Olympia ES 100 keyboard conversion for PC use
Hi there. I've decided to document my venture into converting Olympia electric typewriter board for PC use. Specificaly the one with Marquardt Butterfly switches, since I think these are really underrated, not talked about much. And very undeservedly so, they're excelent switches.
1.1 Format
This is mainly build log not a guide. I'm far to newbie at this stuff to make an actual guide. But I will try to make it as universal and easy to "follow" and share as much info as posssible, for people actually interested in doing similar thing.
1.2 Boards
Currently I own 3 boards with these switches. One ES 101 and two variants of ES 100. They're all in different shape as can be seen from the picture. For the project I'm going to use ES 100 (bottom one) as main board, and ES 101 (top left) as a donnor for parts.
1.2.1 Known models that have butterfly switches
If you're searching for a board like this, the easiest way to spot one is the little orbit logo. Olympia Electric Standard line of typewrites made in early to mid 80s. Model numbers: ES 100, ES 101, ES 105 and probably ES 110 (not confirmed yet).
1.2.2 Maintenance tips
1. The easiest way to pull the caps off is prying them from bottom up with tweezers, needle-nose pliers... what have you. Since the mount is angled, I found this method reliable easy and safe. Of course you can use keypuller instead but be careful not to pull the caps straight up, because it can snap the slider mount off. They're not really robust when mishandled. It's a ~36 year old hardware...
2. Enter key is heavily stabilized. In order to pull it off, firstly pull those little round metal thingies from the rod. Then remove the rod and the entire keycap will come of.
3. Dissasembling the switches for cleaning is really easy and can be done without desoldering the switch. Reasembling can be a little finicky, but once you get the hang of it, it's piece of cake.
1.3 Goals
1.3.1 Vintage look
Most people making boards these days go for "modern" look. Which means small form factor, "naked" keys etc. I don't like it, it makes them look samey, and without character in my opinion. So the goal here is to make the opposite. We're going for the vintage look. Lots of presence, lots of "wasted" empty space and so on. Had many ideas (some very bizaare tbh) how the board supposed to look, but as it's my first project, so I need to constraim myself a little here. Not only because not realy sure what can be realistically pulled of with my skill set or lack thereof, but also because the choice of materials I'm going to use. Specificaly kydex sheets, that are not available bigger than in A3 format (40x30 cm). Which complicate things a little. Lets say it's a test run for future projects...
1.3.2 Made mostly from what's in the basement
Aside from parts that absolutely need to be bought, like connectors atmega boards and kydex. I will try to use stuff that's lying in my basement. Find it satysfying to repurpose old useless things lying around into something new. Like piece of wood from old closet, steel plate God knows where from or even old electronic devices. The obvious downside be, lots of try and error in the process and no pretty design set in stone from the start. The finished board may look way different
than what's in my head now.
Connecting to the PC
The process should be pretty straight forward, since keyboards from olympia have pretty modular design. No controller on board no wierd old protocols to deal with. Just a simple PCB with switchplate, mounted keys in one tidy package.
2.1 Keyboard matrix
2.1.1 Bottom of the PCB
In the top right corner there's our pinout. Numbered (left to right) 1 to 18. All swtiches are numbered too, except the 3 button module on the left. So...
PCB --> reffers to switch number printed on the PCB
PIN 1 --> will be columns of our matrix (first leg of a given switch)
PIN 2 --> will be rows (second leg of a given switch)
As you probably noticed 4 keys on this board are double action. That's why they have 4 legs instead of 2. Vertcial contacts --> primary action of the swtich. Horizontal contacts --> secondary action of the
swtich.
Unnumbered 3 switch module will be used for layers. So let's call it layer2, layer3 respectively. Layer1 is default so we ignore it.
2.1.2 Let's find out what actual keys corespond to PCB numbers
Might as well check the pinout while we're at it...
