Hi guys,
I seem to recall there being a few folks here with copies of old
Philips Semiconductor, Signetics and Mullard databooks kicking around...
Basically, I've dug my old Ground Control UTA-1 "Universal Teletext
Adapter" out of the cupboard, and I'd rather like to make it work on my
Linux box. I've found some details on the CITAC chip that controls the
tuning, and a bit more info on the tuner module, so at this point I can
connect it up, get an I2C ACK from the CITAC, and tune in a channel.
Problem is, my datasheet for the SAA5240A Teletext controller chip is
either an early release, or is just plain incomplete. For a start,
there's a reference to Ghost Rows Mode, which from what I can tell
allows access to the "extended" Teletext data rows which carry the
Fastext page-jumping data.
Does anyone have a copy of the "SAA5240 user's manual" to hand?
FWIW, I suspect the SAA5243 manual would be just as good, the register
maps seem to be mostly identical...
Thanks.
