Re: IBM model F XT not working suddenly

Thank you, orihalcon! It's just ingenius! I've never ever dreamed of such a simple solution ;) I'll try my plan first just because it's much cheaper (and I've already ordered the programmed controller). But if it doesn't work, I'll definitely follow your recommendation! I've got just one question. W...

Re: IBM model F XT not working suddenly

Thank you very much for suggestions! I have already found a guy who dumped the ROM seven years ago. He just sent me the binary.

Re: IBM model F XT not working suddenly

It turned out that Intel 8048 is a factory flashed chip. Good news: there is Intel 8748, the same chip, but rewritable. Also, as far as I've found, there is no write protection exists in this chip family. So, the plan is: To desolder and check the capacitors. To find the firmware of 8048 dumped by s...

Re: IBM model F XT not working suddenly

Hey ;) No intermittent typing whatsoever. It just died completely. What do you mean by disassembling? To part the plate from PCB, put off keycaps and pull all flippers out? How come it could be of any help? I already put off the back lid, unplugged the internal cable connector, and plugged it back i...

Re: IBM model F XT not working suddenly

Thank you very much.
So, the biggest chip is Intel 8048 controller. Is it flashable? Or if it's a culprit, and I change it, will it work right away?

Re: IBM model F XT not working suddenly

Hello guys, I've got the same issue. All of a sudden, my F XT refused to work. (Soarer's converter on a Pro Micro clone.) Right before the failure it started to type itself some garbage, I've plugged the USB off, and then on again. And enjoyed the silence. I've flashed another Pro Micro and tried it...

Have you tried to isolate the D6 pin from the rest of the scheme and take a look how everything will go in that case? Because I was told that using the LED pin could lead to instablility in the work of Teensy.

OK, I'm going to use the TMK firmware, and will take further investigation about the potential level need to drive LEDs. But, looking at the Ergodox, which utilizes the TMK code too, the LEDs' cathodes have to be connected to the ground, and anodes — to the corresponding Teensy pins (through resisto...

Scarpia, thanks for your detailed answer!

So, if I've got it right, I'm only need to wire GND pins for LEDs, and leave the '+5V' pins floating (or vice versa)?

Asking for the Teensy PCB wiring help

Hello friends, I'm trying to create the DIY-keyboard PCB. I've decided to drive my keyboard by Teensy 2.0++. Summary it will be 26 lines: 19 for the matrix (10 rows, 9 columns) and 7 for LEDs. So, the question is: what to do with the power pins of the Teensy ("+5v", "GND")? I've took a look at a ple...

That Soviet keyboard has been discussed a few times and the general consensus is that they are Fujitsu Reed switches. Oh I did not know that. But we don't really know about the switches right? I forgot that I actually happened upon the manufacturer awhile back. It's a Pravetz. It was reviewed here....

Hello,

I've faced the same trouble: each of 3 buttons from the same column produced a character sequences when pressed.

I've taken a look at the PCB back side and found one tiny unexpected bridge between neighboring LED and diode cathodes. Cleaning out that bridge solved this problem.
