Microprofessor II
The Microprofessor II (MPF II), which came on the market in 1982, was a home computer from Multitech (today Acer ). It was the company's second computer after Microprofessor I and one of the first Apple clones , as it was largely identical to the Apple II . The operating system was Chinese BASIC , a BASIC variant identical to Applesoft BASIC that had a Chinese localization. In addition, devices were also sold in other countries that were delivered with nationally appropriate localizations; in Germany the device was sold in 1984 at a price of DM 1,200.

Differences to Apple II
The MPF II differed slightly from the Apple II:
The MPF II did not offer the text mode of the Apple II. Instead, each letter was generated by software and not, as with the Apple II, by the hardware. This was necessary because it was the only cost-effective way to display Chinese text characters on the computer. With a hardware solution, the device would no longer have been inexpensive to manufacture.
Like the Apple II, the MPF II had two graphics buffers . However, the second buffer of the MPF II started at address 0xA000, whereas the corresponding buffer of the Apple II started at address 0x4000.
