The Alps Plate Spring G80-1000
Posted: 24 Nov 2017, 00:51
So just completed my latest project! The APS G80-1000! Sounds weird right? Cherry and Alps together?!
But it works. This project aims to re-case the IBM P70, as its case frankly sucks. Flimsy and flat, made as a side panel for the IBM P70. I chose to use the G80-1000 since its a pcb mount case like the P70; I figured it would be easiest to get working. However, it wasn't a simple drop-in fit. I had to do some reworking of the original PCB:
First I had to make some cuts. The bottom piece with the metal bar, the detachable connector area and the top two corner areas which are just holes to save weight all had to go. The case only needed to be slightly modded; cut two pegs that stick out of the top case so the PCB is able to sit flat against it.
Next was the LED problem. The original ones don't line up with the new case so I had to desolder the old ones and put new ones in so I could line them up with the long legs. I broke a few LED pads and had to handwire them as well. Finally I had to wire it up with a cable. I used a OG Dell AT101 cable for this and it works/looks great. Additionally, I used OG Dell AT101 keycaps to replace the meh thin P70 caps.
How it looked in the end:
Final assembly:
I am super pleased with the result - it looks factory!!! I'm really surprised no one has tried this before. APS is a fantastic switch, and the P70 provides a usable layout (unlike JIS ) but with a few flaws (thin caps, crappy case) and now I have fixed these issues and I love it!
