Kinka ROMs front

Kinka ROMs (read-only memory) contained the BIOS firmware for Pippin consoles, based on a specialized version of Apple Computer's Macintosh toolbox firmware.[1]

HardwareEdit

The firmware is stored on 4MB of ROM chips, which are mounted on a small 120-pin board that plugs into a slot on the Pippin motherboard. These are interchangeable between developer and production units. The earliest developer ROMs used flash memory.[2]

HistoryEdit

Pre-release and rev. 1.0 ROM units were identified by a white label with the codename "KINKA".[3] The Pippin platform itself is named after Pippin apples;[4] Hoshi no Kinka is a yellow variety of apple that originates from Aomori, Japan.[5]

One of the last Software Development Kits to be issued by Apple included the Pippin 1.2 ROM Update as a software extension.[2]
