Commodore BridgeBoard 486-25
Impossible you say? Not so, I have one here and it works great! Cyrix 486SRx25/50 cpu installed with heatsink removed (but included, you supply your own heatsink adhesive) so you can see that it is in fact a 486-25 BridgeBoard (A2386SX board with what was at the time the fastest CPU you could install in any CBM Bridgeboard might still be). You'll have to get your own Janus and other disks, I can't find the damn things, or I can provide images of all them on a single CDROM if you'd like.
I wonder if I could get AROS x86 to boot on that?
