Basically, it wasn't possible to contact Mervyn J. Estcourt to ask for permission to release it, so it's never had a physical release. A shame, as I'd like to. I'd also like to make a little update to it, but I lack the time just now. The broken link is down to the fact that I lost my webspace. Howe...

It goes into $2401 (when Dragon DOS is present) or $1E01 normally. The loader then copies that routine to $0C00 and calls $0C08...
