|  Re: C16 Expansion Port to User Port
@C16Terminal: WiModem's manual (rev. Jan. 30, 2019) states that the product is compatible with Plus/4. You should consult with Jim Drew what that means.
If he confirms that it is really compatible with Plus/4, then you should build a compatible (to Plus/4) User Port. MCes wrote that Jácint's implementation will not work. If that's true, you should build either one based on the original Plus/4 schematics and components, or you ask MCes to design or build a modernized one for you.
However, if the WiModem is not really compatible, than build the one you posted the schematics for and you'll have a probably working but incompatible User Port.
