Indeed, been ages since I player the old versions..
do remember one the best tips though:
Free Upgrades
If you're short on cash but desperately need to upgrade your weapons, ammo, or other items, hire a runner who you don't particularly like. Take all of his items and kill him off. Viola!
Nowadays they just do that to deckers.
So if you are rolling up a decker and everyone else suddenly puts resources at E, watch your back.
