It never ceases to amaze me how prolific PowerPC/PowerISA was (still is?) in the embedded space
Me too! but now it has this weird "retro" feel when you stumble upon something powered by a PowerPC processor
Agreed. When I was fresh out of university, my first job had me debugging embedded firmware for a device which had both a PowerPC processor as well as an ARM coprocessor. I remember many evenings staring at disassembled instructions in objdump, as well as getting good at endian conversions. This PPC processor was in big-endian and the ARM was little-endian, which is typical for those processor families. We did briefly consider synthesizing one of them to match the other's endianness, but this was deemed to be even more confusing haha
