Cost

edit

Cost comparisons are very important information for CPU history, as well as tech in general. This kind of information really should be added to articles like this one. For instance, I was reading about the Motorola 68010, 68020, and 68030. I don't recall seeing anything that could put those into perspective, in terms of the most fundamental aspect of market success: the cost/benefit ratio. The pure performance of the part (the benefit) is only one half of how likely something will succeed in the market. Cost is, as I recall, mentioned in some other CPU articles (Z-80, 6502) but is lacking from others, like this one. Cost history is also very useful information for historical perspective. The Motorola 68000, for instance, went from being quite pricy to being quite cheap, due to mass production, more competition, et cetera. My suggestion is to make cost part of the fundamental requirements for tech articles. Everything costs money. Readers of this article, for instance, are likely to wonder how Mattel could afford to use a 16-bit CPU in its game system, even though it used a cost-reduced variant. How did the CPU price compare with the F8/3870 in the Fairchilds and the 6507 in the 2600, the Z-80A in the Coleco, and, ideally, the CPUs in the popular home computers of the time that were used for color gaming (e.g. Atari 8-bit). The cost of production per unit comparison is also important information if anyone can find it. What was the margin, in comparison with competitors'? — Preceding unsigned comment added by 107.77.193.132 (talk) 17:58, 6 November 2018 (UTC)Reply

Not based on PDP-11

See this Answer on Stack Exchange: https://retrocomputing.stackexchange.com/a/21930/585

No. It isn't (based on the PDP-11). It is a far descendant of the PDP-8 - or more exactly, the PDP-X.
