Dave are you saying that the A2620 has some built-in diagnostics? Is there some trick to accessing this monitor program and the diagnostic? After reading this I tried it without any success. I rebooted, and held down both mouse buttons to get the CPU select screen ("mode list", right?). But once there, typing "M" in ANY case had no visible effect. What should happen to show that you're in the monitor? Is this only present in certain revs of the A2620 boot ROMs? Are there any other goodies in there (assuming I can get in there in the first place)? -- Blaine Gardner @ Evans & Sutherland 580 Arapeen Drive, SLC, Utah 84108 Here: There: (My Amiga running uucp) blgardne@esunix.UUCP blaine@worsel.UUCP {decwrl, utah-cs}!esunix!blgardne utah-cs!caeco!i-core!worsel!blaine
