The Sharp HB-3000 is a RS-232C interface without MSX-BASiC support. Official product name is 'Interface de Comunicaçâo'.

It contains a ROM with a program giving access to videotex, the Cirandão network and allowing communication between two computers. A modem is required to enjoy all these possibilities, but Sharp Brazil has never commercialised a modem.

There were two versions of this interface, the second one (under reference HB-3001) probably corrects a bug in the 40 column text mode and adds supports for the 80 column mode.
