This SBC is a Boser HS486H ver:C8 The HS designation refers to Half Size according to Boser.
It came out of an Abbott laboratory analyzer- Cel-Dyn500. No doubt the reason I haven't found any info on it is because its an OEM built for Abbott.
I am trying to figure out how to utilize this SBC as it has an ISA bus connector, but may be able to run as a stand alone SBC if I can figure out the power connector. It orginally was connected to a powered backplane through the ISA slot with a secondary ISA video card with a touch screen LCD panel for video output. I will post pics for reference.
