Supercomputers, fishing for information

I'm making arrangements to have four (mini-)supercomputers from the 1980's shipped to me. In the mean time, I'm trying to find out what I can about these systems, so this is a fishing expedition. The systems are: * Convex C1-XP * Convex C1-XL * Intel iPSC/860 * Ardent Titan Pictures of these can be found on my website, at http://www.vaxbarn.com/index.php/collection/27-odd/76-four-supercomputers (click on the thumbnails to see a larger version) I'd like to get in touch with anyone who knows anything about these machines, as well as anyone who may have documentation, but I also have two specific questions: - Can anyone identify the tape drives shown in the pictures? I believe the one in the Intel iPSC/860 is an Exabyte 8mm one, but the ones used on the Convex and the Ardent are a mystery to me. - Does anyone know what the SRM (System Resource Manager) for the iPSC/860 physically looks like? Does it look like a PC, and does it say Intel on the front? Reason I'm asking is that I'm getting these out of an estate, and I need to tell them what to look for. Thanks, Camiel.
