PS/55 (ぴーえすごーごー, personal system /55, Personal System/55) is the series of the personal computer of the Japanese specifications that IBM JAPAN released from 1987.

It is a succeeding product of multi-station 5550 of Japanese original specifications, but is PC/AT compatibles in a wide sense because PS/55 was equipped with a Japanese indication function to a base in PS/2. An MCA model for business was the center, but the AT bus (ISA) model for individuals appeared mainly in the latter half, too.

Name

As for the official name, "personal system /55" (Personal System/55), the abbreviated designation are "PS/55".

"The PS" inherited "55" than "multi-station 5550" of conventional Japanese specifications by naming (ES/9000 of the mainframe, AS/400 of the midrange, RS/6000 of the UNIX, PS/2 of the personal system) of IBM at the time like PS/2.

Summary

IBM released IBM PC family (ancestor IBM PC, PC/XT, PC/AT) worldwide, but because Japanese indication was necessary, these did not release it in Japan and released "the multi-station 5550 series" of Japanese original specifications instead.

PS/55 came up as succession of 5550 series, but it was PS/2, and the bass was equipped with Japan's original display adapter or keyboard.

I classify it roughly into PS/55 (wide sense), and there are the following product systems and can distinguish it by a model name (because 5551-S09 is S e.g. PS/2 system).

  • Old 5550 system (model A - P)
  • PS/2 system (PS/55 of the narrow sense is not a compatible machine of former 5550 after model S)

The old 5550 school changed a name of a product of the architecture of multi-station 5550 to "personal system /55" (PS/55) and did 併売. Therefore, the architecture is totally different from the PS/2 system, and most of the software (the OS, applications software) compatibility does not have the hardware (expansion card, display, printer), too. The details of our model refer to multi-station 5550

The PS/2 system is a PS/2-based Japanese specification; of PS/2 and hardware and software is compatible. 5571-S of the standard lamp model announced in May, 1987 was spent sequentially than a high-ranking model first and rearranged an old 5550 system progressively. It was only an MCA model for business at first, but, besides, the AT bus (ISA) models came up the PS/55z series for individuals in the latter half, too.

In addition, because needs was to the PC of English letter specifications, "IBM PC convertible" released "personal system /2" (PS/2) in April, 1987 in "5160 personal computers" (PC/XT) and "5170 personal computers" (PC/AT), July, 1986 in November, 1985 when IBM JAPAN released old 5550 and developed a wide product in conjunction with the PC of Japan specifications [3].

I explain the model (after model S) of the PS/2 system in the following.

Characteristic

The following characteristics were given for a Japanese market.

Display adapter

 
Display adapter II

The text screen supports Japanese indication at a hardware level using kanji ROM by 1066x725 dot (24 dot font, 41 columns of 25) eight colors indication from old 5550 sequentially. The graphic screen is 16 colors of 1024x768 dots. This is resolution same as later XGA, but there is not the compatibility. The hardware which took these functions was gathered as "display adapter" (I say the display unit adapter) by an MCA card, and it was equipped by default by a system device.

"Display adapter II" which improved this point was carried first by model 5550-S because the display adapter of released model 5570-S was incompatible with VGA of PS/2. As for this, VGA on the motherboard becomes effective at the time of the power supply injection, and I get, and the video signal is output by a display adapter. I invalidate VGA with the Japanese mode and am replaced by a display adapter using same VGA in English mode of J-DOS and later DOS/V. In addition, I supported 1024x768 dot 256 of 262,144 colors indication newly.

 
XGA-2 indication adapter /A

XGA like PS/2, the XGA-2 deployment model appeared late in the series, too.

JIS sequence keyboard

 
5576-002 type keyboard

The JIS keyboard which assumed the following a representative was prepared by separate sale and was able to put it together with the main body freely.

