The hardrive in my duo was making lots of noise. I swapped in my last extra 320mb 2.5 scsi drive. Newer(1994??) faster and much quieter. I have been looking at the CF/adapter idea. It would make the duo even lighter. Early duo's usually have from 80-240mb. I have a couple of 256mb CF cards handy. Just need the adapter. Has anyone done this with a duo?? I was thinking that it would be of use to any of the scsi laptops. If something went(Video-motherboard-ect.) the card and adapter would go into another vintage laptop. The card and adapter should last for years. No moving parts!!
