Over on Aminet there's a schematic for a single slot Zorro II adapter. It's pretty simple, just one chip, if I recall correctly. I used a commercial version of it on my 1000 which has the same sort of slot as the 500.
I built that adapter for my A500 and plugged in a A2091 card. Worked great and ran a BBS for serveral years back in the early 90's. I probably still have the adapter here some where. Technically simple but I recall it did require a lot of wire soldering. No problem if you're handy with an iron, challenge if you're not.
BTW, I also recall the connectors required were the toughest issue. I couldn't find the right size cheap enough to make me happy so I hacked some connectors out of some old equipment and made them work. Maybe connectors are easier to find these days or maybe someone got a hacked up 2000 that could donate at least the zorro connector.
