"Sheduled to be released in the U.S. in 1983 summertime, the NEC PC-8201 was expected to compete directly with Tandy Model 100. Both machines were very similar, but the NEC could expand its internal RAM memory from 16 KB to 64 KB (only 32 KB for the Model 100).
The 8201's 32 KB ROM contained the operating system, Microsoft BASIC interpreter, a simple text-editing program and a telecommunication program. It could display the full 128 ASCII character set as well as Japanese Katakana characters and 61 user-definable characters.
Nec produced its own range of peripherals for the 8201, like a floppy disc controller (PC-8233) and various floppy drive units, including the most sold 3.5" unit (PC-8031). A video monitor adapter (PC-8240), an acoustic modem and a bar-code reader were also available." (old-computers.com)
