ICL set up the Scottish Development Centre at Dalkeith House in late 1970 and transferred all the System 4 software support from Kidsgrove. That would have included the System 4 Cleo compiler that, I suspect, compiled directly into native code; not via intercode. The aim was to free up resources at Kidsgrove so that the people could work on New Range and to provide a centre for software in Scotland that could attract Scots back home to work on software. DME / Leo was developed at Dalkeith.
