Description
I am clearing space in the house, I have a bunch of 1800 boards and a batch of prototypes of the elusive Katana60 Pro and Tsuka60 Pro PCBs.
The prices are somewhat negotiable and do not include shipping (but depending on where you are and what you ordered, that should cost somewhere between 5-20).

First, the 1800 boards
| Code | Name | Notes | Cost |

| 1 | TKC1800 Build | PCB rev 1.1, incredibly well lubed cherry blacks – NO SCRATCH, smoothest I’ve ever tried. Flashed with via firmware. | |
| 2 | Lauer Fischer GMK 1800 Build | Cherry blacks (scratchy, lots of character), dyesub caps (PBT). | 20 |
| 3 | Lauer Fischer GMK 1800 Build | Cherry blacks (scratchy, lots of character), dyesub caps (PBT). Slight yellowing. | 20 |
| 4 | Lauer Fischer GMK 1800 Build | Cherry blacks (scratchy, lots of character), dyesub caps (PBT). Heavy yellowing | 20 |

PSA: The Katana60 and Tsuka60 boards in this listing are testing and (unless otherwise stated) working prototypes. I flashed them with Via compatible firmware, and made sure they are working. To use them with Via, you will need the appropriate layout file [link to json layouts]. To avoid heartache, I will test again before shipping.
You will notice in the pictures that some of the prototypes have wires soldered on the back, this is to fix issues I found in those designs. The boards in this listing all work unless stated otherwise. I'm committed to supporting you in getting them programmed the way you want. Otherwise, the boards are provided as is.
In some cases, there are switches and keycaps in the pictures, but generally I offer a price with and without those. Your choice.
Note about case compatility
The first two Katana60 releases were designed to be compatible with standard 60% keyboards, there was some switch modding necessary due to overlapping support posts. My recommendation with the Pro variants is to cut all posts off except the two outer posts (centre-left and centre-right - I provided a picture in the gallery). As well as cleanly solving the overlap issue, it provides a much nicer, bouncy feel, since the board is floating.
The alternative is to reach out to falbatech.click - he sells 60% keyboards that are fully compatible with the Katana60 Pro (and is also adding the Tsuka60 Pro to his product list - I added a picture of that to the gallery too).
