Hi all and thanks for the replies. I bought it a little while ago for £100. It is a good little desk. I run my own desk here at the theatre, but my sister has a small theatre group that performs in other venues. These venues will sometimes not let me use the in house desk. Rather than drag mine out of the control room, I thought I would get another to take with me. The ADB will do fine for that. It all runs fine and I could use it as a backup at the theatre. If I could get another, I could leave one in Essex instead of taking it there from Wales each time. I have no idea what software it is running, but it look like it is running under MSDOS. As long as I can get it all sorted that will be great. It has not got to do anything special, standard rig plus ten or so intels. Thanks. Daniel.
