OBD1 to OBD2 adaptor - do they work?

[photoghog]

I'm planning a swap on my 77 vw bus to an EJ22.  The only 95 Legacys are 12+ hours from me and I do have a 93 2.2 that is near me on the cheap, so I had planned to go that route.  I've seen OBDi to OBDii adaptors on the cheap but have never found anyone that has direct experience on whether they work.  Has anyone on here?
