NEC V 20
WDC90C00 -JK
Just like my other V20 but runs at a faster pace. This 8MHz V20 is fitted onto a Juko ST "TurboXT" motherboard that runs it at 12MHz. It's a late 8088-based motherboard and has been manufactured a year after the 486 made its debut.
In West-Europe not many TurboXT like these have been sold which makes it a somewhat rare piece.
Performance wise it runs just a little better than the normal 8MHz version. See the benchmarks below:
Standard 4,77MHz 8088 : 8 points
Standard 8MHz 8088 : 16 points
NEC V20 8MHz : 22 points
NEC V20 12MHz : 27 points
By far three times faster than the original IBM XT and noticeably faster than the standard 8088 at 8MHz. It's a nice motherboard to build an XT-class system that has that speedy edge available but can also run at the original 4.77MHz when the turbo-mode is disabled (which can be done on-the-fly). This way you can run speed sensitive games as well.
