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!

There are links to connectors on the page. You may have to open the case
so you see what din jacks are wired to what on the connector on the board.

Thank you! It's an interesting machine. It will be more interesting if
I can get it running. I think the power supply is toast.

Hi Jon,
I might be interested and live in the Indianapolis area.

If it's not obvious from opening the case and inspecting what this
sockets are connected to, then I think I'd check the PSU, power up, and
try a composite monitor on each socket in turn to see fi you get
recognisable video. You will not damage either the machine or the monitor
if you connect the latter to one of the tape sockets.

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
