Default Wanted: Service Manual Oscilloscope HUNG CHANG 5504

Hi all out there....
I've just come a cross a oscilloscope made by HUNG CHANG and the model
is 5504.
It's a 2 ch. 40 Mhz oscilloscope. It was manufactured, as I
understand, someware in the late 1980 (1988???)
I have search around the net, without any luck. Is there someone
knowing a site there I can find a service manual?
Or... is there someone having such a service manual (with schematic),
and would like me to have a copy for a small sum of money, I would be
very happy.
Please let me know

With the best regards from Sweden
