Hey guys, it's been a while. I've done the in-chassis converter, but the problem is still quite present. I have identified the offending 'repeating' keys, but I have other problems- such as the F keys spewing randoms commands, one most notably changed my entire monitor to red.

Regarding the ...

Thanks for explaining what the teethed nut-connector was, and power cycling fixed the problem. The problem wasn't with the firmware, rather an obscure windows thing that I still have no idea how to toggle.

So, I reconnected my keyboard to my PC again, and the problem is still persisting, but I ...

I got some time to remove the incorrect resistor, and that hasn't been able to fix anything.

I haven't deticiated an hour yet to trying an in-chasiss conversion, which I'll be doing very soon.

I have temporarily fixed the shielding (?) connector with some wire.

I'm not well versed in ...

Damn, ok- I'll keep you updated.

After some wrangling with my teensy, I haven't gotten to soldering it inside, but before I took it apart, I noticed that the teensy may be the problem. I am not completely sure if it's an official one, or an imitation, but it's probably the latter. Small bumps to the controller seem to cause it to ...

That seems reasonable, I'll probably keep them, thanks!

Quick question, when I'm doing an in-chasiss conversion, should I keep the pull-up resistors? Since it's so close, I think I should omit them, right? Or should I keep them incase the signal is still rocky?

That's good to know, I really don't want to take the board apart for another year or so. I'll be doing the conversion once I figure out the pins, and have some time to sink into soldering, still recovering from a burn from trying to desolder old wires from it.

First, because I'm not someone who really fooled around with electronics, I really appreciate kmnov2017's comment about grounding. Because ...

I also have a Model F XT that does a similar thing: if you press one of about 11 keys, the keyboard will register multiple random keystrokes. In my case ...

Do you have all the keycaps installed on the keyboard or are you testing this with the keycaps removed?

Also, test by directly wiring up the teensy to the original controller, it seems the original cable is damaged from one of the pics you've posted.


I'm testing with the keycaps installed ...

Spewing of text can happen for the following reasons

1. The chassis is not grounded properly.
2. The converter you built has a short.
3. The original controller on the keyboard is faulty.

To check the chassis grounding, use a loose piece of cable, connect one end to the shiny back plate (you ...

Hi peeps, sorry to post another IBM F XT problem post, but after scouring the forums on both GT and here, as well as reading though the Soarer's converter documents, I can't seem to fix my problem.

Currently, I have built a teensy 2.0 Soarer's converter, first without the ...