2.1.3 Finished matrix in more readable form
CAPSLOCK, lSHIFT and rSHIFT - same pins same key. All secondary action ones are connected to same pins too, together with big R key. Cariage return is big thing in typewriter word it seems 
PIN 14 is unused, so there is an option to add more switches, or leds for example. 10/12 key is a latching switch.
68 keys in total, which makes the board fit the 60% size category I guess...
2.2 Layout
Since we know how everything is conneted internally, it's time to think about the layout. But I'm to lazy to do a fancy picture. So brief description...
3 way lathing module on the right side will be the layers (1 - default , 2 - function, 3 - not used atm).
10/12 lathing switch on the right side is currently unused, but there's something planned for it.
Top row on the right side will be left and right. Bottom will be up and down. Those are double action so hard press will trigger CTRL+Up and CTRL+Down. Might be usefull to assign something to it in I3. Same with space and backspace. Hard press will trigger CTRL+space, CTRL+backspace.
T+ and T- are pageup and pagedown buttons.
ESC top left corner, Win key below it (never going to use it but what the hell) and the lCTRL = "big R". That's the first column.
Capslock and shift are on the same pins so we're gonna use the lShift key globally.
First layer is just a function layer.
Top row with numbers becomes F1-F12, WSAD and HJKL - arrow keys etc.
The rest is pretty much standard.
2.3 The controller
2.3.1 Test run
To avoid the unexpected surprises, it's good practice to do a test run before soldering the controller in. I've picked spacebar as a test button, which on the matrix is PIN 15 and PIN 8. Manualy connected first wire (simple loop) to PD2 pin on Pro Micro. And the second one to GND.
Flashed the Pro Micro with TMK keyboard\onekey with two small edits in onekey.c In matrix_init and matrix_scan functions changed default pin from PB0 to PD2. Connected keyboard to pc, pressed spacebar few times
and saw "a" popping up in terminal. Cool everything works as expected.
2.3.2 Soldering
This part is self explanatory. Rows to the left, columns to the right for simplicity. Wired mine like this.
Cannot count so the PIN5 landed at the bottom...
2.3.3 Reset switch
I've decided to add the reset switch, at the place that can be easily accessed. It's good thing to have, for fine tuning firmware in the future. Dummy switch under cariage return <CR> ("big R") seems like a perfect spot. With board fully assembled I can acces it simply by puling out the cap and dummy switch cover.
Bit of hot glue and the switch is in place. Two wires go to RST and GND pin on the Pro Micro board.
2.3.4 Arrrgh
Usually don't like to do this, but the Pro Micro board has no mounting holes. And I'm to stupid to think of any clever way to attach this thing. So hot glue it is... bleh... seriously use the hot glue as last resort...
Yeah I left out waaay to much wire lenght wise. Cable management ain't pretty. But it works, and that's the most important thing right? Also worth noting, standard micro USB fits, but the connection is very tight. The plug sits on a diode. So swapped the cable for one with slimmer plug instead. Not in the picture but you get the idea.
2.4 Firmware
Used gh60 as base, and edited it accordingly.
2.4.1 matrix.c
2.4.2 keymap_common.h
2.4.3 keymap_olympia_E100.c
2.5 Cleanup
Well it's finally time to clean this thing up. Was able to ged rid of most of the gunk with soap, and some alcohol (not that one in the glass
). The switchplate is quite rusty though. Sanding and painting is on the TODO list. This wil have to wait till spring though. [board_cleaned] [assembled_after_cleaning] Really don't know what those white spots at the top cover are. Scrubbing does not get rid of it. This part needs a paint job too...

};Well it's finally time to clean this thing up. Was able to ged rid of most of the gunk with soap, and some alcohol (not that one in the glass
). The switchplate is quite rusty though. Sanding and painting is on the TODO list. This wil have to wait till spring though. [board_cleaned] [assembled_after_cleaning] Really don't know what those white spots at the top cover are. Scrubbing does not get rid of it. This part needs a paint job too...TBC
