It is the compact machine of the design where the SORD M5 was developed in for hobby, is witty. It ties up with the タカラ of the toy manufacturer and as a personal computer you aimed toward the development which exceeds the framework e.g., the software is supplied even from the software manufacturer of the ナムコ and the like, but the MSX of late start furthermore it kept becoming the existence where the shadow is thin gradually with the appearance of the FamilyComputer. It is the M5 which is tossed about result in age, but, the kind of air which is succeeded even in the current machine does the concept of the M5.
As for the basic design of the M5 there is no MSX and compatibility which start late but almost it is identical.
Debut of the M5 being to be October of 1982 is 8 months ago of MSX. The grandchild person of the software bank brought plan to the SORD in other version, it is said the MSX camp (the ASCII west person and the Microsoft, home appliance each company) utilized the concept. (There is also a theory of the opposite)
As for truth you think you do not understand it is not the one which at that time is in industry but.
The funny one sentence was found from the M5-related book of that time.

The circuit of the M5 is gentle. Normally, as for the game machine, way it is not imitated
Purposely changing pin arrangement and/or replacing memory address complicated
It has done, but the M5 when it is imitated even then is good, with the feeling that
It is arranged cleanly. Many people are easy to use even alone the computer
Because, is sawed idea.

From " M5 interface encounter technique " genuine sentence hall new optical corporation " M5 tidbits " reference

Considering also the cost aspect, you think that the circuit is simple as the ことだ, but the last part from at the time of sawed establishment is the idea which is succeeded. It meaning that the kind of air where this has indicated everything does, it does, but.
When (the one which has been known sees stealthily please teaches)

When the hardware is seen, the CPU the Z80 (the 3.58mHz) with is standard of that time. Memory the RAM 4kByte / the ROM 8kByte / is meager even at the VRAM 16kByte and level of that time, but if price (49,800 Yen) with of character of the machine is thought low, it is the helpless place.
As for the ROM of the 8kByte monitor function (only correspondence) with as for the BASIC is supplied to the BIOS of the DOS/V machine with the external cartridge.

The expansion storage * cartridge existed in one for expansion of the RAM, but because the slot of the M5 exists only one, in order to expand memory, expansion box EB-5 (the left photograph) it was necessary to purchase.

The cartridge of the BASIC existed seriously considering the function of the basis functional BASIC-I , sound and the picture which have belonged usually, the BASIC-F and 3 types which seriously considered the BASIC-G and the calculation function which are convenient to game development. (Also the RAM the 4kByte is expanded by the fact that the BASIC cartridge is used)
Furthermore the FALC (productivity package) also the cartridge being prepared, in order to be able to make also business processings simple, it was thought. (Speaking roughly, original form of the chart calculation software of the EXEL and the like)

By the fact that expansion box EB-5 is used it is increased in 3 slots. If the BASIC-G and expansion storage * cartridge EM-5 (the 32KB), floppy disk device FD-5 (3 inch FD drive both sides 320KB) it equips in each slot, it becomes the full specifications machine.


Indicatory ability of the M5 being highest, is sufficient efficiency as for a resolution 256*192 dot 16 color and a hobby, furthermore the video controller which is mounted (the TMS9918A) powerful function such as important sprite was had for the game program. (The TMS9918A is adopted even with many machines after the M5)

The VRAM of the M5 does not exist in the memory space of the CPU, is connected directly to the video controller, furthermore is not the CPU and it has been connected to entire performance rise the VDP (the video controller) by doing drawing processing.

The M5 actualizes also sound function mounting, the private sound generator (the SN76489A), being possible, to use 3 chord + noise 1 sounds simultaneously, in order in the same way as the VDP, to operate without applying load on the CPU, it is designed.

The Lsi for sound differs in the M5 and the MSX. This is said even the for the sake of the YAMAHA has related to the development of the MSX, but the AY-3-8910CA (the MicroChip) the YM2149 of the interchangeable item (the YAMAHA) the Lsi is used for the MSX.


As a feature of appearance the substance of astringent grey keynote and accent of yellow around the slot being exquisite, it is splendid design, weight in the 800g and truth is the light machine with the compact, (however the A/C adapter being large fearfully, it is heavy). Furthermore when you see carefully, becoming 5 rectangularities without the shape umbrella り air of the key top, it increases.

As for the key top of 5 rectangularities there being an intention where the designer who designed the M5 is strong, it is something which it actualizes so it does. The design which does not have compromise at one of charm of the M5 the shank.
Originally hiragana of a certain expectation is not printed in the key top of the machine of the photograph. When having transferring, already it was this state, it is is, when, but the information where this machine is detailed the one which has been known is please teaches.


Is observed it was the company where the SORD corporation which made the M5 is called the Japanese Apple and about the れ る as venture enterprise. Also the possibility of having become the rival of the present Microsoft depending upon when is about was.

The SORD is established by OB several names of the Tohoku University engineering department which begins Shiina 蕘 celebration in March of 1970, as for goal with the computer which at that time is large amount low as a price with who like the portable calculator it was to try to be able to use simply.
Because establishment of the Microsoft April 4th of 1975 (corporate body conversion 1981 year), establishment of the Apple is 1976 years, you understand how the SORD was advanced.
The achievement of the SORD even presently exists familiarly in the chart calculation software of the EXEL and the like, because as for patent of the basic software of chart calculation the SORD corporation had, is.
(Regrettable business of the SORD corporation is sold at Toshiba and presently the SORD corporation does not exist, Shiina of the establishment person presently establishes the professional side corporation and participates)
