A USB-C sync and charging adapter for the Palm serial dock connector.
A common problem with other adapters is that they often require a hardware RS-232 serial port,
making use of an additional adapter with modern hardware necessary. There was also a USB-equipped
docking station available but that one is very large, too. Also it has only USB-A so strictly
speaking there is still an adapter required for use with many modern devices.
USB-C all the things!
Thanks to semi-modern electronics everything required for USB to serial conversion, RS-232 level conversion and charging of a Palm PDA equipped with this type of palm serial connector can be squeezed within the space usually occupied by the palm serial connector itself.
