.i.VGA connector;.i.flat-panel display;Three of the pins depend on whether the
flat-panel .i.jumpers; are installed or not. If the three jumpers are not
installed, pins 11, 12, and 15 are unconnected, as in a normal VGA connector.
If the jumpers are installed, the three pins contain the following TTL output
signals:
P0 Low-order bit (bit 0) of the digital video inputs to the EPC-2's
.i.digital-to-analog converter; (.i.DAC;).
P1 Bit 1 of the digital video inputs to the EPC-2's DAC.
F1 Logical AND of DCLK and -BLANK, where DCLK is the .i.dot clock; to the DAC
and -BLANK is the alternate blanking signal to the DAC. F1 is therefore a dot
clock that is exactly 640 clocks per horizontal display line.
These three signals plus the horizontal and vertical sync signals needed for
flat-panel displays are TTL outputs. F1 is driven from a 16V8 GAL and the other
four are driven from a 74ALS244.
To use the .i.Fujitsu FPF8060;HRUK .i.plasma display;, a custom cable is needed
making the following connections between the display and the EPC-2's VGA
connector.

.i.monitor problems;If you are using a normal VGA .i.monitor;, you should not
install the three flat-panel jumpers. Doing so could create fuzziness or
synchronization problems with some types of VGA monitors.
