Thank you Nick, that’s actually very helpful.
I got it started yesterday by pure luck. After a number of on/off switch flips, it proceeded and formated the ram. Then when the unit loaded as dsp7000 (only engine A was available), I did a full reset from ‘Setup’ menu. Booted as Orville and worked for some time with occasional random self re-boot.
Today cold start and it’s back on endless boot (pressing 8 does not help), even though I installed a new battery..
Looking under the hood, the PAL is already soldered. Perhaps it’s worth reflowing, something I could do myself. If that doesn’t help, would NVRAM replacement be the next call? Does it contain any code or can I simply find a replacement and solder it?
I understand, I’m asking a lot, however really appreciate your expertise and answers.
Thank you
