Hey any news of the GB launch? Can't wait!

fingers crossed!

Any news? Itching to join the GB

Awesome! Any chance we can start placing orders for a GB?

Big update! The PCBs are in and the look beautiful :) Due to choosing the ENIG and gold chamfered finger options, the PCB looks beautiful in yellow! Without further ado, here are the photos:

I've ...

just a quick update -- all spots are filled but happy to take backup spots still. The order has been placed and once the PCBs are in, I'll take photos and try it out on my 3277

With emdude's support, I'll be running the 66-key split spacebar GB posted here: group-buys-f50/ibm-3277-66-key-split-sp ... 17149.html

4 spots available and FCFS

So thanks to @emdude 's tremendous efforts in designing a xwhatsit controller compatible PCB, the IBM 3277 keyboards can now be used with your home PC! You can check out his work here: https://deskthority.net/workshop-f7/xwhatsit-cs-compatible-ibm-3277-pcb-t16867-60.html

Here is the photo of the 78 ...

@orihalcon : heard that you may run a split space 66 GB and I'm happy to join. Sent you some PMs earlier on this. If you're busy, I'm happy to host a mini-GB as well and get it up a running for some interested parties

@emdude : a big thank you for making this happen! really love how there is a growing community of people that can use their old beamsprings :)

@orihalcon : like hansichen mentioned, will you do a GB on the PCB? I PM'd you regarding a new order along with the controller and solenoid. Would be great ...

that's wonderful news and thanks for putting this together in such a short time! so basically, I can PM Orihalcon if I need to order the split space and 66 key versions since they ready to be fabricated?

Ok! Can't wait to see how the 78 key PCBs turn out

just tested the split spacebar one and it's perfect! everything is aligned and good to go put me down for 2 split spacebars and one 66 key please. Keep up the great work

awesome work! Just had a busy week but will check my measurements w/ photos in the next 2 days. Can't wait the see the 66 key split space version out soon too

hey there, how's the project progressing? now that I receive my X60 board, I'd love to have this PCB in and join the GB

@ipreferpie, I will need more time to figure out a matrix for your split-spacebar 3277. I was originally thinking of reproducing the original matrix, but the way the column traces are routed make that a no-go, I think. I will keep you updated on that.

no worries and you really got the plans out ...

Ground fills have been added, so I think everything has been drawn now. I'll attempt importing the DXF into Diptrace and hopefully produce a working Gerber I can use to order PCBs with.

emdude and Sangdrax: good eye you guys have. I assumed that the traces would be the same as the other 3277s but after having it mapped out, I can see that I can be done. Would replacing the controller with an xwhatsit one be the controller replacement solution? But I do agree in that I'd prefer to ...

EDIT: @ipreferpie, thanks for the photos. I may just make your PCB a separate design. I'm hoping that the other mini 3277s share the same pad placement. Since I don't think the full-sized PCB will be going to anyone with that particular layout, this iteration of the PCB will probably be the final ...

definitely want to make it usable and crossing my fingers that emdude is successful!

No, the photos with your industrial ruler look fine. Please check the PCB with a printout of the PDF when you can though. It seems that the distance between the two pads differ by at least a millimeter. Based on my PCB, the center-to-center distance should be 35mm.

Depending on whether the other ...

So thanks to this wonderful community and to mrr19121970, I was able to land a beautiful 3277 with a unique split spacebar layout. The following is a photo documentation of the disassembly process. I was pleasantly surprised at the great condition and am happy that this is my first proper beamspring ...

@ipreferpie, here's a 1:1 scale PDF of the new PCB. I think we've hit a snag; it appears that the distance between the Enter key pad and the rightmost pad of the set of four is smaller than on the full-sized 3277.

This might be a problem, I'll need to see more pictures/measurements of another 66 ...

thanks all for the kind words! and Slom, wonderful banner! Happy to have it being used here. Also, should I cross post in the photos section for more visibility?

Here is my photo documentation on the 3277 split space board: workshop-f7/ibm-3277-beamspring-split-s ... 16907.html. Enjoy!

emdude: Yeah I was totally surprised but the amount of extra pads there. I wonder what other permutations of the bottom row were released on the 3277. As for the spacing, it does look like the are spaced apart by 1u increments there. And it looks like the 0 key is actuated on the second pad from the ...

Finally got some time from work to clean up my split space 3277. I took some photos and hope to comment on the documentation on a separate post. Here are some relevant photos that may help in the PCB design. Please excuse that fact that I do not have any calipers for fine measurements, but please ...

ok still good news! let me get back to you on the documentation soon to help out. Much appreciated on your efforts

Sure! I would have to modify the matrix to accommodate the additional key so the sooner you can get the photos and measurements, the better!

Will do! I will aim for this weekend to make it happen if everything this week is smooth at work. Thanks for including it :)

Just read your edit LOL. I ...
