I'm getting ready to throw this darn machine out the window. Something's wrong, and I can't stand it. The GVP 040 board on loan to my local dealer has functioned flawlessly in both a stock A2000 rev 6, and a fully-loaded Toaster system. I can install InterChange Plus on my machine here without indicent. Installation proceeds smoothly on the dealer's machines, too – except on the A4000, when I try to start InterChange itself, either from the WB or CLI, it sometimes says "Out of memory" on a requester. Two-three attempts later, it launches fine. I'm running release 2.01 here. I'm thinking about buying a new A2000, either a complete machine or a new motherboard. Does CBM dev sales sell motherboards, or am I dreaming? I want to install from virgin 2.01 or 2.1 disks and slowly restore everything else. I think that should waste a good day or two, won't it?
