SUBJECT: Analysis of an unknown
digital computing device
We have recently obtained a device
that seems to be an advanced digital
computing system. The origin of this
device is unknown.
Our engineering team have identified
some of the circuits, and managed to
extract the data from the device's
persistent storage.
We need your immediate help with
reverse engineering the device.
