Editing Motorola 68020 (section)

===68000 and 68010===
At the time the [[Motorola 68000]] was designed, Motorola's design and fabrication services were outdated. Although even small companies like [[MOS Technology]] and [[Zilog]] had moved on to silicon gate [[depletion mode]] [[NMOS logic]] on ever-larger [[semiconductor wafer|wafers]], Motorola was still using metal gates and enhancement mode and their largest fab worked on 4-inch wafers long after most lines had moved to 5-inch. Although the 68000 met the goal of being the fastest CPU available when it was introduced, it was not nearly as powerful as it could be if it had been designed with more modern techniques.{{sfn|Oral|2007|pp=9-11}}

During the period of the 68000 design, the company was working with [[Hitachi]] on their process technology and as part of this they opened a new fab, MOS-8, using 5-inch wafers and the latest [[HMOS]] process licensed from [[Intel]]. This line was capable of building all of the new techniques, but the 68000 went ahead with the older design as they were sure it would work. Moving to new design techniques would wait until the design was in the market.{{sfn|Oral|2007|p=10}} The conversion to the new design techniques took place during the [[Motorola 68010]] effort, a relatively minor upgrade to the original design that added basic [[virtual memory]] support for the emerging [[Unix workstation]] market.{{sfn|Oral|2007|p=20}}
