Last year I purchased what I thought was a Model-A Raspberry Pi from Element-14/Newark (US). Since I later had a project that needed a Model-B, I bought one of those also, a few weeks ago.
Recently, I was checking out the differences between the two models and found that, according to various sources, The Model-B has 2 x USB ports (1 on the Model-A) and an Ethernet port (none on the Model-A) as well as a memory size difference.
Now my "Model-A" has both an Ethernet port and two USB ports so I'm confused. Is it, in fact a Model-B (which I didn't think was around when I bought the first one)? Is my information on the model differences wrong? I would appreciate it if someone could shed some light on this and clear up my confusion.
Also, what's the easiest way to check the amount of memory?
