Will not function on displaywriter beam spring keyboards (see my other listing for controllers that work with those keyboards). Only functions on displaywriter beam spring keyboards with removable controllers (they have card edge connectors).
Why is this listing at a higher price compared to the Brand New Model F Keyboards project site? The reason is that this is to account for higher fees on this platform. All controllers arrived from the factory and are now in stock, ready to ship.
I have in stock USB-C xwhatsit displaywriter and USB-C xwhatsit beam spring controllers, xwhatsit solenoid drivers, and am custom making a batch of keyboard solenoids compatible with the xwhatsit solenoid driver.
Please note that this listing requires technical knowledge and following xwhatsit's installation guide. No support is offered by me.
Note: I will not accept returns for any reason, including if you find the item available from me elsewhere at a lower price.
Controller was 100% tested working by me; however given the age of beam spring equipment used with this controller, item in this listing is sold as is, for parts or repair.
