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. -ethan Message was sent through the cbm-hackers mailing listReceived on 2009-12-29 15:00:03
