Got this board of eBay recently and was expecting Alps but Instead I got Cherries. The layout is identical to the Unitek (NTC) K-258 not the Dah Yang version layout. https://imgur.com/As9KBvg.jpg The back sticker is also not from this model as the FCC ID would indicate its for a KB-6251. However I h...

https://imgur.com/gA1WUGK.jpg Got this keyboard some months ago for cheap. After looking around and not being able to source the protocol for it I decided to USB convert it with an RP2040 and QMK. It uses linear Matsushita Spring Over membrane switches. The actuation occurs at ~80g with bottom out ...

I'm uploading the full User's Manual for the CH DT225 trackball with 8 pin dip switch setup on the bottom. Hope this helps someone in the future.

So, if I understand correctly , the barrel´s in the top part of the case do not have to modified to get this to work ? The wheelwriter key placement is the same as on the PCjr ? The only cut on the WW5's barrel plate was on the left hand side (on my picture the 10 barrels with no keys installed). I...

Looks awesome... except for the Windows logo, which seems out of place on that vintage looking board (but I guess I dislike seeing it on any keyboard) Thanks. I have been considering replacing the new Windows key with the old (Win95) logo to make it look more timely accurate. I use it often for mul...

Iam still curious about the components used. Is the upper part just the normal PCr top shell or is it custom 3 printed ? Also, which IBM (typewriter??) keyboard assembly did you use for the job ? The case is an original PCjr but it has been significantly modified (top and bottom). The only 3D print...

I made my own buckling springs small form factor keyboard (has the same key ...

I did some more measuring the PCB measures 205mm x 50mm (surface area). Here are some images of the PCB area with the unused pads/holes. I have backlit the PCB (put some light behind it) so the traces can be better seen. I also added these pictures to the original album linked on the main topic as w...

@clickykeyboards, the only details I have on the provenance of this board is I acquired it from ebay (2 weeks ago) and it was shipped from Coppell, Texas. The seller is an electronics recycler and had the board listed as an NMB keyboard, so I don't think he even knew what he had. I saw the markings ...

I have to be honest I got over excited about it. I agree with you as both the features you pointed out were my first indicators on thinking the coating was not original in the first place. My initial goal was to remove the coating completely, but seeing another board with similar looks made me think...

Took another look at the LED overlay (trying to figure out why it does not align properly) and comparing the images between yours and mine I noticed the recess for the LED overlay on my keyboard is not the same as yours. I looked at other images from the web and all the silver badge images I found s...

Thank you for this! It makes me happy knowing that the black covering is potentially original. The black finish and the missing piece in the bottom case will be professionally repaired in the future. I will once again look inside the case for that date stamp in case I missed it. The only pictures I ...

I just got this silver badge Model M (to pair up with my silver badge M122) but its lacking both the external sticker (birth certificate) and the internal stickers on the back plate.I know getting a definitive date will be next to impossible (unless IBM answers my inquiry with a date) but I want to ...
