The hard disk seems to power up ok. The "lattice" pattern on the screen, I attribute to the initial state of the video RAMS...no CPU action to clear the screen. A scope on the 68010 doesn't show any of the activity I would expect to see (address strobe, etc) Clock is present and the control signals look reasonable, but I don't know enough about 68000's to tell for sure. Anyone have any tips for troubleshooting (sans schematics, unfortunately). Thanks for any help. /gary Gary Grebus grebus@lando.dec.com decwrl!lando.dec.com!grebus 508-264-5789 (work) 603-673-8299 (home)
