Hi you all!
In 17/11/2011 Tony Duell asked for the datasheet of SAA5070. Did yo got
it, Tony? I'm looking for it too.
Thanks

What is its function as I have a pile of Mullard/Philips databooks

I got the databook with its datasheet. Unfortunately there are no info
about programming, but for me that is enough. Thanks you all!

Hi you all!

it, Tony? I'm looking for it too.
No, I am still loking for it. I amanged to deduce some of the pinouts,
but the official data would still be interesting.
The SAA5070 is the 'LUCY' IC. It's the 'extra' member of the original
teletext chipset (SAA5000/5010/5020/5030/5040/5050) and is a 1200/75 buad
modem and some I/O ports. Together with some of the teletext ICs (in
particular the SAA5020 timing chain and the SAA50505 chracter generator,
but sometimes the others were used too), 1K of RAM, some glue logic and a
microcontroller, it was used to make a Prestel set.
It was quite common in Prestel sets, from Philips and others. It was also
used io the UK Commodore 64 Prested cartridge. And probably elsewhere too.

Hi, I dont have , or cant find as I thought I did have it, the actual data
sheet but I do have the Mullard Technical publication, M81-0001, "LSI
circuits for teletext and viedata THE LUCY GENERATION" and this has a
circuit diagram which shows the pinouts of the 5070 if this would help?

Yes, the data sheet was not published in the common data book that
included the rest of the teletext IC chipset.
I thought I had the data sheet somewhere too. Doubtless it will turn up
sometime.

That does sound useful. If you have it electronically, or can scan the
page(s) with the SAA5070 pinout, could you send it to my other account at
tony_duell at yahoo.co.uk
THnaks in advance.

There are only 4 pages of info, but here it is...(sent to Tony)

THank you, and thanks to the other chap who sent me the 2 pages of
schematic. I how have the pinout of the Lucy IC, which will make sorting
out the hardware a lot easier. Programming information (internal
registers, etc) would be handy, so if it ever turns up, I am still
looking for it...

Sometime in the 80s I bought a LUCY board for somewere, Display electronic I
think, AIR it had some data sheets with it , it sat in the same box in my
store till I did a " tidy up " last year, now I think its someweer in my
othere store, will have a look next time im there.

I can dump the EPROM of the videotext terminal if you feel like. it has
a 8039 or something like that.

There's a little bit of information on pp. 166-169 of this PDF that I found
rattling around:
