Spider and Spider II - what's the difference?

Looked at the info for Spider II but it says nothing of how it differs from Spider - what exactly is the difference and can the Spider II be “downgraded” to earlier versions of the GHI SDK?

Thanks

@ KorporalKernel -

72MHz vs 120MHz is also what i want to say. :smiley:

There is a nice side by side comparison tool built into the ghi website:

Just add the original spider (under legacy products)
