I had an Amstrad from mid 80s (cannot remember the model number). It had two 5 1/4 floppies and no hard drive at all. You ran the OS in one floppy drive and the application in the other. Then, there was some specified media swap required to save your work on a third disc. This machine had an 8088 processor and Microsoft DOS 3. I remember that I also had a 9 pin dot matrix printer attached to the computer.
