This all seems pretty primitive for late 80s. Already in the early 80s I had an Osborne and Walt Bilofsky's (sp?) C compiler. I already could write and compile C programs from floppy with just a few disk swaps, into native 8080. RB-trees, Btrees on disk (floppies), etc. Not all that primitive. In some areas, pretty much the same as today.
