Space Invaders can be pretty great keyboards.

I have the ADDS version of this board. It feels very nice indeed. I hope eventually to figure out how to convert it to USB.

Had a look at the PCB? Could be possible to swap out the old controller and hook up a Teensy. That is the case with my NMB, although I don't need to as it's already AT.

That reminds me, I still need to take those pictures…

Do you have more details on what to look for and what the procedure would be for hooking up a Teensy? I am still quite new at this.

The key concept is the keyboard matrix. Switches are almost always laid out in an X-Y grid. If you can get direct access to that, by removing the original controller, then things are looking good for hooking up your own controller instead.

A replacement controller, like a Teensy running TMK or Soarer's Controller firmware, just needs full access to the matrix to work. First you figure out the logic behind the keyboard's hardware mapping (where the switches are connected to the matrix, whose paths are almost always curled around to make a bit of a puzzle). You can do this by a good photo or two (PCBs are often two sided) but you're best off with an electric continuity tester. Second, you hook up every column and every row to its own pin on the Teensy. And then third you setup your logic in software, telling the Teensy's firmware which pin means what row, and what the matrix looks like. For a peek of that, look at my custom 60%'s config. Then, fingers crossed, it all works. It actually did for me on this very keyboard! One step at a time will get you there…

For instance, here's a picture HAL posted just earlier of the inside of his NIB Model M:

Image

Those two connections are straight off the membranes. One is the columns of the matrix, and the other is the rows. You can pull them out quite easily, no tools required. IBM was generally pretty good with designing its keyboards with separate controllers. You can swap one Model M's controller with an other, and typically it will work just fine.

But you could choose to hook up a Teensy, or some other programmable hardware, to the matrix yourself. This is what I plan to do to make a Bluetooth SSK. But it would work today with a Teensy and Soarer's Controller firmware. An experiment I mean to try first.

Keyboards with PCBs, like my NMB, are a bit trickier. If the original controller is on a daughter board, then you are home and dry! But if it's integrated on the same PCB as the switches, things don't look good. Even if you hook up a Teensy (or whatever else, for say Bluetooth…) to the appropriate rows and columns of the matrix, the old controller will very likely mess things up with its phantom connections to the same matrix. You really want to make a clean break.

All of this only really applies to simple "Ohmic" switches like space invaders, MX, Alps, and Model M buckling spring. Capsense is another matter, and I'm pleased indeed to let Xwhatsit summon the beam springs!

@Muirium: Many thanks! This is exactly the sort of careful explanation I was seeking.

Still looking forward to seeing the illustrated manual for constructing a converter box with multi-way selector switch!

Received both my space invader keyboards yesterday: one with white, linear switches, the other with black, clicky switches. Both boards are in great condition, although the board with clicky switches is in need of a good cleaning following its time in storage. Nothing a little oxy can't fix. It is missing a single keycap though; so I'll need to see if I can't scrounge up a replacement keycap online somewhere.

The board with white switches is immaculate though -- full keycapset, and so clean that I thought elecplus had accidentally shipped me a NIB board.

Either way, both boards are a total steal at 25$ + S&H in my opinion, complete keycapsets or otherwise. I'd definitely recommend them to anyone who hasn't yet had the chance to try these funny little switches out for themselves. (Although be sure that you're willing to build a converter for them, one of my boards had an AT-style connector, while the other uses an 6P6C. Both will need converters in order to be used on a modern-day system.)

Hi, great to see you have much more NCR Model 4950 keyboard. First to see this model have the (Linear)White two big eyes! Are all switches have white?(Because as I knew NMB Hi-tek switch keyboard have didferent color on it.)
I found the same model have the black one.

Could I have a chance to see the switch under "Lock" key and space bar on your keyboard?

Cindy, any chances of getting the keycaps only ? i'm mainly interested in the numpad ones.

Terrycherry, there are locking space invaders switches ?

Seems like a big waste to salvage these nice, fairly rare keyboards for just their keycaps.

It could have latching lock if the keyboard was made from 1985.12 to 1987.04.
If made from 1987.04 after, it could have these 7variants inside "Lock" key:
(Linear)White with LED.png

(Linear)Magenta with LED_1.png

(Linear)White one eye.png

(Linear)White two laugh eyes_1.png

IMG_2017.jpg
Grey with LED

(Linear)White new two eyes(without click arm)
(Linear)Black new two eyes(without click arm)

As I have no time to edit my NMB Hi-Tek photo(I took all details I had), these picture can not look very clearly.

Yes, if non-deatils to collect is waste money.
As my situation, I brought 11keyboards with NMB Hi-tek switch and much more parts(keycaps and some switches) for 33 variants of this switch, the amount is USD323 only!
p.s: near 12variants still collecting...

If it helps i have an ADDS board (but mine is ansi bitches YEH! )t and a simple converter worked (its XT like for the protocol at least on my ADDS board , i suspect they would keep the protocol the same.

Yes, I need help to make the ADDS to PC converter for my NMB Hi-tek keyboard.
Did you mean the ADDS keyboard not use the XT protocol and could be the individual protocol?

Here's my keyboard which used the MMJ(DECconnect) port. (I guessed)

You can slowly see the design evolving in to the ansi one i have :) you know the one that you don't have :P unless your name is xmit :D.

The protocol is quite simple. If you could get me an image of the internal connector it should have at least the folowing

GND
CLK
DATA
VCC
RESET

you can just connect GND CLK DATA and VCC directly to a soarer programmed pro micro ( not sure of the pins will have to check) and let RESET float , this should make it work. My reasoning for thinking it is XT( or something close enough to work with the converter) is the scancode set and the reset line.

Note this is for the ADDS terminal one i have , but the AT&T one looks like a re branded ADDS to me.

Thanks to guide me=]
But I have 6pins. The connector was cut, I could give you the original 6pin socket only.

I tried to connect with another AT cable, the main IC just got heat....

AT&T brought ADDS in 90s, it should work.

My place can buy the Teensy 2.0 and 3.1 or arduino pro micro 5v/16M Leonardo. Which one is better?

chances are both the black wires are Ground , red 5v the others will have clock and data lines .

you got a multimeter with frequency or even better a scope ?

Oh, I haven't the multimeter. I should buy one with the Teensy next week.

And I found the same keyboard brand ADDS logo keyboard(early than the NCR model 4950 keyboard)
