Is this what I think it is?

Vortex made their own 486 Bridgeboard-type card. I don't think they did 486 upgrades for the 2386. There was a company here in the States that did, however.

I actually have a kit that upgrades the 2286 to use a 386. Pop the 286 out of its socket, plug the new board into the socket, and voila. The 2286 is already a double-width card with its daughterboard, and this thing makes it ever wider! (it came with risers for the daughterboard)

Vortex's board (http://amiga.resource.cx/exp/goldengate) is distinctly different from the Commodore Bridgeboards. Different PCB, different software. It's "based on" the 2386 only in that it's also a 386 (or 486). Unless you're thinking of a different Vortex board.

This is the 486 version of the 2386: http://www.bigbookofamigahardware.com/bboah/product.aspx?id=331
