size=2 face=Arial><span style='font-size:10.0pt;font-family:Arial'> boards (Am
I right? Memory is vague on this one). Figure I&#8217;d try something a little
different in the mean time and look at a couple of non-CPU based boards </span></font><font
size=2 face=Wingdings><span style='font-size:10.0pt;font-family:Wingdings'>J</span></font><font
size=2 face=Arial><span style='font-size:10.0pt;font-family:Arial'> I&#8217;ve
got the schems (no manual), so wanted to ask a few general questions. I&#8217;ve
included the pinout that I have below for reference. I believe it to be the
correct one. </span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>1) I&#8217;m guessing that I can just drive the board off of
+5 and gnd and ignore the xformer. Looking at the schems (they are *<b><span
style='font-weight:bold'>very</span></b>* fuzzy in the version I&#8217;m
looking at), that looks to be it. Guess I&#8217;m half thinking aloud here&#8230;</span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>&nbsp;</span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>2) Monitor. I see a composite sync line on the schems, but
note explicitly documented in the wire diagram. But I&#8217;m guessing that you
can just pick a color (or tie all three together) and just run it into a normal
monitor. </span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>3) Antenna? FCC regulation or something? Interesting. &nbsp;&nbsp;</span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>4) Any other &#8220;gotchas&#8221;? I was going to start
playing around with it tonight during MNF. I do have a Pong on hand right now,
so I can also peek inside. Just much easier to run the thing on my bench.</span></font></p>
