Installing Your Peritek Graphics Board
2.5.3 High Speed Data Port (HSP)
The output buffers on the User Equipment (UE) should be 74ACT374
(FCT, BCT, and ABT are OK), with 64 mA output drivers terminated with
220/330 resistors on the UE. Input signals (from the graphics board to the
UE) will be conditioned by a hysteresis device such as a 74F14.
See
Section 5.15 for HSP signal functions
