Ah. This one.
Out of the three consoles given to us in Core Set, I used to despise this one the most.
This reminds me of what dad used to say: git gud, son.
Compare Desperado. Gives you one mem and also one credit for every run that is successful. Definitely has its merits, yes, but the run has to end in an indisputable success in order for you to claim your prize. And, let's face it, you are not going to run more than two times a turn, save for the rare occurences when you'll really have to, and rarely all of them will really be successful. You either run good or run a lot.
Toolbox gives you two creds. Up front-like, no matter how many runs you are going to make during your turn, you get two creds. The catch? They have to be spent using icebreakers. And you know who uses icebreakers a lot? Yeah, you guessed it - everyone. It is your favourite black hole you try to clog with money bills after you're about done setting your rig up. Refunds really quickly, too, as these are two creds a turn you won't spend on breaking subroutines - you can now spend them somewhere else.
What else is in the box? Two mem units. Mostly useless, except, you know, for the cases when you'd like to have your full suite of breakers, a backdoor or a bitcoin miner AND a sniffer. So yeah, useless. Totally. Right?
And two additional links, because every good workplace has at least a solid sheet of tinfoil to make hats with. What's there to do with two links? They enable cloud breakers right off the bat, for instance, which lets you drop even more things on the board. Avoiding certain death by helluva tags and missile launchers is made a bit easier. Only a few brands of lesser tracer ICE will get neutered like a kitty-cat from a good house, but most of them you'll see blunted just enough to avoid any serious harm they might've caused. Link is a really a good thing to have which most of us completely underestimate.
To sum things up, it is kinda double Desperado with some additional link to sweeten the deal. It also gives you creds indiscriminately, no matter if you manage the run or not, while also enhancing quality runs over quantity of runs.
By the way, do you know what is a cool multifunctional console that doesn't cost nine creds?
The answer: Modded Toolbox. That's a joke I've just made up. I know it isn't funny. Shut up.
