I'm trying to build some sort of Teletext capture and decode circuit on a 
MultiBus board for use with our UNIX network.

However I'm having problems finding any ICs that will simplify the job.

Does anyone know anything about the signetics chips:
SAA5020, SAA5030, SAA5040,
They've been discontinued but I know a supplier who has them. Anyone know if
they provide some means of processor interface? Are they IIC controlled?

I know Plessey do a chip set. Has anyone used it before - any comments welcome..

Finally, how do you talk to an IIC interface? Are there any chips for 
providing a processor interface to this.

Any advice, comments, data would be very welcome. E-Mail me at :

gtaylor@cs.strath.ac.uk

Thanks.
