For the record, the Zeta Wolfram, if I recall correctly, started from some tweaks I added to the original G1 adv file trying to add a little extra interactive stuff to the world, namely having new corporate interests move into Hyoge if you successfully reopen the old mine. The original version of the Zeta Wolfram was an upgraded Wolfram available for sale from the shopkeeper I wrote in.
