[time-nuts] OT: 10 MHz data capture, help

I have a old data device that is spitting out TTL data at 10 MHz.
There's just a data line (no clock) but the edges clearly indicate
an internal 10 MHz clock.

I'd like to do a continuous capture of the bits, for up to tens of
minutes, into a PC. That comes to about 1 GB of raw data. I can
handle the decoding of the bits in software after the capture is
done. This is a one-time experiment.

What is the best/quickest/easiest way to capture data like this?
I've looked at various USB or LAN logic analyzer and 'scopes
but most seem to work on batches of data. I need a continuous
capture.
