This episode features Synapse SynFile+, originally released in 1983. There was a second release in 1985 which provided compatability with the XL/XE computers. Synapse was thrown into financial crisis by Atari after Jack Tramiel took over and refused to pay for 40,000 software units that had been shipped. Broderbund software bought Synapse in 1984. As such the 1985 release is sometimes credited as being published by Broderbund/Synapse.
