I recall a board like that that a friend of mine had - he brought it
over once and we played with it.  If I saw a picture of a Petunia, I
might recognize it - it had a distinctive appearance (it mounted
parallel to the back of the PET and provided pass-through connectors
at the top of the board.  There was an RCA connector somewhere in the
middle for unamplified (IIRC) audio out.

After a bit of digging, I'm not sure if he had an HUH board or an MTU
board - I tried googling, but all I could find was reviews, no
pictures or manuals.  I did discover that MTU is still in business,
which I found somewhat surprising.
