/get a rē(-ə)l kəm-ˈpyü-tər!/
imp. Typical hacker response to news that somebody is having trouble getting work done on a system that (a) is single-tasking, (b) has no hard disk, or (c) has an address space smaller than 4 megabytes. This is as of mid-1991; note that the threshold for 'real computer' rises with time, and it may well be (for example) that machines with character-only displays will be generally considered 'unreal' in a few years (GLS points out that they already are in some circles).
See essentials, bitty box and toy.
