From https://en.wikipedia.org/wiki/Model_M_keyboard :
"Some PS/2-to-USB adapters are unreliable with early Model M's that require more power than the adapters can provide."
*sighs* I've used this heckin' awesome keyboard for about twenty years. Maybe it's time to move on, to replace it.
I'm not getting rid of it, though. It goes in the closet along with my Speak&Spell and my TI-99/4A. There aren't many objects I didn't make myself that have quite this much _me_ in their stories, you know?
@ElectricKeet We can put it with the other relics. It's okay to have them. I certainly do.
