I figured this is as good a place as any to place this, since people here are more likely to have experience with it.
Where do you store your spare EPROMs? I have an MVS BIOS chip lying around; it's been on my bookshelf for 9 months or so, pins up. Obviously, I'm a little worried about something getting set on it, or it falling and getting stepped on, or some other disaster befalling it. Besides sticking it in a small matchbox, what's the best solution?
