   Yes NCR does have the NCR-32 chip set which is externally microprogrammable.
   It has been in production for more than a year.  It is used in the NCR 9300
   system as an emulator.  There is also(I think) a FORTH machine based on the
   9300 available which makes the power of the microprogramming available.  The
   chip set is available externally from the NCR microelectronics division and 
   is the cpu for at least one new unix-based CAD system.  The current chips
   run at 8mhz and I'm not aware of any bug list in the basic chip set.  The
   micro-instructions execute in one or two cycles depending on whether they
   have a trailing literal.  The basic chips are the Central Processor Chip and
   the Adress Translation Chip; There is also an Extended Arithmetic Chip which
   is not at full speed yet.

   If anyone wants more info or a contact point to the microelectronics
   division send mail to me.
