Hope this helps.
Just chiming in...I am the person who provided Warner with the VENIX
disks. I probably have more RAM than I need in my machines (I have three
and I think I have an A, B, and a regular Rainbow here. All of this talk
has peaked my interest to set mine up and see if the new Rainbow I just got
this week works. In addition to VENIX I have a lot of other disks and
parts.
Not saying I plan to sell anything in particular, but once I assess my
systems and get one good maxed out working system going I will probably
sell off the spare parts.
