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]

Contents

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

Japan

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

France

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

United Kingdom

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

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

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

Character set

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