Power no. Connecting ground to lets say metal case is good practice but not mandatory. It'll work fine without it.

Good job. But it's not finished yet :P
Now you need to rearrange the info above into table like this:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
r1 n9 -- NUMLK SCRLK PRTSC F12 F10 F9 F2 F3 ESC F1 F6 F7 F4 F5
r2 n/ n8 -- PAUSE PGUP BSP F11 a0 a2 a3 < a1 a7 F8 a4 a6
r3 n* n7 -- -- PGDN ' ´ O ...

Yep like this one.
156$ shipping though

Locally I've found Canon AP 800 with SMKs. So there's hope one with Alps will pop up eventually.

Ok I think I know what's going on here.
Why trace from pin 5 continues after "...." and "ctrl" key? It goes all the way under "R" and "4".
Does the "R" switch bridges pin 5 and pin 33 permanently? If that's the case they're the same.
Same configuration of pads is under "M" and that circle by the ...

Thanks!

hey, thanks for helping me out!
you're right, the u's lower leg should be pin 31 instead of 30! there are probably some more errors, i thought i'd iron them out as i go.



No problem. Always glad to help.
I've tried to make sense of the matrix with pins you provided. Row by row and I'm stuck on ...

Put a picture with corresponding pin numbers in the circle please.

Will try to simplify it for you :)

P.S. Check again if spacebar and U key are correct. They have the same values.


i find it extremely confusing to say the least! some pins are attached to ...

Considering vintage prices nowadays, every board with somewhat interesting switch is unobtanium.
Lets just say I'm glad I was able to start early enough to be able to try out as many switches as I did :lol:

The four in particular I probably never stop looking for are:
1. Alps SKFF board. Rare as ...

You have to figure out the matrix. 40 pin connector suggests it's bare bones keyboard without any ICs (but check anyway).

IBM 5576-001 Alps Plate Spring

Shipping might take some time, though. It's my "white whale" keyboard.

Great choice!
Shame those boards are so expensive and hard to buy in "western" market.

Couldn't resist and bought another one.
Might as well document it for the wiki, before taking it apart.

You can look into unicode support for QMK.

Oh wow. First hearing that forum was sold. Is there any summary of the AMA available to read?
Hope this site will not end up like freenode...

My keyboard of choice hasn't changed since I've stumbled upon marqs.
First typewriter conversion was from Olympia ES 100. Used daily from 09 Feb 2018 till 14 Dec 2019. So almost 2 years.
And this one took a beating since I did game on it a lot. To the point the E key crapped out at one point and ...

Analyzer bought.
So not for sale anymore.

Cheers

Hi there.

For sale keyboard module from Olympia ES 100 typewriter.
Partially restored. Switchplate and the rest of metal parts sanded and repainted.
Switches are Marquardt Butterfly's. Left untouched. I personally like them better lubed with ptfe (spray version), but in this case they're not so ...

Purdo comes from "pierdzieć" which means farting. Bol comes from "jabol" which is cheap wine sold in carton boxes.
It's a long story...

At this point it's going to be hard to pinpoint what's wrong with the board.
Still think that main IC got fried or at least some part of it. And testing ICs is beyond my capabilities and knowledge. I guess one way of checking it would be seeing what's the output in logic analyzer. But again I'm to ...

Ok so both ICs have proper voltage which is a good sign.
Did you connect the clock and data lines to check the keyboard (in either configuration)?
I presume the XT/AT switch is set properly to AT

Don't give up that easily :)
Search for the datasheet of the other IC (the one closest to cable) and figure out where the voltage goes.
If you have the datasheet of the main IC check the leg that's bent. What's it for?

After that connect the board properly and check voltages on both ICs. If there's ...

You can search for a data sheet of the closest IC. And check which leg is 5V. Then trace it back to the cable pin.
Then you'll have ground and voltage sorted out. With clock and data pins you can experiment without worrying of damaging anything.

Problem is, the damage could be already done. Wrongly ...

What's the source of replacement cable? Is it from another 5182?
First thing to check is that the keyboard is actually properly connected.
There's a picture on wiki of 5181, and the pinout goes like this: Clock, Data, Voltage, Ground.

I have something like this lying around.

Trouble is... no clue what it's worth :)
Caps are in good condition, except end key witch has ink dot on it ...

They're finicky when it comes to flashing. It's good you're familiar with linux though. Since it's way easier to do it on that os.
All necessary steps are here: https://deskthority.net/viewtopic.php?t=8448

I do it this way:
1. Pro Micro connected to check the device name in terminal.
2. Disconnect ...

This is fantastic! Great work! Sitting here looking over to my old Facit. Thinking i better keep it as a typewriter, but this would be fun to try out tho


Most likely it can be done non-invasively. Depends on the model of course. But if the keyboard module itself is bare bones (no integrated ...
