Diagnosing non-functional Emax

2014-02-17 by David Sotnick

Hi all,

Now it's my turn… I'm sad to report that my beloved Emax SE Rack which I upgraded to SCSI and slim floppy is no longer booting.

Symptoms are: PSU voltages look good at the drive power connector. All LEDs on the front panel come on at power-on except load and enter. No LCD display and no floppy or CF reader activity. :-(

I have re-seated all cables but have not yet removed and re-seated any socketed ICs. It has just been sitting in a rack, so nothing has been jostled.

Any suggestions on where to start?

-Dave

p.s. even more frustrating: I missed out on a $60 working Emax SE on a local Craig's list ad which posted the day before I discovered my Emax was dead. :-(
