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. Jim
