As promised, here are the details on how to build a converter for this keyboard. I'm a novice when it comes to arduino/teensy programming but everything seems to work. It even supports NKRO! I'll try to make the instructions as clear as possible but please do feel free to ask a question. The keymap ...

Thanks for the info guys.

Here is the result of my experiments with photogrammetry https://skfb.ly/6AH6z

I have a very similar keyboard as well! I'll post some photos when I get home tonight. I am curious what switch is used on that keyboard you have. :D https://i.imgur.com/7GWacRD.jpg https://i.imgur.com/CYSQPdg.jpg https://i.imgur.com/i6r6Wku.jpg https://i.imgur.com/QzQspnz.jpg https://i.imgur.com/L...

Update: I was able to get it converted last night. If there's any interest, I can post the full details and source code here.

The link to the Wiki is right there at the beginning of the 1st post

My most sincere apologies

I have a very similar keyboard as well! I'll post some photos when I get home tonight. BTW this is the third time this week I've hears ADDS mentioned and I still have no idea what it is. Is it just a brand / type of terminal? I haven't checked to see what protocol (if any) my keyboard is. It has so ...

Here's what the patters are looking like. My keyboard doesn't have the bottom two rows of keys but you could probably figure them out easily through the process of elimination. Everything matched up to that memory map exactly with a couple of exceptions where a keypress didn't generate any output. I...

I confirmed with a quick and dirty arduino sketch that this is most likely how the keyboard reading works. My sketch pulls one of the signal pins low then reads each of the remaining 8 pins. If you press a key on the keyboard that's in the row corresponding to the signal pin that was pulled low, the...

I've been thinking about this a lot and I may finally have my head around it. I think it might help me cement that further if I write it down. Here's how I currently think the keyboard reading works: The computer (or microcontroller) activates some pattern of the first 4 pins to query a row. The IC ...

Bump

I thought this message was funny



And this question form my girlfriend killed me

Why does it look like pudding and mold???

I was talking to green-squid about the possibilities of building a keyboard from the guts of an IBM Wheelwriter. It would be ideal if someone had already designed a case that could be 3d printed or cut from layers of acrylic. But alas, it seems no one had done such a(n) (obscure) thing (yet). My nex...

What about us lot who already bought this switch, what are we to do? A purpose-built MX-stem shaving tool would be an ideal solution: You would push your MX switch into this device and it would come out shaved to known, safe, keycap-friendly dimensions. There are similar devices for other purposes:...

A lot of science of good information. But leaves me wondering; where is the good old fashion outrage?

Please help! I want to be a dignified keyboard conductor and have a mini virtual ballerina like this guy

Here's my lame attempt at mapping things out, in terms of what connects to what. https://i.imgur.com/rDQqL2y.jpg Certainly seems to match the explanation that I was reading on that one site What this means in practice is that the PC88 itself does the key reading. The keyboard connector has 13 pins (...

I've been mostly happy with my experiences using peroxide to whiten keyboards. But I do see a lot of posts where people have used retr0bright and the keyboard turns out ghost white. Is this really restoring the original color? Wodan's excellent post about using peroxide and heat really highlighted t...

Edit: There doesn't seem to be a release code which is interesting. Yeah, I think I'm going to have to make a compromise somewhere. I got a quick and dirty arduino sketch working but came to the conclusion that I have to choose between either: a) Make the initial keypress return a make and break au...

Eeek, I may be spreading some misinformation. Edited post accordingly. In any case, I know my issue has to do (in some way) to this since it is working now. Curious about what the right way to hook this up is. So I guess what I've learned is that circuit ground is different from earth ground. This p...

I'm trying to write a simple arduino sketch but I'm not sure how to approach it. What I'd like to detect is when a key is pressed vs when a key is held. Here's the behavior of the keyboard: When you press a key on the keyboard, the keyboard sends 0x00 followed by the ascii value of the character. If...

So I came into another TeleVideo keyboard and spent some timetoday trying to learn more about the signalling. I'll do my best to summarize what I've learned so far. ASCII So far it seems like the keyboard outputs ASCII codes for each exact character (e.g. 'a' vs 'A'). The signalling is 9600 baud, 8 ...

Total noob mistake. I was using a Soarer's converter that didn't have the din sleeve wired to Gnd.

Working on cleaning up the rest of the board. I decided that I'd like to use it for a week or two then ultrasonic the switches (and fix up any keymap things). That way I can compare what cleaning the switches really did.

I'm working on remapping a keyboard that is outputting some mixed up key presses. For the most part this is very straight forward! I'm just wondering how the syntax would be in my config file if I need to remap a key that outputs multiple keypresses. Is this possible to remap? For instance, when I p...

Something similar was happening to me and it turned out to be a voltage problem. Do you have a multimeter? If so, check the voltage on the board to make sure it's adequately high. Mine was around 4.2V when I experienced the problem. Sometimes it can be a simple fix like making sure ground is properl...
