Maplin 600 Note Sequencer

Unfortunately I didn't take into account the firmware required for the sequencer so it turned out to be an impossible project, now 40 years on and contacted by a kind enthusiast who sent me the binary file it opens the way to building this project..so if anyone wishes to have a go here are the details and the binary file. (click on the leaflet to the left to download the contructional details.)
