- I believe this is incorrect. The 486SX is physically different from
- the 486DX. The 486SX is NOT a 486DX whose coprocessor circuits do not work
- due to some defect and is sold as such.
- This technique however is not uncommon in the industry, especially
- in the case of microcontrollers. Very often, microcontrollers whose logic
- portions do not work can be sold as EPROMs, since microcontrollers, for the
- most part, are logic cores surrounded by a fair amount of memory.
