Hi. I converted a VAXstation 4000/60 to a /90 by replacing the main system board. The new machine works well: KA49-A V1.0-006-V4.0 08-00-2B-37-58-9D 32MB OK 83 BOOT SYS but when I plug in the old graphics board from the /60 I get: KA49-A V1.0-006-V4.0 08-00-2B-37-58-9D 32MB ?? 016 2 0000 Is the /60 graphics board not compatible with the /90 main system board? -- tsch??, Jochen Homepage: http://www.unixag-kl.fh-kl.de/~jkunz/
