I've been filling my quarantine boredom with a lot of keyboard projects. With a couple exceptions, all of these have been fully run through, ultrasonic cleaned, sous-vide retrobrighted, lubed, plates repainted, internally USB converted, etc.

In roughly chronological order:

Apple M0110A
Spoiler:
I got a NOS-ish one with Mitsumi switches but was pretty disappointed in them. Robbed the guts from an SKCC model and got a PCB design from a guy on GH.

TI Silent 700

I had to buy a 56k modem to make it work.

Cherry POS
Spoiler:
Case was pretty scuffed so I tried out some hammer-tone paint.

CM Storm QFR
Spoiler:
Had this board since the Ripster days. Switched it out to some 1988 blacks from a WY60 missing half it's caps.

Unfortunately didn't send release codes so I did a full brain replacement.

Since I had some browns now laying around. Caps are doubleshot ABS and came off a random rubber-dome.

There's a few more in the works and a bunch that I don't have good photos of the process but you get the idea.

I could imagine how much effort and time you put into this, good job, man.

I love that you actually made new PCBs for totally forgotten boards like the 3M Whisperwriter and the GEAC 8340 but no one ever made new PCBs for fullsize Alps boards like the SGI Granite. There are only like 15 GEACs out there. It's great.

Now this is some high quality work! keep up the great restorations

BlindAssassin111 did some replacement PCBs for the AT101W; not sure if it would fit other Bigfoot boards.

I suspect we're approaching a PCB singularity-- we're probably 70% of the way to "accurately render the board in keyboard-layout-editor, click three buttons, and you'll get a file you can sned to JLCPCB" for a lot of non-complex PCB designs.

What caps did you use in the ALPS64?

They're front print KBParadise ALPS V60 Vintage ABS.

Not the nicest caps (pretty thin) but they do the job. I'm having a hard time finding the Tai Hao set I want in stock anywhere.

Love the Bluetooth M0110. Really have to do that with mine someday.

Also really like the sneaky socket upgrade on the ADB board.

If turn-key PCBs become a thing, my pre-PS/2 (no Bigfoot!) SGI Granite could really use one. The keyboard's in excellent shape, and has real character, but the protocol is undeciphered and I think it even needs more voltage than USB anyway. A real outlier.

I've been keeping an eye out for one of the grey speckled SGIs but they seem pretty hard to find.

I jotted down my from scratch PCB design process if anyone who has one wants to give it a shot. It should be simpler than what's in the guide since alps are a known footprint. viewtopic.php?f=7&t=25613

Cool! Nice to see it done. Something tells me if I went solo on this model, I'd have MOQ-1 PCBs on my hands for years to come. :P

Salvaged a couple more boards from the recycler.

Unicomp M
Spoiler:
This had been through a couple rain storms and unfortunately there was a bit of rot on the membrane.
Image
Image
Image
Image
Image
Protype
Spoiler:
Also rained on before I found it but luckily there was no corrosion. It speaks a non-standard serial that didn't want to play nice with hardware UART so I went with a controller swap. The IC was the same footprint as a Teensy++ 2.0 so it turned out pretty tidy.

Also needed a normal-ish layout quieter board for the office.

Filco
Spoiler:
Came with knockoff Alps that were pretty bindy and didn't have the nicest tactility. Threw in some Matias quiet clicks that get the job done.
