All soldered in. Now I gotta figure out this power issue. The guy I spoke to over reddit didn't mention this to adapt but I'll try to contact him again.

Quick tip on soldering: the chisel tip is fine (it's what I use), it's more on method. For joining the wires to pins with solder, I'd tin the wire lead, tin the pin lead then heat them together to reflow the joints into one. Same process one would use for something like soldering leads on LEDs. Whe...

Don't clip the the other jumpers and you should only solder the new ones on. Oh so just leave the JA jumps? For my own needs; what is filling these links supposed to enable? From my understanding it enables the AT protocol on the board. Heres some photos, sorry for iffy camera quality. There's a 78...

Oh so just leave the JA jumps? I'll make sure not to. Any tips on getting the wires to stay put while soldering? Just pray?

So just clip the JA jumpers and solder those two JP jumpers together?

USB is not directly compatible with AT protocol. PS/2 is compatible with AT and there are plenty of PS/2 to USB converters on the market though (and again, only if it has XT/AT switching on the mainboard since it appears that these used two protocols depending on manufacturing date). So, how would ...

Blaise170 wrote: Ooh I misunderstood the wiki. Looks like if you desolder the RJ-11 cable and replace it with a DIN-5 or PS/2 cable that it should work as long as it has AT switching on the board.
So just stripping a USB and soldering it to the respective pinouy should work?

Hot plugging PS/2 isn't the best idea. The Mini-DIN connector for PS/2 and the larger DIN one for the AT are standardised. What's inside connecting the cable to the keyboard's PCB isn't. You might get "standard" 0.1 inch pitch pin connectors which are fairly easy to deal with, or something else alt...

Hence, why I scrap them for the wire and materials. No sense trying to resell it (worthless) or use it myself (fire hazard). Speaking of, do you know of a place I could get a ps/2 cable that could work too replace that rj11? Or if it's possible? I found a thread that showed the pinout, I'll try to ...

first off do you definitely know that it will not work with a pc in some way? if it was made after about 1980 then there is a good chance there are already commercial or community made converters that already exist.

I (not so recently) purchased a PCB off of Aliexpress, as it supported ALPS and had a 40% layout that I wanted to try out for mobile typing. I got my switches, (Alps SKCM Cream Dampened), and have some keycaps. But I have since hit a brick wall. I need to get a case for this thing, and although I do...

This would be sort of a primer to the one I discussed waaaay far back about SKCC Alps, as I want to familiarize myself with soldering after a long while of not practicing. Anywho, as I was testing my o...
