Thanks for the warm welcome everyone.
To answer some of the questions, it was pretty messy in there and I cleaned cartridge slot and the top of the main board and surrounding areas so maybe it was that that cured it.
Yes, I've noted that all the stripped down intellivisions on YouTube look different inside to mine. Was gonna ask why but it must be because they are all NTSC and as such we're built differently.
Not sure about getting a cover, maybe later. At the moment I just like looking over at it sitting on my rack, love it
My father was very generous when I was a kid, I remember have pretty much every game including the computer module, sound synthesizer module and melody blaster with keyboard.
I remember my favourite games being :
Advanced Dungeons and Dragons
Dracula
Shark Shark
Tron Deadly Discs
Night Stalker
Utopia
Sub Hunt
Although I remember my favourites swapping all the time back then and I'm sure I'm forgetting some.
