In a computer system, a direct access, independently arbitrated video bus (connected to a personal computer (PC) -compatible video subsystem) is directly coupled to one or more dual-ported processors to eliminate video cycle traffic over the system bus or buses and I/O bus, thereby improving system performance. The preferred embodiment architecture has, in addition to the video bus, multiple processors coupled to at least two independently arbitrated system buses which are coupled to at least two independently arbitrated input/output (I/O) buses, to provide for rapid bus information signal transfer rates.

The present invention discloses a method and apparatus for performing data compression during monitor refresh operations. In one embodiment, it is envisioned that the compression functions would be performed in a refresh compaction device and the de-compression functions would be performed in a RAMDAC, thereby requiring only the transfer of compressed data between the refresh compaction device and the RAMDAC. In an alternative embodiment, it is envisioned that both the compression and de-compression functions would be performed in the refresh compaction device. Regardless of implementation, a 'critical fill' level is determined during compression and a 'critical fill' interrupt is generated during de-compression to gain control of the frame buffer before the compressed digital data is fully depleted.

A training aid for calf roping comprises a calf shaped body supported by horizontal and upright skid runners. The runners hold the body above ground to be pulled along as a roping target for a calf roper. The calf shaped body includes a head portion that is tapered smoothly from a forward body end to a nose end. When a loop from a lariat is passed over the head and pulled rearwardly, the body will respond by rocking rearwardly. As the body rocks rearwardly, the head moves from a forward position to a rearward position wherein the nose end points rearward and the body rides on the upright skids. The loop is then released as it slides rearwardly over the tapered head. Once the loop has been released, a continued forward pulling force against the body will rock the body back into a normal position.
