So I was able to get this far after I realized that the keyboard needed more than 5v (should have known!). It's still just those two keys but I haven't really had any time to tinker with it more. I did have a chance to try out LCtrl and it did indeed output 0x1d and 0x9d. When I first plug it in, th...

Only two keys on the board produce any sort of activity in hid_listen or Saleae logic: RShift and LCtrl

RShift (press)

RShift (release)

Three other jumpers are missing as well (J05, J06, J09). However, these look like they were intentionally left disconnected from the factory rather than cut after the fact (since they appear to have never been populated in the first place). Is it safe to assume that these probably are not the proble...

Some new developments in the case have unfolded in these past couple hours. I was reviewing the crime scene photos and found something that I had overlooked initially. It looks to me like one of the jumpers on the board had met an untimely fate and was either snipped or accidentally severed. I must ...

The NeXT case is the last unsolved mystery in my department. Our team here is great but frankly we don't have the manpower (nor the brainpower) to identify these suspects.

Upon to the scene, investigators found the victim unresponsive with no signs of life. The case immediately became suspicious due to the young age ...

My NeXT keyboard is sick

I got a really good deal on a "non-functional" NeXT keyboard. The previous owner had done some modifications that left the PCB in really poor shape. I played around with this board the other night and I kept getting excited because I thought I had found the (singular) problem causing the keyboard no...

There is a small probability that under the white 6-pin plastic connector the PCB has the pins marked with letters. Perhaps if you can unbend the pins just about 1mm and look between the connector and the PCB to see if there are any letters? (if you can do it without breaking something). No such lu...

Oh so not XT its firmware AT. that should help have you had any luck yet? If not, post some pic's of the back of the pcb to show traces. Still in the same pickle I'm afraid.

Pointer device for programmer

Hi guys, the other day I saw my coworkers rollermouse and immediately fell in love with the idea. I would really like a pointing device like this; where you don’t have to take your hands off the keyboard. One of the things that I do not like about the rollermouse is the size. My work keyboard is a R...

I'm surprised that Mitsumi miniature switches have made it to bottom ♯2. There are some people who genuinely like them, although there's some binding and it's nearly impossible to open the switch for lubrication. Is there any hope for these switches?

just try reading a logic high to start with just to make sure your setup is working. Yeah I think the sniffer I picked up may have been a good option a few years back when it was new and more supported but it doesn’t seem to play nicely with any of the software I tried (OLS and Pulseview). I found ...
