Does anybody have any hands-on (or otherwise) experience with
the Astronautics ZS-1 superminicomputer?

It is a 45 MIPS (which?), 22.5 MFLOPS pipelined (nonvector) machine
with 32-256 MB of real memory(16-way interleaved) and support for
4GB virtual one(64KB page).  

OS is modified 4.3BSD with NFS.  

Bus: Multibus I with up to 32 I/O processors, running Artos, a real time
I/O kernel in addition to the regular CPU BSD kernel. 

Disk striping through virtual drives.  Aggregate bandwiths to peripherals is
45MB/s. 

64-bit word size (supports 32 also).


Some people here at UWM wonder what it is like , so send your
comments, experiences, flames, etc. by e-mail to me and I'll
summarize if there is any interest.

Tnx.
