The 1980's was an interesting decade for computers. In the first half, every brand was a unique piece of hardware running almost unique operating systems.
I enjoyed using all the different flavours of technology that were around. It was an exciting time. However in the second half MS-DOS (Microsoft Disk Operating System) started to become a standard. This was unfortunate in some respects because it was not the best available at the time.
Now there are only really 3 flavours. 10 points to anyone who can name them.
