Too bright can be fixed by trial adjustable pot then use new resistors.
I'm curious about this game machine, how is it played? I remember seeing these on tv ads years ago when I was a child.
Cheers,
It has 6 games, tick tak toe you can play against the computer or "merlin" you have to press the Comp Turn button after you make a move but this is good when you want to cheat as merlin doesn't have programming to know when you make a move, so you can literally put three in a row and win before he makes his first move
Another is to get a complete square without a red one in the middle, each button changes other spots and is fun till you work out the pattern
Blackjack is another but I haven't played this one much
A music one where merlin will remember upto 48 notes pressed and then play it back, merlin has 48 bytes of ram
Echo which is similar to Simon you get to select how many sounds you have to remember upto 9
And last is mindbender you select how many digits for a number that merlin makes you guess what number it is if you select 2 digits and one of your numbers from a guess is in the game he will tell you but two digits is very easy it's hard at 9 digits
The sounds made remind me of some Atari 2600 games, my sister had a merlin when she was a kid so as a late Xmas pressie she's getting this, the pcb is just 11 LEDs, 1 electrolytic cap, 1 ceramic cap, an ic, some resistors and a touch sensitive plastic film for button presses like some keyboards, the ic chip must be the CPU with ram and program
