Bang on the money. Don't feel like swapping out the foam yet, that feels like an all day project, but I cleaned up the PCB of the crumbs and it's a lot better now. Thank you

No, actually spamming it repeatedly tends to prevent it. That sticking theory would actually perfectly explain what is going on.

I know the answer is probably take it apart and check those switches but I'm desperately hoping there's something quick I can do without resorting to that. I'm a lazy bastard

Recently picked up a 5251, she's from December of 1979 and remarkably clean. I converted it to USB and have been using it for work, but occasionally a few of the switches don't activate when I press them. Like, they physically don't flip the pad, I don't hear the click even when fully depressed. Aft...

Thanks for the warning. I've been wanting to add them to the collection, now I won't be super trigger happy about it!

Damn, sitting on the tactile bump is how I type quickly... Well, guess it'll live in it's new box for quite a while

I've been cleaning my keyboard pile and pulled out a board with clicky black NMB Space Invaders. Tried using it, but the switches all consistently activate on the top of the tactile bump. It's the only board with them I have, so I wanted to see if any other SI diehards have experienced this.

Apologies, it said to turn here for assistance. I managed to figure it out with a bit of help from my dad

I recently received my USB beamspring controller and can't seem to get it working. The IBM capsense USB util doesn't recognise there being a controller connected. I bought the controller new from Joe at Model F Labs. I appreciate the help!

I recently spent 1000 on a pretty good condition 5251 and I'd say go for it. Beamsprings are getting more desirable and more expensive as a result. If you're on the fence, try to get a feel of them at a keyboard meet, but as long as that thing isn't rusted to crap you should have little issue sellin...

Anyone know what we’re looking at here? Never seen anything like them before.

Man I've seen houses plug into the electric grid with less chumky connectors! Those are gorgeous

I think most peripherals can be better or worse whereas keyboards are different from each other. Mice, for example, have more accurate ways to sense movement. Keyboards aren't getting better or worse, they're changing. Some people prefer the feel of beam or buckling springs, others like the sound of...

I wouldn't be surprised if the case has a lot to do with it. I've compared the sound from my IIgs keyboard to an AEK and the ping is definitely less noticeable in the roomier AEK chassis. Every switch has their quirks, in my opinion that's what makes this hobby so great. I'm typing on a Model F77 ri...

Alright I think the outdated VIA files are the issue. I'll try using the QMK layout generator here http://35.164.28.200:5000/#/xwhatsit/brand_new_model_f/f77/LAYOUT_all to create my desired layout Another option, if you're feeling adventurous, is to try Vial instead , which I've already built a cop...

Hi, I tried to update the firmware to the VIA version. I followed the guide to the best of my ability but it's not outputting anything despite being picked up by VIA. What do? Was the keyboard working before you flashed VIA? ...oh, no. Just noticed something. In Ellipse's firmware ZIP archive, only...

Alright, I don't know what's going on but it always seems to deteriorate after a certain mount of time. I've wanted to get a desoldering gun for a while now, so maybe I'll get one soon and take the plate off to see what's going on. Thanks for the help guys.

I could see the whole micro being quite a characterful keyboard for a modern machine! I'm not sure honestly. I do like how the computer looks but it's too big for my desk (especially because I'd want a 104 key nearby with a 60% layout). Part of me wants to recreate Chyros's Project A and build a wo...

I would have said blue Alps before but I just got my Apple IIc in the mail and it has almost perfect Amber Alps and I definitely prefer them. Now to get a converter and figure out where to route the cable.

Wow that thing looks gorgeous! Linears aren't my personal cup of tea but I hope you enjoy it

I mean, I could destroy it for you. Just send it to me and you won't have to worry anymore! I have... uhhh... FIREWORKS!! Yes fireworks I'll blow it up with fireworks I definitely won't add it to my collection

It definitely was a lot better before. It works well when first plugged in, so I tested it, thought it was good, and closed it back up. It deteriorated over a little gaming session so I opened it back up and fixed up the first job so now I just have to wait and see if it'll get worse again. Edit: 24...

Resoldered the input pins on S17 and the problem keys started working a lot better. For a while the tab and 1 keys were linked to each other but that issue seems to have resolved itself after some careful prodding! In fact, this message was typed on the keyboard. Thank you all for your help.

Alright, so it is continuous but not everywhere, which might explain the issues. I'll try reflowing it tomorrow and update as soon as I do. Thank you for all your help so far!

That's exactly what we needed. The problem column splits off after the ~ switch (S17), and all the switches after it in that column are not working, so if the ~ key is working correctly the problem will be either the solder connections on the right pins on that switch, the internal leaf which jumpe...

Share some good pics of the PCB and I'll have a go at working out the matrix: specifically the broken part. A little hobby within a hobby of mine . :roll: https://imgur.com/a/ywWNteC Here is an Imgur link with the full PCB, a closeup of the problematic section and a duplicate with marks next to the...

And as soon as I say that and shut the case it starts acting up again.

I imagine those specific keys would share the same column on the switch matrix, check before 1 If you mean the ~ key, that one does work. Actually, I took it apart to test the continuity to see if it was something obvious and they seem to have gotten much better. If you have any advice for a more l...

I recently bought an RT101+ on eBay for a good price, but the tab, 1, q, a, and z keys don't actuate reliably. Sometimes they don't sometimes they do (especially if I mash them), and sometimes they chatter. Does anyone know how to fix this? I know very little about circuit diagrams but if someone ha...
