The National FS-4600F is a MSX2 with 2 cartridge slots (in parallel one at the top). The CPU is a Z80 from Zilog (Z084C0004PSC). The MSX-Engine comes from Yamaha (S1985).

The integrated Word-pro software is version 3, which only provides minor improvements. The printer supports paper sizes up to B4. National also released a add-on cartridge, the FS-SR023 which allows the built-in word processor to print a 48 dot "Brush" style typeface.

While the machine provides the JIS1 and JIS2 Kanji ROMs, it does not provide the Kanji BASIC extensions.
