AST Research Inc, Irvine, California continues to rush out new personal computers, and the latest is the 386SL notebook computer, which provides up to six and a half hours of battery life: the PowerExec’s processor board can be upgraded to 3V 80486 processors for longer battery life, AST said; monochrome models start at $2,500 and $2,800 and colour at $3,500 and $3,900, but street prices will be lower.
