Thanks guys for the advice,
I started the retrobrighting - in the sunlight only. I put the keys caps out today. The black ones have come out quite good after just one day. They are still black, but the writing has whitened up just nice - given the comment of risk of greying the caps --- i will stop with the black caps now. The white keys still need a bit more time --- not sure of the weather over the next few days - will keep an eye on it. Also only just put the case and printer top out today - the printer was the most yellow - that might struggle in the sun only...
I tested with the cassette player a couple of days ago - just out in the sun - although it was rather overcast days - after just 2 days 1/2 days in mostly overcast days -- it came out rather nicely - i brought it in today as it seem like enough.
Unfortunately for the cassette player, its has received some serious injuries to the plastic - like its been attacked with a soldering iron. I think it will have to live with those scares for the rest of its existence.
The keys themselves have loosen up a bit - think just using them a bit has helped -- but I will have a close look at the guide you link thru Ewan - much appreciated.
In regards to getting the colour working -- I need to do some more experimenting to get the intensity signals right - i think i need to buffer the TTL output, before doing the resister grading... I have sketched out a design that will allow me to experiment - but not with the breadboard --- that was a bit too precarious to work with. Need to get a proper 15 -sub connection.
