Ultimate who made a Pick system for the Honeywell and Dec processor 
families under
license, used the 2900 bitslices extensivly. 

As a side note, a friend had a company, Hilevel Technology, who made 
trace and rom
simulators, as well as development tools (configurable assembler) for 
people using
the bitslices.

you will see them frequently on Ebay, and they usually are quite cheep.

they are designed to be loaded via an RS232 port from a host, and would 
simulate different
rom sizes.  Some systems had trace units that could be added to trace 
address bus activity,
and provide a disassembled trace.  Also you could buy more boards and 
trace other bus
information if you desired.

we had 16 bit and 32 bit processors for the honeywell.  There were 16 
bit coprocessors
that were used with dec.

The host honeywell system was the DPS/6 or "Level 6" system that ran a 
version of GCOS
when native.  We booted a monitor that ran the ultimate I/O on the level 
6, and booted the
Pick system on the co processor.
