Spread Intro (1991?, ECS File)

Reviewed by Glenn Lunder

A nice logo at the top, a sine scroller and some stars - and a quite stonking chipmusic tune. Nice - nothing more, nothing less.
tested A1200/030-50/2mb chip, 4mb fast/3.0.
Note: Incompatible. Runs a little while with KillAGA, then Guru's.

Plasma Intro (1991, 10.3, ECS Intro)

Reviewed by Glenn Lunder

First of all, I named this intro like I did because that's what it is - an intro with plasma :) It has no actual name, so I just did it like that. The logo is the same as in the Spread Intro, btw, and apart from that there's a sinescroller over the plasmathing in the middle of the screen and a small textplotter under the logo at the top. Nothing awesome, but ok for what it is.
