PiO (JP)
PiO (ピオ) was a multi-format games-oriented magazine published in Japan. It is a spin-off from computer & electronics magazine I/O. This magazine was written for beginners & intermediate users with the general aim of publishing as many programs as possible for the widest possible range of computers. The name PiO is an abbreviated reference to the Z80 processor's Parallel Input/Output interface, where the letter 'p' has a double-meaning that also refers to 'petit' or 'playful' (see editor's notes in issue 2, page 184). Many issues have not been scanned.
The Super Expander programs in this magazine require the Japanese VIC-1211M Super Expander cartridge, available here. They will not work with the VIC-1211A Super Expander.
Japanese VIC-1001 computers have a Katakana character ROM and different keyboard layout (see here). In particular, the pound key (£) is replaced with a yen key (¥). This means that program listings use an inverted yen symbol for Ctrl+3 (red), instead of the normal inverted pound.
