HP logic analyser questions

Hi all, Does anyone here own or use a HP 1650B (or 1651B) logic analyser? Do they need DSDD 3.5" disks or can they accept DSHDs as well? I ask because someone has just offered me a HP 1650B - system disk, a few pods and a 1650B analyser - but doesn't have any manuals or know what type of disk it needs. I'm guessing DSDD-only, given that the system disk is supposedly DSDD. Is it possible to duplicate the operating system boot disk using standard hardware (i.e. a PC or my RISC PC)? Anyone got PDF versions of the Operator's Manual, Service Manual and/or Programming Manual? Sorry for the OT-ness of this message - sure, it's not a computer, but it meets the 10-year-rule - the power-on selftest screen displays "COPYRIGHT 1987", so that would make the firmware, what, 16 years old?
