[c-nsp] Best Cisco 3620 IOS

[Brandon]

I've got a Cisco 3620 here that I've been playing around with. I'm wondering
if anyone knows the best version of IOS that would run on it.

I understand that you need to have a minimum amount of memory to run some
version of IOS and I'm willing to buy some more RAM for this machine if
that's what I need to do.

I apologize if this question seems out of place or really simple. I'm young
and this is my first go at Cisco routers.
