This is the only known copy of Tumbleweeds. Note the
writing on the label that calls this the Puffer Demo, and that is
what is displayed on the splash screen as well. The EPROM
inside properly names the game Tumbleweeds however.
Unfortunately the label is correct and there are no controls
implemented in this early demo, so the player can only watch as
tumbleweeds quickly zig zag down the screen. Internal memos
mention that game was actually finished so a more complete version
may still exist somewhere.
Note the unusual board this prototype uses? This prototype
is only 8K so a smaller two socket production board was used
instead of the larger four socket 5200 EPROM board.
