Some moth ago I found one of this old instruments at a flea market, but w/o the system disk. I guess there are some hundred of people still using it.. (hironic) If someone really exist... Please made and send me a disk image (teledisk)
ps last sunday i sustain the temptation to buy an old philips/fluke LA PM3585/PM3580 w/o probe and sw, at home I found also it needs a system disk to work ( why they dont use roms and the floppy only to save thintgs!) .
