The Sanyo PHC-25 is a home computer released in Japan in 1982[1] by the electronics company Sanyo.[10][11] PHC is an acronym for Personal Home Computer.[12]

It is grouped with the lower-end PHC-10 and PHC-20 models[3][12] which were announced at the same time,[3] and with which it shares the same dimensions[8] and styling.

The PHC-25 came with Sanyo Basic v1.3, an eighty instruction BASIC dialect.[10] A few emulators exist for this system.[13][14]

Distribution, marketing and reception

[edit]

Japan

[edit]

The PHC-25 was announced in Japan in mid-1982 with a price of ¥69,800.[1]

France

[edit]

The PHC-25 was announced in the French press alongside the PHC-20 and PHC-8000 in late 1982 for a planned launch in November[2] or December to January[15] at a price of 2200 FF.[2]

There were complaints about the lack of software availability for the PHC-25.[16][17] (In response to one of these, the magazine Votre Ordinateur estimated that there would have been around fifty software cassettes available in France circa early 1984.)[17]

As of January 1984,[Notes 2] Sanyo was still promoting the PHC-25 in France, with "planned extensions" including an 8K RAM expansion and floppy disk drives.[9]

The PHC-28- which launched later that same year- was seen by Votre Ordinateur as a replacement for the PHC-25, noting that its MSX compatibility would be a "guarantee of security for fans of the brand" who had complained about the PHC-25's lack of software.[16]

The PHC-25 was used for some educational courses in France.[18][19]

Cancelled launches

[edit]

United Kingdom

[edit]

It was announced in late 1982 that the PHC-25 would launch in the UK for £150 in January 1983, alongside the PHC-10 and PHC-20.[3]

However, while all three made it as far as being reviewed[20] in Your Computer magazine in October, the same publication later reported that they had "disappeared again in November"[4] and there was no further sign of them on the UK market.

United States

[edit]

The PHC-25 was presented in the US at the 1983 CES[21] with a planned price of $199.[5][6] However, Sanyo later decided against selling the PHC-25 there due to cutthroat price competition in the low-end US computer market at the time.[7]

Technical specifications

[edit]

The PHC-25 had the following technical specifications:[10][22]

  • CPU: NEC D780C @ 4 MHz (compatible Zilog Z80A)[8]
  • Memory: 22 kB total RAM[8] (16 kB user RAM plus 6 kB VRAM),[9] 24K ROM[9]
  • Keyboard: 65 keys,[8] 4 function keys, 4 arrow keys
  • Graphics: Motorola 6847, 16 x 16 / 32 x 16 text; 64 x 48 (8 colors) / 128 x 192 (4 colors) / 256 x 192 (2 colors) graphics
  • Sound: Optional (PSG-01 extension)
  • I/O Ports:

The PCH-25 character generator offered a different character set to the default Motorola 6847 character set:[23]
