[sdiy] Repairing a Simmons SDE

[Christian Oncken]

I've got a broken Simmons SDE.  I desperately want to fix it.  It was cool
as hell when it worked.

Its been broken for at least 2 years.  It started flaking out and loosing
patches, I suspected the battery so I replaced that... then it wouldnt turn
on unless I power cycled it a bunch.  Then it completely gave out... lights
would blink in random ways and the display would show garbage.  Now it wont
even turn on...

Any help here?  Anyone have experience/tips/knowledge about the SDE?  I'm
suspecting the power supply now, but I dont know what the correct voltages
are supposed to be.  Also may be that the EEPROM has gone bad?  Any way to
check this, and if its bad, how would I go about replacing it?

I really want to get this thing working again.  They arent too expensive to
buy used, but kinda hard to find... I havent seen one since I bought mine
about 4 years ago.

Thanks, this is a wonderful list.
