I do have the old board but i do not have access or a programmer or able to solder soic devices (let alone trust myself to do it). As for it working with the old board i do not actually know because i was never able to actually get it fully setup before the board died. And no i am not auto guiding at all.
For when i go and do my star alignment i do center the stars but because its not tracking at all by the time i enter and go to the next star its off and i have to slew it over to fix it, which is normal, but i'd assume with the position of the star not where it should be it messes up the database? if that makes sense i guess.
Where my setup is its kinda tricky because i dont have any sky viewage from the west to the south so i can really only see North to South. When i hit Yes on begin alignment the mount does not seem to track or move at all. just sits still.
