Fixturing the Video Board Interface
7.13.
Table 7-2 maps the pin and signal names of the Video Board
with the pins of the Vector Output I/O Module.
The fixturing between the Vector Output I/O Module and the
Video Board is minimal. To keep line lengths as short as pos-
sible and to keep interfacing easy, the Y9100A-102 Card Edge
Interface Module is recommended. Most lines from the card
edge interface module to the video 64-pin DIN connector go di-
rectly from the module to the connector except for the following:
•
VDTACK, VWAIT
To synchronize the bus cycles with the UUT, DTACK must
be applied to the WAIT input on the module. There are two
separate signals from the video board; VDTACK (a one
wait-state DTACK from the controller) and VWAIT (a
three wait-state DTACK from the video RAM). Both of
these lines are connected to the inputs of a 74LS08 AND