  • Sequence same as a type 1 keyboard of 5576-001-5550. Scan cord set 1 of the PC/XT equivalency is nonimplement.
  • 101 extended keyboard of last part of 5576-002 - PC/AT and PS/2 is Japanized by a basis. The kanji key is Shift+ left Alt.
  • The space-saving keyboard which omitted a numeric keypad from 5576-003 - 5576-002.
  • I commonized operability with 101 extended keyboard to a base in 5576-A01- 5576-002 more. The kanji key is Alt+ half size / full size. I was announced as OADG standard keyboard [4].

I make efforts in a model mounted with an MCA bus and it

A model mounted with the AT bus which succeeded PC/AT at the time of the first announcement was performed a lineup of in PS/2, but the lower model succeeded 5550 hardware in PS/55, and, as for the high-ranking model, an MCA bus deployment model was performed a lineup only of for a while. I add the AT bus model later.

Japanese-adaptive of the OS

The following OS's were prepared for.

  • IBM Japanese DOS K3.x (popular name kanji DOS sells the English environment of the PS/2 compatibility as PC DOS of the other product only with Japanese mode.)
  • IBM DOS J4.0, J5.0 (popular name JDOS includes the English mode.)
  • IBM DOS J4.0/V, J5.0/V, PC DOS J6.1/V, J6.3/V, J7.0/V (supported popular name DOS/V more from the latter half.)
  • IBM operating system /2 (OS/2)

In addition, the details of PS/2 and the MCA architecture that became the base refer to IBM PS/2

Model

  • Tower type (forerunner of later IBM PC Server 9x)
    • 5570-S/T/V ([5] that only 5570-S equal to the PS/55 first generation machine does not support DOS and OS/2 of the English version a tower of the first half by default because compatibility with PS/2 was not complete.)
    • 5580-Y/W (tower of the latter half)
  • Business desktop (later IBM PC 300, forerunner of the IBM PC 700 series)
    • 5560-W/N (higher desktop)
    • 5550-S/T/V/W/N/Y/L/R (main desktop)
    • 5540-T (lower desktop)
  • Small business, personal business
    • 5530-Z/S/T/U/W (one display version.a forerunner of later PS/V Vision)
      • 5530-Z (I was sold as a product for education markets from Shingaku Sha and was called "PS/55Z 286" "5530-Z 286" when I sang the general thing that I was not sold and was equipped with 80286 and 16 bits MCA, Japanese display adapter and compared it with the.personal computer for education markets of other companies, and "Japanese could display definitely for high-resolution (1024x768)", and 5530-S (popular name "PS/55Z") appeared later.)
      • 5530-S (IBM was called "PS/55Z SX" "5530-ZSX" by failure in a market for Japanese individuals that a market re-entry model for first individuals was equipped with 80386SX and 16 bits MCA, a Japanese display adapter since IBM JX which was over and distinguished it from 5510-Z, and popular name PS/55Z supported DOS/V later.)
    • 5510-Z/S/T (there is not a Japanese display adapter the AT bus deployment exclusive use of DOS/V and OS/2.a forerunner of later PS/V.)
  • Laptop
    • 5545-T (the plasma display deployment)
    • 5535-S (DOS/V came up as the exclusive OS of our model)
  • A4 notebook
    • PS/55note (the forerunner of ThinkPad in the back.an AT bus model and an MCA model)

Competitive product

As well as 5550, the competition was a model for the following domestic business not PC-8800 series and FM-11 for the hobby for the individual.

Influence

  • There was hardly the compatibility with multi-station 5550, but most of 5550 users use only the package software (including DOS document program, 3270 PCs, 5250 PCs, Ichitaro, Multiplan); of data because finished it if was compatible, was able to shift.
  • Before DOS/V appearance, PS/2 keyboard mouse, VGA monitor, 3.5 inches of floppy disks, overseas software spread.

Remarks

  • I succeeded the 1024x768 resolution of PS/55 than 5550, and the resolution is the same as XGA, but there is not the compatibility.
  • The display of PS/55 can display) including the VGA(640x480 resolution with an English mode, but it is in form to receive the signal of the power supply than the main body depending on a model and it is the same to commercial PC/AT compatibles and cannot use it.
  • As for some models of PS/55, it was supplied OEM as "the I series" by RICOH [6].
