From Dora to DoS: playtime gets real
PalmOS on FisherPrice Pixter Toy
Kid’s toy runs PalmOS: nostalgia explodes, plus a wild Linux scare
TLDR: A developer made PalmOS run on a Fisher-Price Pixter toy using a clever boot trick and extra memory. Comments erupted with praise, nostalgia, and a surprising side debate about a two-instruction Linux crash, turning a cute retro hack into a lively mix of genius, overkill, and security jitters.
Remember PalmOS, the ’90s/2000s organizer software? Someone just booted it on a Fisher-Price Pixter — a kids’ drawing tablet from the early 2000s — by crafting a tiny cartridge header that tricks the toy into loading a PalmOS image. They even emulated the device and added extra memory because the original had too little. The toy’s 160×160 color screen and tap-ready touch panel make it a surprisingly perfect fit. The crowd went full nostalgia: “mad genius,” “amazing work,” and “I’ve been reading for years” pile up as fans cheer this playful resurrection.
Then the thread takes a spicy detour: a security-flavored hot take claims that, on certain old ARM Linux setups (legacy app binary interfaces — OABI vs EABI, basically how programs talk to the system), a two-instruction program could “simply crash the kernel.” Cue jokes about turning a kid’s tablet into a crash test dummy and meme-ready lines like “my first kernel panic.” Meanwhile, a former Fisher-Price intern spills tea about grinding through Dora the Explorer QA and burning new builds overnight, adding corporate-toy lore. The mini-drama splits the crowd: some call it artful retro-computing, others call it gloriously unnecessary. Either way, the comments are the main event, blending childhood memories, engineering flexes, and security scare-mongering into one deliciously chaotic thread.
Key Points
- •Later-generation Pixter devices (“Color” and “Multimedia”) have 160×160 color displays and an ARM-based Sharp LH75411 SoC, making them viable for running PalmOS.
- •The cartridge slot exposes the full memory bus with two chip-select lines, allowing attachment of ROM and RAM; the first maps a 16-bit ROM at PA 0x48000000.
- •A minimal boot header (magic, version, VM instruction, address fields) enables the Pixter OS to load a PalmOS ROM, with code switching to ARM mode and jumping to ROM at offset 0x30.
- •Pixter Color’s 128 KB RAM is insufficient for PalmOS; additional RAM is added via the second chip-select, while Pixter Multimedia’s 4 MB SDRAM is sufficient.
- •Development leveraged a Pixter Color emulator and a custom board (1 MB NOR flash plus RAM) built by JLC, though some device design choices complicated bring-up.
