Steve asks: These were circa early 80's and this board was 4 CP/M systems. I think there were single and double boards too. There were some bizarre hooks between the CP/M BIOS and the Unibus (usually VAX/VMS... but there may have been others) filesystems that I never really grokked. The relationship to VMS printers was more straightforward. But yeah, you need some specialized drivers etc. probably not updated since VMS 3.x to use this. We had these in the 80's and the secretaries would connect to the VAX, then connect to the embedded CP/M system, and edit files using CP/M word processor, then print to printers on the VAX. Pretty convoluted. Later on the same secretaries used an emulated IBM PC inside the VAX. Tim.
