I'm cross posting this from comp.lang.smalltalk because no one there
seemed to know anything about Linn Smart Computing's REKURSIV chip set.

The REKURSIV is a WISC based architecture that enables one to provide the
CPU with an arbitrarily complex instruction set.  Besides this,
it sees the universe as objects, just like an object oriented-language
such as Smalltalk.  I don't want to get into details because I'll
probably screw them up, but if you want to know more, there is an
article in the November 1988 issue of BYTE magazine.

I want to know if anybody has ever seen a REKURSIV based device?
David Harland, in his book _REKURSIV:_Object-Oriented_Computer_Architecture_ 
states that a VME board called HADES is available for Sun workstations,
but has anyone ever used one?

If you have some experience with it, did you have the Smalltalk
instruction set loaded and how fast did it execute Smalltalk programs?

For those unfamilier with Smalltalk, it is usually implemented via a
virtual machine and therefore suffers from relatively slow performance
on things such as numerical computation.  To Smalltalk users, a hardware
Smalltalk machine is a very exciting idea!
