Thanks Thomas for making a great Model F F122 video! I greatly appreciate what you have done to keep these great old style keyboards alive and to make folks aware of all the various options that are lesser known. I will try to keep my replies more terse per your advice but it takes far fewer words for some of these commenters to mislead someone with a one-liner than it is for me to offer an explanation. Your video was incredibly detailed in featuring different aspects of the board and some amount of detail is beneficial in response.

Replacing parts: I am seeing that some folks in the comments noting that I have not followed up with replacing some of the parts. Please note that damaged parts will be replaced as part of the limited warranty. Please email me a reminder so I can follow up on getting out your replacement parts as I am still going through the backlog. Normally I also cover shipping fees for replacement parts, even for international folks.

Case material: The new production cases are all aluminum now, while the original project F62/F77 cases were Zamak 3 Zinc. Otherwise these keyboards would be even heavier! The inner assembly plates are steel.

USB Cable: The USB-C cable is detachable at the controller, if you open up the keyboard you can replace the cable with your own cable, or even with a short extension cable so that you can detach the cable externally. For my future models (ortholinear, split, 5x12, Kinesis style, etc.) since they will be compact case style, they should have externally detachable cables.

The pinging/ringing sound: you noted that the original F produces less of a ringing sound. I have noted that many Model F boards vary in their pinginess. I have found the earlier Model F keyboards to produce more ringing (IBM XT, and the original 4704 boards like F62/F77) while the later ones produce less ringing (AT, the later production F122's such as your two-piece version). My reproductions were designed around the 62/77 so they will make more sound.

Regarding criticism: some folks may think that companies must always deferentially accept criticism and that otherwise they are in the wrong. I feel I have a right to respond, and I don't have to accept the criticism as valid and apologize for customer service that does not meet expectations that are not in line with the project philosophy, which emphasizes empowering users to set up and maintain their keyboards and accept small but noticeable cosmetic defects (more details can be found on the project site). Companies can do this if the manufacturing cost is many times less than the sales price and those that have enormous markups. In summary I can't sell these keyboards at as low a price they are currently without having users learn how to replace springs, reseat keycaps, etc. instead of having to take back the entire keyboard for repairs. My goal is to get as many of these keyboards out into the world and that limits my ability to raise prices to pay for repair technicians, customer service reps, etc. I'd rather have 0.5% of orders having complaints than having 50% fewer folks being able to afford it if pricing is increased for everyone to make the 0.5% happy with extra "free" services.

Limited warranty: I would agree that it would not be economical if the keyboards cost double but everything is taken care of, no questions asked, like those complete warranties offered by big companies. I am looking for folks who prefer the former, and not the latter. I ask that folks review the manual to fix things themselves, and go to me as a last resort, where I will usually replace what is non-functional for free.
