Mini-Computer Systems--A New Class of General Purpose Computer.
Turnblade, Richard C.
The Mini-Computer is compared with the general purpose computer. On a performance basis the Mini-Computer shows several interesting comparisons with the System 360 computer. The Mini-Computer core cycle, instruction execution speeds, and disc operating speeds are quite similar to the much larger 360-30 and 40 while its magnetic tape speeds are somewhat slower. The most serious comparison discrepancy is the much reduced quantity of magnetic core in the Mini-Computer System. In a cost comparison, the Mini-Computer Processor is notably lower in hardware cost. Comparisons of computer costs and performance capability show that the Mini-Computer System performs every basic computer operation at a substantially lower cost. What is needed is a recognition of real application potential by users and producers and a core efficient software system such as the "Pyramid Interpreter System" in which a compiler is used to generate a "macro" code rather than a machine code. Summarizing the results, not only can a Mini-Computer System perform comparably with present-day business computers, but it can do it at only 10% to 25% of the cost. A tabular comparison is shown which accounts for the core enhancing and speed reducing affects of the Pyramid Interpreter System. (Author/NH)
