The T1 version also had eliminated a gate or something of that sort.  It
does have a slightly different pin-out.  Unfortunately my Rainbows are
packed, so I can't look it up at the moment.

P.S. I do not find anything in my service manual supplement for the
26-3003A/3A/4A on the T1 version.  There may be a supplement for the "B"
version of the CoCo 2.  Unfortunately, I've never seen one and therefore
don't have one.
