Intervlan routing and 3Com 4200 Switch

Okay here is my problem. I have a 3Com 4200 Core Switch handling all my vlan routing and we are looking to replace this switch with our Cisco 3570.
So this is what the person before me was trying to do.
3Com 4200 <<<<

We are have three vlans setup on the Cisco 3750 for testing and able to ping the ip address of each vlan ip address from PC behind the Cisco 2960 on different access vlans. I have a default route set in the Cisco 3750 to the 3Com. The problem is I can not ping the 3com switch from PC but can from the Cisco 2960 and the Cisco 3750. What am I missing?

so the 3com is still doing routing? Does it have a route back to the subnets the PC are on?
