Here's a picture of the left end of the computer shelving as it now looks...
The interesting (and/or wrong and/or evil) part is what's on the screen of the Apple //e:
That's a real master console display from a real copy of MVS 3.8, running on Hercules on the Power Mac G5. (A larger version may be found here.) Needless to say, that's not what one would expect to find on an Apple //e's monitor...
Here's a picture of the TSO user session, on a real 3270 right above it:
As before, a larger version is also available.
The Apple is connected to a 3174 terminal controller with an Asynchronous Emulation Adapter. This feature allows an async ASCII terminal to look like a real 3270. The Apple is running Kermit-65 and emulating a VT-100. The 3174 provides a TN3270 network connection over a Token Ring LAN, which is gatewayed to the house network through a Linux box set up as a router (among other things). Interestingly, the Apple drops characters badly at 2400 baud and higher - unless it's running 3270 mode, where it doesn't have to spend lots of time scrolling the screen.
Old mainframers, especially, will run screaming when they see these pictures.
