Need Tandy 2500SX Deskmate Disks

Would anyone happen to have Tandy 2500 SX/20 Deskmate disks? These were specific to the computer - I actually have disks 1 and 2, but need disk 3. While I can find the generic Deskmate online, this was specific to the computer as it had it's own built-in DAC sound, and there's apps for it. Jeff aka Bags
