I'm getting close to off-topic, but it (1) is > 10 yrs old and (2) contains a computer... :-) Does anyone have any idea what the diskette format is? It's not DSDD 512 byte sectors, eg. dd won't read it on a linux box. Luckily the analyzer's OS has a disk-dup feature, so I can make copies, but it would be nice to archive a copy. (On a related note, if anyone has a PDF of the users manual I'd appreciate it... I bought this used for the University, I figured out most of the big chunks but a manual would sure be handy. I have the Maintenance manual, which tells you how to unpack it and shows all the various interesting flavors of power cord.)
