Posted by Digi.kthese arrived today but I am looking for someone to do RGB conversions in the UK..
Good luck with that.
Been looking for months and I have contacted quite a few that used to do them with no luck.
Avoid Raven Games
unless you want to pay big bucks and they are bodgers of the highest order.
You could try getting a NEC RGB/AV BOX which outputs an amplified RGB scart (nice) and composite+audio L/R
(google is your friend)
No modification required, plugs into the ext bus, but you won't be able to use it in conjunction with a CD unit.
