press [L-shift] [2], then [Ports] to see the installed ports. You will see :0:, :1:, and :2:, and possibly :3: if the 2nd 128KB bank is mapped into the 'normal' port addressing scheme. If so, you just access items with the normal :3:ITEM syntax to STO/RCL, etc. If not, and I'm guessing this is the case, then this TDS card implements some non-standard bank access scheme, which I can't help with.
