Hi I got a Unisys ELI 4663 486 computer the other day. Very good condition.

On the back there are 2 lids and also a extra ISA slot (on the backside of the ISA riser card) but there are no normal brackets to hold a normal PCI/ISA bracket with a screw?

Anyone have any idea what this is? My guess is perhaps a PCMCIA extension or something that could fit if those lids were screwed off? Or maybe some special Unisys network card?

I would love to fill this with something. My first idea is to access a CF to IDE thingy from htat lid. But what was it for as original`?
