By connecting to the ‘Audio out/Lightpen’ port the SAMdac allows standard audio from the SAA1099 or beeper to pass through without having to swap speaker connections.
Produced by Ben Versteeg under the moniker of INNER and originally sold for £25 or 70 Guilders with a 2 month guarantee.
The main application to utilise the SAMdac is the SAM MOD Player.
