(This is a repost; my first attempt seems to have vanished into the aether)

Hi guys,
   Apologies for the slight OT-ness of this post, but 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 Philips/Signetics/Mullard "SAA5240 
User's Manual" to hand? If so, I could do with scans or photocopies of 
parts of it, especially the stuff about Ghost Row mode. I'm also open to 
buying the book outright if anyone wants to get rid of theirs...

FWIW, I suspect the SAA5243 or SAA5246 manual would be just as good, the 
register maps seem to be more or less identical (based on the 
datasheets). Hardly surprising, really.

Thanks.
