LOBO Systems MAX-80

Hi, I was curious if anyone had any information about (or experience with) LOBO Systems MAX-80's. I have four of these, and they came with no accessories, documentation, etc. I found an operations manual and a Technical Reference manual, but that's about it. My only testing so far was to connect them to an NTSC monitor, and all I get is some static-like display. Reading the operation manuals, it says something to the extent that it should display static if there are no disk drives attached. But another part of the manual says it should show some text on power-on. I am hoping to connect a floppy to one of these soon, and try to get it to do something useful -- but I wanted to ping the list to see if anybody has played with one of these, or might have additional documentation. Thanks, Garrett Meiers
