NEC V20 CPU: A bit of pep for an XT

The NEC V20 is a processor that has been used in IBM PC/XT systems, offering a 4.77 MHz clock speed and a 32 KB or 64 KB cache. It is known for its high performance and reliability, with some users praising its ability to handle high demands without overheating. The V20 is often compared to the Intel 8088, which it is compatible with, but it has some advantages such as a higher clock speed and more cache. However, it is not as widely used as the Intel 8088 due to its higher price and limited availability. Some users have reported issues with the V20's compatibility with certain software and hardware, but overall it is considered a reliable and powerful processor.
