Anyone seen these before? Seller Aberco

Yeah, Aberco is also known as Silicon Insider. You can find their Tindie store over at https://www.tindie.com/stores/siliconinsider

I've personally purchased their VRAM (used in a Quadra 700), 30-pin DRAM, FPU card for Classic II and MacBatt battery holder. They're the real deal.
