I think that the 3/50 was a "single board" VME system... and as you say you really couldn't add anything to it. I will pull one out and get some close up shots of the connectors and perhaps the answer can be determined by physical inspection. I also looked at the config file for NetBSD for the sun3 and it very much mentions vme all over the place, but that may not have applied to the 3/50. Is it possible that just VME connector was used for power and the like... but nothing else?? -- Brad Spencer - brad at anduin.eldar.org - KC8VKS http://anduin.eldar.org - & - http://anduin.ipv6.eldar.org [IPv6 only]
