Schematics can be found all over i-net.

Looking to buy used a small TNC, to connect a small notebook PC and a
Yaesu
VX-5R. Everything (1 kg notebook, its 12v power adapter, TNC, X-5R with
its 12vDC power adapter) must fit in my briefcase with room to spare.

You kind on-topic assistance is appreciated.
