I was given this little thing a while back, haven't done anything
with it yet...

There's this board, no particular identifying marks on just what it
is. The oddest BNC I've ever seen on top, some switches down the
left side that seem to be for selecting sensitivity and coupling,
some DC input connectors on the top to power the thing, five buttons
labeled OK, +, -, SEL, and RESET. A couple of pin headers and a USB
micro connector on the bottom. A plug-in board labeled "2.4" TFT LCD.

Two bits of paper came with it. One is labeled Oscilloscope DIY Kit
User Manual but it seems to be assembly instructions. This bears the
numbers 138803K and 13804K, no indication as to which unit I have
here. The other paper has "How to Use" calling out the "Display and
Controls". And some stuff about "probe calibration". On the back of
that one are schematics that are barely readable. With a magnifying
glass I see them showing power input as "9.39V". (!) Apparently some
of this thing runs at 3.3V also.

There's no case, though I'm told that one is available. Not told
where, though.

Have any of you guys run across anything like this? I'm a little
dubious as to how useful this thing might turn out to be, haven't yet
gotten around to digging out an appropriate wall wart to power it
up...
