It is a drop-in replacement for Mk1 of Analog Four, Analog Heat, Analog Keys & Analog Rytm to replace original lower contrast LCD.
I have currently 4 units left in this batch.
It is a yellow/green/white/blue on black look.
So if you want the OLED look of Mk2 and have Mk1, then this could be a cheaper alternative than buying mk2, though some desoldering + soldering is expected from you/a friend/a local technician.
Asking 120€ for it + shipping. Located in Europe, Latvia.
Contact me here (PM) or via email ( order @ xrd.lv). (Currently no purchase via ebay or paypal available, but will send you invoice directly.)

Unfortunately I do not know anything about machinedrum process.
Generally this is a two part job:
(1) disassembly to get to the display (and assembly afterwards);
(2) display module replacement (desoldering old + soldering new).
For the first part I can’t say much.
Only have experience with opening Analog Keys, and for that the disassembly to get to the motherboard/display board was not hard, if You know cables, that need to be disconnected. Cannot tell anything about A4.
If You have/buy a desoldering tool (e.g., Engineer SS-02 or a clone), You do not have to touch A4’s motherboard at all. So You would not be risking damage to the motherboard at all (at least in the soldering part).
Can’t find a more reasonable video right now, but for the purpose of seeing responsiveness, here is a short clip from development days before designing a board for the display.
Phenomenal work, bravo! I have poor eyesight and have always struggled to see the Mk1 screens, would love to have one of these in an A4 or Rytm. I’m sure they’ll sell like hot-cakes.
Though take the colors/brightness of these images with a grain of salt…
They’re not quite what You see with naked eyes and photos are not well done either to be representable of what You get.
The blue/turquoise one with my eyes seems to have significantly different color.
Probably not. Some panel units might be, some might not. These specific size/interface units are manufactured by a few manufacturers.
I ordered these units from China which were readily available (to me as a private individual) and then on arrival I just tested each display myself.
Currently I only have one green display left.
And two more empty boards without OLED panels…
So yesterday I ordered 1x blue/turquoise, 2x green, 2x yellow OLED panels.
Probably will take a week or two to arrive.
The white one does not seem as bright & nice as the yellow one to my eyes, so I did not bother ordering white one.
I can order the white OLED panel, it just takes time to arrive.
Cannot directly help much with installation, unless You happen to be in Latvia with Your devices.
What use case are You thinking of, regarding screen sharing with PC?
It can, theoretically.
Though that would be a significant amount of work to do that sensibly & make it usable SW-wise (both on the OLED board & PC side).
HW-wise - You would need to somehow manoeuvre/route a data cable out of enclosure.
Before there even was an OLED, there was a try at what You asked about.
