2 14M 14 MHz clock sigal

3 SYNC Horizontal and vertical sync

4 SEGB Vertical counter signal from IOU, or lo-res indication

5 1VSOUND Sound output (one volt peak-to-peak)

6 LDPS Video shift load enable

7 WNDW Active area display blanking

8 +12V +12 volts DC

9 PRAS RAM row address strobe

10 GR Graphics mode enable

11 SEROUT Serialized character generator output

12 NTSC Composite NTSC video output

13 GND Ground reference

14 VIDD7 Bit 7 of video shift latch (for hires mode colour shifting)

15 CREF Colour reference timing signal

These come from the IIc Technical Reference, both first and second

editions.

It is odd that your listing for the IIc is correct for some of the

signals, but has RGB outputs in place of the IIc's timing signals.

You cannot connect a monitor directly to the IIc video port (with the

possible exception of the the LCD display, or an NTSC monitor). An

adaptor is required to generate the appropriate video signals for an

RGB monitor.
