That machine is a 6152 (the standard RT models are 6150 for the floor standing
version and 6151 for the desktop).  I should have mentioned it in my original
posting.  It uses a reworked version of the APC (Advanced Processor Card) that
is used in the RT models 115 and 125.  It is somewhat slower than those models,
but I can't find the clock rate in the literature on the 6152.

Anyway, that is not the RT follow on machine currently being developed here.
