Oscilloscope doubles as a serial terminal

I've had some Wyse terms before that sucked, and I've unsuccessfully bid on eBay for ADM-3A terminals before, but I kind of ran out of steam on pure-hardware terminals when I discovered that GNU Screen can open character devices directly!
I only need to get a serial console on something a few times a year, but when I do I really need it to work, whether I'm getting console on a network device, an embedded ultrasound machine, or a case full of modems I'm hacking. GNU Screen satisfies that need perfectly, especially since I'm always working in it already.
I like the idea of the Apple IIc terminal because it combines the warm fuzzies of ancient greenscreen hardware with the not-sucking-ass of a pure-software terminal emulator implementation. That it's cute and diminutive is a bonus.
