It is a full-sized ISA compatibility card with the 3DO logic board included, with the input (controllers) and output (video & audio) redirected to the PC.
The 3DO Blaster provided a simple plug and play alternative using the established 3DO standard, instead of building a custom graphics unit that may run into incompatibilities.
As graphics boards of the time were not up to par with the system's needs, a pass-through using a VGA feature connector link was used, thus reserving an area on screen to be used by the 3DO Blaster card's output.
As with the first 3DO system from Panasonic (REAL FZ-1) an FMV daughter-card enabling Video CD playback was planned by Creative, but since the 3DO Blaster failed to achieve momentum, it was never released.
[3] The card was sold with the cables needed, a 3DO controller by Logitech, and two 3DO games on CD: Shock Wave from Electronic Arts and Gridders from Tetragon.
