Scramble: Two Remakes
I stumbled upon a nice looking Scramble clone by Mersey Remakes called Scramble: Chrome. It has all the classic elements of the game but with modern background graphics and 3D spaceships. This game is for Windows and about 8 MB.
You can also find another portable Scramble remake here. This one features a simple classic background but with modern looking ships. This game is much smaller at 2.63 MB.
