Thanks Steve, the PSU produced the voltages you stated and I checked
with and without the main PCB connected so as to rule out a faulty
componenet pulling the supply down under load.
I do not have a schematic and have browsed the web for a service manual
or the similar but did not come up with anything which is why I
basically joined the user group for further help.
With the system EPROM is guess I was getting hopefull.
