→Generations: Notes on few Panasonic FS-A1 kits based on MSX2/MSX2+
* ''the MSX 1'' is the original 1983 machine, with a 3.58Mhz Z80, an AY 3-8910 sound chip, and a TMS video processor — it offers resolutions up to 256x192 with attribute-based colours, single-colour sprites and no hardware scrolling. This machine primarily differs from contemporaries such as the ColecoVision and Sega SC-3000 only in its sound chip;
* ''the MSX 2'' is a 1985 revision that significantly upgrades the video processor; the maximum resolution is now 512x212, sprites are up to 16 colour, hardware vertical scrolling is available, more normative bitmap and non-attribute-based tile colour modes are offered, and primitive graphics acceleration is available — the video processor can independently perform tasks such as drawing lines and filling rectangles. Unlike the TMS chip in the MSX 1, no other machines use this video processor, so MSX 2 emulation is attempted less often than MSX 1 emulation. Panasonic's '''FS-A1''' (1986), '''FS-A1mkII''' (W/ added keypad) and its Italian counterpart, the '''Toshiba FS-TM1''' were based on this standard;* ''the MSX 2+'' is a minor revision from 1988 that adds hardware support for horizontal scrolling and a few extra colour modes; some 2+ models offer an optional modest speed improvement to the Z80 to 5.37Mhz. Panasonic's '''FS-A1FX''' (1988) and '''FS-A1WX''' (W/ added MSX-MUSIC & a Japanese Word processor), while the '''FS-A1WSX''' (1989) was the last MSX 2+ computer;
* ''the TurboR'' from 1990 offers the R800 processor as an alternative to the Z80, which is an offspring of the Z800, offering Z80 backwards compatibility with significantly increased throughput.
