emulatorII-list

hi paul,

1st you must disconnect the powersupply from the mainboard to check it for
shortcuts.
the emulator has a switching power supply with a protection circuit, this
means the powersupply
don´t work if there is a shortcut on the eII mainboard. check between
"ground" and the +5v pin,
with an "ohm meter" (i don´t know the right word in english, sorry), if you
get "0 ohms" or "10-20 ohms" you have a bigger problem, the emulator have a
shortcut on the mainboard !!!!

if not ,it´s easy to use a standart pc powersupply in the emulator,you can
,with a little technical background, change it by youself.
i have added to this mail the schematics from the eII powersupply. other
informations are availible
from "www.emulatorarchives.com) - a very nice page !!

hope this will help you

Betreff: [emulatorII-list] Dead E2


Hello All,

I've just bought a dead EII with some library and OS3.1 (if it works).

I was told by the previous owner that he plugged a CD-ROM unit into
the RS interface and the whole thing blew.  I've checked fuses etc
which all appear OK.  Kinda guessing I need a replacement PSU !!

Thing is... where do you get one ?  also have three broken keys - Any
ideas ?

Cheers for any help
Paul
