Has anyone archived the DEC InfoServer 100 firmware anywhere? I see that CHM has one, http://www.computerhistory.org/collections/catalog/102682746 Is the InfoServer 100 motherboard identical to that of the MicroVAX 3100 Model 20, except for the firmware? From information I've found on the net that appears that it might be the case but I haven't found a definitive answer on that. I have a MicroVAX 3100 Model 20 that isn't too interesting and it might be more interesting if it could be converted to an InfoServer 100 with a firmware swap. -Glen
