Description
TIMESTAMP
Final remaining items from my previous listings. Getting rid of all the these as I am leaving the hobby.
Bundles preferred, big discounts. All prices include shipping to CONUS
QMK Through-hole (TH) IBM Model F and Beamspring Converter - 50 USD
This is based on this Deskthority project by pandrew
With the nature of the 3 included plugboards, the female pin headers and Card Edge connectors have been left unsoldered for the buyer to complete. Alternatively, you can let me know what keyboard you'll need this for and I'll solder it.
I have 2 available, each will come with a Solenoid driver and 6-pin cable connectors

Do note, this controller revision 0.1.1 does not natively support LED lock lights for the Model F AT, which revision 0.1.3 does.
PBTFans Tape and Radio Keycap Set - 50 USD
This is the Yellow Base, Numpad, and Spacebars Kit. Mounted once and placed back in the included tray.
DROP DCX BOW Keyset - 40 USD
This is the Base and Spacebars kit, these have been opened but never mounted.
UniCusMech? AFSA Keyset “Monster” - 10 USD, free if bundled
A cheap keyset I got from Amazon a while back. Even though it was described as SA Profile, it is closer to be AFSA profile instead, being about a millimeter shorter than SA. See the assembled photo on an 1800 board for reference.
Send a message if you have any questions , thanks
