This has documenting value only. But it really shows my Classic II with its 10 MB of RAM (and a 40 MB HD) copying the entire content of a Zip disk 100 MB to a streamer tape 2 GB. None of these items is 'younger' than 15 years (maybe the Zip is).
The process took about 15 minutes.
Set the playback to full screen and watch the files being written to tape!
This really has to be repeated with a better illumination; this was the first attempt after installing the 'RetroSpect' software into the System 7.5.
