Hey Michael. Check out the 3560 software config guide under spanning-tree. Looks like according to the latest docs PVST+ and RPVST+ support 128 and MST supports 65 instances. Frankly this surprised me, because all the books usually say MST supports 64 instances. Maybe 64+instance 0 ? Anyways, that is where it is at.
" In PVST+ or rapid-PVST+ mode, the switch supports up to 128 spanning-tree instances. In MSTP mode, the switch supports up to 65 MST instances. The number of VLANs that can be mapped to a particular MST instance is unlimited."
