Re: TPI 747

Since your running a TBI might just use a 749 wired up as the Sunbird
version, which uses P+H, the info is out on the VSS stuff.   Then use a 730
or 749 memcal (just need right cyl count).  Ludis has done all the work for
ID'ing the cross overs in the I/O stuff so using either prom editor should
make it easier.

   Of course like Ward said, P6 would be nice....
