Aside from my DZ 60 I'm just waiting on parts for my second build to come in. It took me a while to finally decide on the config for my first build since I was trying to go for portability, functional layout as well as some other aesthetic choices I insisted on, like split spacebar and arrows. The next build will use a Dawn 60 by Xelus and I plan to make a custom sandwich case using only clear acrylic to maximize RGB. Now that I learned how to solder I just want to keep making more. Those all sound like solid workhorse boards, did you have to add USB support for the IBM models? What are your plans for the dz60 as far as case, switches, keycaps?
Nice. Split spacebars seem interesting. If I didn't think it would ruin my muscle memory for other more conventional boards, I would love to try it out. those acrylic sandwhich cases are cool. I have one for a Raspberry Pi. I think I would probably try to play around with the opacity and/or color of the layers if I were to be playing with LEDs myself. I imagine completely clear is going to glow nicely.
Soldering can be therapeutic, can't it? Also, maybe, somewhat fulfilling, to know that you've assembled something yourself. Not just slapping something together, but with just a little more permanence.
SKCM blue Alps are all I worry about at work. They're sensitive to dust/debri. I keep a towel over my Alps boards though when not in use. The rest are pretty much bulletproof. Kailh's box switches are IP57 rated against dust and water, and on the TG3 "cop keyboard" I modified the silicone mat that protects the plate and switches to prevent it from adding rubbery tactility to the switches themselves by cutting off the tops of the domes, since the switches themselves are relatively well sealed. Capacitive buckling spring is so simple that those boards will basically just work, forever.
The IBM F AT will only require an active converter if you do not have a ps/2 port on your computer. I use them through ps/2 if I can, with a 5-pin DIN to ps/2 adapter. Most desktops still have it. The protocol is the same, so that's all that's necessary. The F107 already had a replacement controller with a USB interface. I do believe that active conversion to USB is required for the IBM 4704 family. The new production F62s and F77s come from the factory with the same controller. Otherwise, I do have a few Soarer's converters I have put together, and a TMK converter, either of which work with most retro keyboards from the mid 80s on, including the F XT.
I ordered a walnut case, something I have always wanted on a keyboard (I'm a fan of old wood and iron, etc). I also ordered a brass plate. I ordered a mini usb version of the PCB since it was the last USB standard I found acceptably durable and user-friendly, couldn't find it with hot swap sockets so I ordered those separately. It will be my first, and maybe only, hot swap board, for more realistic switch/configuration testing. I had some of Kailh's new box silent reds coming, but those were somehow returned to sender, so the slow journey from China begins again on that.
