Haven't abandoned the thread, just haven't had a chance to get back to the site. Should be there tomorrow. BTW - double checked the jumper, its good.

Unfortunately, I don't have a spare 4-slot, but I do have a 7 I can use to test. Thanks, for finding that old thread - I looked at a bunch, didn't find that one.
I'll post what I find.

Need a little help here - I am trying to re-purpose some old hardware. I have 2 old SLC5/04 B processors (+15 yrs?), that are giving me the same problem. After a power cycle, they boot to a solid fault light - no comms. Cycling the keyswitch has no effect. Popping the processor from the rack and reseating it, powers up in a default state - it will not reload automatically from the EEPROM (when I establish comms, I can reload from the EEPROM or download the program from RSLogix). I can't read the processor fault. The battery is good. The rack was scavenged, I have no idea its history. Also in the 4-slot rack are DI, DO and RIO Scanner cards.
I would consider my self a competent programmer, but no A-B expert. Any ideas here would be appreciated.
