No, but then there weren't many hobbyist boxes using the PPS-8, F100-L, 
PACE, IMP-16, WD16/MCP1600, LP8000, or iAPX-432 either.  The conclusion 
I reach is simply that obscure microprocessors that had a relatively 
poor price/performance ratio saw little hobbyist use.

The IM6100 wasn't nearly as expensive as the 9440, and there was more 
public-domain PDP-8 software than public-domain Nova software.
