The board is from a Ferguson T14T
(Thomson TX91 chassis?) and has two ICs
onboard - a Texas Instruments IC labelled:
EUROTEXT
TELETEXT DECODER
CF70204NW
59A5V3W
The other one is also TI, labelled:
58D71DT
CF72306
DATA SLICER
Anyone got a Ferguson T14T or Thomson TX91 service manual? I need the part
number of the TTX decoder mentioned in the schematic. I think it originally
used a Philips SAA52xx IC, not sure though.
Thanks.
