I had an Osborne 1. I had to swap disks multiple times to compile anything. I remember the C compiler by some guy, 'Walt Bolisvki'?, had the arguments passed in reverse on the stack (last on the top) and printf and friends ended up crazy hacks. I didn't have access to a Unix at the time or very limited open source so ident was not a thing.
