I can't say I'm wild about a world where Digital Research won. When they were dominant with CP/M, the tools and documentation were bad to the point where most machines had Z80 processors and DR only provided an 8080 assembler, so you had to DB significant bits of code to get the missing opcodes. Developing RSXs to access bank-switched memory under CP/M 3 could have been so much easier with a few examples and perhaps debugging tools. MS/DOS was just so much easier.

DR-DOS 5 was alright and Viewmax a nice way to manage files and directories.

I remember using a Z80 assembler on a CP/M 1.x machine, way back when. If it wasn't by DRI could it possibly have been (shock, horror) Microsoft??? We did have a Microsoft Fortran compiler, which was crap, but that was mostly down to being floppy disk based.

Not trying to be funny, I used the assembler a lot, but I really can't remember who supplied it.

Oh, just had a thought - this was on Research Machines 380Zs, so perhaps it was Research Machines home-grown one?
