Magnavox Videowriter keyboard rebuilt from parts. I received the parts in addition to the Alps SKCM Brown switches that went into my AEK alps64 build.
I used Alps SKCM Blue switches that were originally in terrible condition that I bought on eBay – to give you an idea, here's what they looked like when I received them:
Each switch component was given 25 minutes in the ultrasonic cleaner (other than the switchplates). Miraculously, this restored them to a pretty decent state. However, the switchplates did not work, so I ended up swapping them with a mix of short switchplates from Alps SKCM Cream Damped switches and working first-gen Alps switchplates.
On to the Videowriter! The case and caps were in fantastic condition, so I couldn't pass up the chance to rebuild this nice compact board.
The SKCL Compact switches and caps were not provided, so the ones that ended up in the keyboard are from a Sharp PA-1000.
The PCB was not in such a good shape, and also needed a controller replacement to work over USB - for this I used a Teensy++ running QMK. This started out fairly neat, and you can see the neat aspects of this replacement from the front of the PCB.
I then fixed a few traces between switches that were broken due to lifted pads. However, things didn't work right off the bat. Keys in row 6 (D, F, G, H, J, K, L, ;) were also registering presses in row 7 (X, C, V, B, N, M etc). During troubleshooting, I lifted a fair few pads around the controller, so these had to be rewired by hand. Additionally, I couldn't find the short between rows 6 and 7 with any amount of tracing, so I ended up disconnecting row 6 from the PCB and handwiring it:
Finally, the stabilizers, and especially the 9U(!) spacebar were impressively rattly, so I lubricated the stabilizers with Threebond silicone grease. This didn't impact the hollow sound from the spacebar though, so I filled the inside of the keycap with neoprene to dampen that somewhat.
Everything works now and it's a delightful little board.
