What's most amazing to me is that this got so much press. Maybe OS X is ridiculously hard to set up, but I've been doing this on and off with my own VT 220 for the last 5 years on Linux. It's just... not that big of a deal. It's not archaeology, it's just pointing getty at /dev/ttyS0.
I've done it with an ADM-3A from the 70s too, it's just. Not. That. Tough.

- derleth 14y agoOn the hardware level, does the VT 220 connect via a standard nine-pin serial port?
- jff 14y agoIt has a 25-pin serial port which converts to a 9-pin serial port by a simple passive converter (basically, just ditch 16 of the pins and route the others properly, you can actually do serial with just two wires). Same goes for the ADM-3a
- jasomill 14y agoIIRC, while the VT-220 had both 9-pin and 25-pin RS-232 ports, the 9-pin port was used to attach a printer. You also typically need a "null modem" adapter or cable to connect a terminal directly to a PC serial port (or USB serial adapter). There's lots of original documentation for DEC VT series terminals here[1]. [1] http://www.vt100.net/ http://www.vt100.net/
- kps 14y ago"standard nine-pin serial port" Them's fightin' words, boy. DEC had a DE9 serial port connector whose pinout is not the same as the later IBM PC DE9 serial ports.
