Timer/Counter Clock Inputs

Projects Programming

Is this a programming question?
It is,at least partly.
My AtMega has Timer/Counter Clock Inputs T0, T1, T3, T4 and T5. Arduino Mega 2560 has pins connected only to T0/PD7=pin 38 and T5/PL2 = pin 47. I need at least 2 more clock inputs because I need to use one clock output (OC) as input to other Timer/counters. One possibility is to try soldering leads to the unconnected T1, T3 and T4 legs, but they are so tightly spaced that it may not be easy to do.
Is there an Arduino board with all Timer/Counter Clock Inputs T0-T5 or at least 5 of them available in the edge connectors?
thx

I know that the Seeedstudios equivalent of the Mega brings more pins out
to headers, but offhand I've no idea if it brings all those Tn pins out.

Thanks MarkT !
It seems Seeedstudio Mega indeed has all the Tn pins available.
