Trying to bring back this post, I managed to get floppy images to configure the BIOS, figure out the hard disk type and get it to boot to Dos.
I got a CGA adapter coming to display the external output onto a screen, but does anyone have any info on the expansion dock? There's a little slot at the back, that is for a exteranl dock.
I was hoping to see if I can figure out how to mod it to get a adlib in there a SB 1.0/clone

I can't find anything like a pinout, but there's a post here: https://www.reddit.com/r/retrobattlestations/ … couple_friends/

that claims the internal is a mini-ISA:

-An adapter from the internal expansion slot to external ISA slot (which never existed but I always dreamed making one, because slots are just tiny ISA slots) and a ISA network card

So it might be possible to make up an adapter.

That's the lt 286+ too high end for me 😉

I think I found a picture of the unit, but not much else yet.
