#3 - Multiple Rubber Dome Keyboards
Accidentally picked/bought these. They're not for me but I'm sure someone out there will like them!

Hi Guys,
Decided to make a place to post things I'm not sure what to do with and would like to offload. Let me know if you're interested in anything or have questions. Everything here is free, just cover shipping.

#1 - Blank ____ keycaps (~70)
I'm not sure what mount these are. I got them with a ...

Glad you've stuck around

(Also, I didn't know the final outcome would be a bin-file, I thought it was a hex-file since that's what the Teensy loader-software asks for..)

Soarer's converter is the ice cream, the config is the toppings.

See this very scientific diagram which I have put together to explain the differences ...

Hey snufflecat,
The basic workflow for the config goes like this:

Write your config using a text editor (e.g. my file would be called "snacksthecat.sc")
Use Soarer's command line tool scas to assemble the config (e.g. "scas.exe snacksthecat.sc snacksthecat.bin)
Use Soarer's command line tool ...

Here's my first crack at a converter. Just 80 lines of code! This AVR stuff is pretty cool.

const int KBACK = 0;
const int KBRDY = 5;
const int KBDATA = 1;

const long keyMap[103] = { KEY_F8, KEY_F1, KEY_F2, KEY_F3, KEY_F4, KEY_F5, KEY_F6, KEY_F7, 0, KEY_F9, KEY_F10,
KEY_ESC, KEY_TILDE, KEY_1 ...

Making some progress! I wrote a small sketch that does the following:

Continuously poll the keyboard by sending ACK messages in response to RDY queries.
Attach interrupt to RDY line on falling edge (treating this as a clock)
Read in the 9bit message coming in over DATA
First 7 bits tell the ...

How? I mean, I certainly agree that it is stuff. Just not Apple stuff that I recognise.

It's this one. I thought it was an actual Apple marketed product but maybe it was just compatible with their machine (?).

One thing that comes to mind would be one of these funky keypad assemblies:

I see them show up on ebay sometimes. I bought one from there about a year ago. Big blue saw was running a deal at the time so I got a big thick ...

What ever happened to zool?

That guy helped me work through a lot of different troubleshooting episodes and got me into learning more about microcontrollers.

Great work!!! Registered just to reply :p, I just got my hand on one of these, I am wondering what would it take to make an RJ14 to USB adapter for this?

Thanks!

It would actually be pretty simple to create a converter for this board but there would be significant limitations. The biggest ...

I think someone is selling replacement F&F pads on eBay, but I figure it's more fun to do it yourself.

Thanks for this. I opted to buy a set since I'm a bit swamped at the moment.

I made a tiny bit of progress on conversion (at least I think I did).

I set up a saleae analyzer for "simple ...

I actually do think the foam is goobered. I took the PCB off the switch/plate assembly and checked it out. It looks to me like they're all deteriorated and (possibly?) not making contact with the pads.

Then I wrote a little arduino sketch to send the ACK signals ...

According to what I'm reading online, it's possible that the foam in the switches as deteriorated and maybe none of the switches work? I guess this is something I should look into before going any further trying to get a peep out of it.

Update: Yeah, that new text is more like it. Again, I’m just guessing, but it sounds to me like you could poll the keyboard over and over quite easily, using a single pulse low-hi-low from KBACK. The 250 ms figure means the keyboard will announce the last key code every quarter of a second until it ...

Wow it's explained even better deeper into the techref:



Gives me a few things to try but I still think I'm in over my head a bit.

Thanks for the input, Mu. I'm definitely up to the challenge (or at least to dip my toes in the water).

I think I've got the pinout right. Vcc and Gnd were easy enough to trace. For the others, I'm relying on my interpretation of the maintenance schematic

Hi Guys,
I got a Victor 9000 keyboard that I get to play around with.

First, some photos of the board:

The Beamspring Briefcase

You’ve got my attention!

Audiences around the country can't stop talking about the riveting fall blockbuster, "Man Removes Keycaps from Eight Keyboards".

Now, Snacky Cat Films™ is proud to present the sequel you've been waiting for, "Man Puts Keycaps back onto Eight Keyboards".

Does the "BackTab ...

Unfortunately I'm short two of these style left shift keys that some of the boards take (the ones that do not have a backtab key). The switch mounts on the left side and it has a little guide rod on the right side that pokes down into a faux switch.

I reached out ...

Building up a small collection of the different color SI switches!

Five more of these beauties are available. Pictures to come later today but PM me if you're interested.

One bad scary movie later and I've removed all the caps.

If you've ever wanted to watch someone pop the keycaps off of 8 boards in one sitting; boy, do I have the movie for you!

This weekend is going to be dedicated to cleaning my filthy apartment and cleaning up 8 of these Pawns that have already been converted. I was thinking that all of the soldering was out of the way but I realized a couple of these keyboards have broken switches that need to be replaced from a ...

This is the layout I've been using. The pink keys are my own modifications. I did my best to go with the original intent of the key when I could. And when I couldn't, I tried to use something that made sense ergonomically.

Also, I have about 40-50 of these little boxes with tiny USB mini cables. If anyone wants them (all of them or just a few), send me a PM. I cant think of any use for them and it seems wasteful to toss them.

No real update yet. I'll hopefully have time to knock out 8 of the pawns this weekend since they have the same matrix and the teensy++ 2.0 drop in works nicely on these.

I just wanted to share a small technique I've picked up. I've been doing a lot of desoldering for this project and it's always a ...

If you have the inclination to get into it, I would suggest trying to make an external converter for this thing. I don't think anyone has figured out how to do that yet and it would be great to see one of these used with a modern computer.

That was actually my initial plan when I picked up my ...

I thought I'd seen someone in the interesting finds thread say that they were looking to buy the keyboard without the switches but then when I went back and read it, he was actually just looking for the carrying case for the whole machine
