These 8x keyboards are all labelled and in the keyboard bin (near sewing corner); all require a proprietary (and possibly specific?) wireless dongle; none are BT or wired. If you know of these dongles, I’d recommend offering some sort of matchmaking be done, otherwise they’re tech junk. And seriously mfgs, can we please have open standards instead of weird losable usb nothings?
I invite the surplus or tidy space or whomever is capable of saying byeeeee! to say it loud!
