> The 3215 was the s/360 console printer keyboard No; the 1052-7 was the console typewriter for various S/360 models. The 3210 and 3215 were console typewriters for low end S/370 models, eventually replaced by special models of the 3270, e.g., 3278-2A, 3279-2C.

Those limitations were removed 40 years ago :) However the speed of zTPF comes from not allowing applications to do things that require expensive services, such as z/OS provides. The 3215 was the s/360 console printer keyboard (much faster than a typewriter -- it had to keep up). z/TPF still supports 3215 protocol via OSA card, but also has 3270 support. The 3215 protocol has some big advantages when its a computer at the other end doing automation, so still popular.
