Since it appears to be retrocomputing day on HN, I thought I'd post my pet project. It's a collection of modern peripherals for retrocomputers. I started collecting a list of upgrades for my ideal dream Mac SE/30 and grew from there. The site is currently mostly focused on Apple II and Mac stuff since that's what I grew up with.
This is pretty awesome! I've got 2 Amigas and 2 Spectrums. They are kitted up and upgraded but this never really ends. This will be useful!
