I'm setting up my #BBCMicro to go online (to BBSs), like I did with my C64. In that process I'm planning on having the BBC Micro itself power the WiFi Modem. Got a connector from Mark at RetroClinic. Soldered, crimped and heat-shrinked.
It works!!!!!! Modem powered by the #BBCMicro itself and it "dials" into a BBS just perfectly!!! I'm over the moon! BBS access via Commstar loaded from ROM chip.
