The computer map would be too good then i reckon
Not necessarily.
If it's just showing us the locations of the items, even for just a few turns, there's still the possibility (the likelyhood) that we haven't explored those areas yet. Which means they could be full of enemies. Not something you necessarily wanna run into when low on health. I think this could actually enhance gameplay, because you have to weigh the risks against the benefits. Also, you could code it so that the powerups are all a grey color. So the health pack could be anything the the "+" represents. Or the "^" represents. That would make it a little more difficult. :)
