The PC-8001 mk2 replaced the [PC-8001](/museum/nec-pc-8001/).

In 1983, the PC-8001 still had great success in Japanese market. However, a lot of competitive PCs were released by other companies.\
PC-8001 had a tough race in business market because of poor graphics feature that cannot display KANJI characters.

NEC had to solve 3 difficult problems simultaneously:\
1\. high-resolution graphics for business users,\
2\. Middle-level (suitable for CPU power) Color graphics for hobby users,\
3\. Hardware/Software compatibility with the PC-8001.

The PC-8001mkII was the answer. This machine was born with expectation and attention. The PC-hobby magazine publishers delayed printing to write detailed information of this machine. However, the expectaition of people changed to disappointment. Most competitive machine already had 640x200 8 color graphics but the PC-8001mkII only had black&white. A lot of hobby-users started to put money aside for the [PC-8801](/museum/nec-pc-8801/) instead of purchasing the PC-8001mkII.

This machine met a limited success, even though NEC had 40,000 back-orders. The PC-8001 was sold over 120,000 within 2 years.

Thanks to **Nomura Hisayuki** for this information.
