I've edited the keymap file; I'll post it at the end and hopefully someone with more experience at this than I can tell me if I've stuffed up before I go flashing ROMs or whatever it is that happens when the microcontroller is programmed.  Do I need to hold down the button while it programs or do I just press it once to put it into programming mode? If a single press, do I need to press again to return to normal operation?  Again, sorry if these are stupid questions, but in spite of spending a lifetime around computers, this is the first time I've done something like this.

Anyway, this is what keymap_alps102key.c looks like in the specified directory for me right now:

Yes, you need to push a button just once before programming, pressing the button turns MCU into programming mode. No, you don't need to push the button to return normal mode, it usually works as a keyboard after programming but if not just replug.

'MACRO' doesn't work as you defined, except for it it looks good to me.
Unfortunately no document of 'MACRO' action is located around, you have to learn someone's keymaps or from trial and error.
This is my macro definition in my keymap, for example.
https://github.com/tmk/tmk_keyboard/blob/master/keyboard/hhkb/keymap_hasu.c#L233

You cannot break your hardware with programming mess up keymap, try it at ease!

EDIT:
If you mess up your converter program with this firmware with default keymap to recover it.

Reminds me of an old joke about a computer salesman who tells his worrisome client that "Nothing he can enter at the console can harm the system in any way".  The client, re-assured, buys the system.  A few weeks later, the salesman gets a call from the client, saying that he has indeed entered something at the console that damaged the system.  "what was it?"  the salesman asks.  "A can of coke..."
