Folks, I rescued one of these from work yesterday, it's the slim desktop model with external drive enclosure. Inside there's a daughterboard with 483-33 processor and co-pro socket. On this daughterboard is a VGA port and rotary selector which either makes the machine work or not. (CMOS error beep code) This is a very multi-position selector, anyone have a book of words that explains what they all mean? Google and MANX have come up blank.
