HP-IL device Seal s5801c

[PeterP]

I picked up an HP-IL device on eBay (offering a very low amount and the seller accepting it), however I am not able to find anything out about it, or figure out how to fire it up, play with it.

Attached are some images, anyone having any idea? Push comes to shove, I can strip it for parts (like the IL chip and the HP-IL connectors), but I was thinking its worth while to see if someone can figure something out, or provide directions on e.g. how to power it up and see if it has any commands (unlikely), etc.
