Hi Tony,
I did not see anything unusual on the screen before this happened, however
tonight I will look closer and let you know..
I am planning on disconnecting the power sullpy from the rest of the components
and see what happens if I power it up alone..
I will look very close at the yoke assemble also..
Thanks for your interest.. Very kind of you..
Back to you later...

Hello everyone,
I am needing schematics for an Osborne 01 computer, or some help in
repairing it..
I just purchased it last week and was using it for about 30 minutes (It
had not been used for some 13 years).. Worked perfectly and is in mint
condition.. Then all of a sudden a crackle and smoke poured out.. It
was still working but I quickly turned it off to save it from further
damage..
My first guess (not having seen the machine or the schematics) is that
the flyback (EHT) transformer is breaking down. Was there any change to
the image on the screen (flicker/change in size) when the problem occurred?
Examine the flyback carefully looking for cracks/burning
