OK, so this thread pushed my to pursue playing with DT/6000.  If anyone has documentation on how exactly everything fits together, please let me know...if someone miraculously has a copy of DT/6000 in their archive, I could use a copy.


Feel free to ping me off list to keep the noise here down.

that said, if anyone needs any of them, let me know: just shipping cost.
