Guys,

Do any of you know where I could get hold of DG document(s) describing the
microcode of their Eclipse family. It was wide yellow manual with brown
plastic ring binding. It brings back happy but foggy memories.

"The Soul of the New Machine"(book) tells me that the instruction set was
built from the microcode by some genius overnight. Probably an urban myth!
Who knows.

Many thanks,

peter
