Hi Jonathan,
These machines are pretty easy to fix.? I have seen the video connector on the top (more
common) and on the bottom; it may depend on who put the machine together, or who modified
it later.? Anyway, just try plugging each of the outputs to a monitor--no harm will come
if you don't guess right the first time.? From there, it shouldn't be too hard to
figure out the cassette interface.? However, if you just open it up, all will be
revealed.
If you go to http://osiweb.org , you will find some links to useful OSI debugging
resources at the top of the page.? You will find schematics for rev's B, C, and D of
the board there, in the "OSI hardware" section, as well as a SAM's manual
for this board at http://osiweb.org/manuals/SAMS-C1P-Service-Manual.pdf.??
Best regards,
Dave

All,
I've come across one of these systems. Is there any interest in these?
There are 3 RCA jacks on the back, but they aren't labelled. I know
that 2 are for a tape recorder and one is video, but which is which?
Anyone know off-hand? I'd like to verify if it works/runs OK.
It belongs to a friend of mine and he needs to get as much cash out of
it as possible. Any ideas/offers are welcome.
Thanks!
