Can you give some info what is on these disks. Do you have a running program from them.

Usually t2 cards can be extracted from tis2000 but they are split in smaller files. A software download can be performed with a tech2 attached to the pc. It will write the current card from the tis version. I think first versions of tis2000 is around 2001-2002, Not sure when tech2 was launched, and when 32mb cards were introduced.
