Unix v6 and 11/23 - Success!

Hi All: Thanks for the assistance today. Thoughts about the DEC firmware wanting a NOP in early bytes of sector 0 must have been correct. I was able to get to ODT via the HALT button, and entered a 4 instruction bootstrap (basically, read current sector into memory starting at 0 and wait), halted the machine, entered "0G" via ODT, and watched with glee as Unix came up. Some confusion ensued when I couldn't get it to work a second time, but then I realized that due to the simplicity of the bootstrap, the heads would have to be over sector 0 for this to work. Unloading and reloading the pack reset the heads to sector zero, and the boot process is now easily repeatable. A better bootstrap would help in the longer run. Single user mode comes up fine, I get a panic while trying to get it to come up in multi-user, but it's great progress for the day. Thanks to all on the list who replied with suggestions.
