DIYbanter - TV without SCART

is it possible to make RGB SCART connector on a TV that doesn't have
one? (its a Toshiba TV and has only composite input)
how easy/hard would it be?

Given that you can pick up reasonable CRT TV's for free these days you'd
wnat a special reason for modifying that one. This TV wouldn't be an LCD
one by any chance?

Get the datasheet for your set, the PAL decoder chip and then find the
service sheet for another set that uses the same (or near) chip, and has
SCART. Between all that information you should have what you need to
figure it out. Make sure that your set does not have a live chassis, and
make sure your modifications are safe!

Reminds me of an old project I did with a 16" Microvitec bare frame RGB
TTL monitor pulled from an old games machine, converting it into a
colour TV with teletext. Bypassed some TTL buffers and managed to drive
linear signals to the guns, fitted a 'Manor Supplies' PAL decoder kit
(which actually was designed for another Microvitec monitor - these were
popular in UK schools for use with the BBC Microcomputer) and got a
'sandcastle' pulse generated from the inwards of the monitor PCB to
interface the decoder. Teletext (Mullard SAA50xx series) was added from
another PCB ripped out of another TV set (even got fast blanking and
subtitles going), and the remote keypad was from an old Texas
Instruments LED calculator (which should have been kept intact and
Ebayed today)...

Happy days - the whole thing didn't have much of a case, and family
members and friends regarded this very much mains live innovation with
suspicion. I wasn't much good at metalwork or woodwork as I am now,
cardboard seemed a lot easier to work with....

'Kids', don't try this at home ;-)
