Not sure if this should go here, but the founder of AW Software has made a working, accessible interpreter for TRS-80 BASIC (a basic language for a computer that was never accessible, sadly). It comes with several IF and adventure titles, including House of the Seven Gabels (Greg hassit) and Hamurabi (not the hugo game, but the original version). It is only for windows (sadly), but I can put it on dropbox, if you like.
“There are four things that we ought to do with the Word of God – admit it as the Word of God, commit it to our hearts and minds, submit to it, and transmit it to the world.” — William Wilberforce
