>>26 Just period and slash.
>>28 ≈ means approximate, and the answer is 64, as was mentioned earlier in this thread.
At any rate, there's only eight characters input, thus 281474976710656 possibilities. One million inputs per second is very poor performance; you can easily get five or six million with a modern processor, and that's not even considering specialized DES-cracking hardware. Multiply by a small distributed network of 30 systems (which isn't at all difficult to get; all you need for this is the CPU and motherboard, and a minimal amount of RAM, so you can build one yourself for less than $300) and you have a very reasonable time of 18 days.
