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. Bill
