Here is a picture of the machine itself, showing the OS/2-based Support Element (an integrated PC that manages the mainframe processor and provides a console for the mainframe OS) and a 3490E tape drive:

Here is a picture of the disk array on the bottom and a network processor on the top; the disk array is an IBM 3390 equivalent (served by a RAID array within that server), and the network processor is an IBM 3172 that provides three Ethernet interfaces:

Here is a picture of an IBM 3174-21L terminal controller, showing status code 3174 (normal operation) and a lit "data transfer" LED:

Here is a picture of the back of that 3174, showing the thick blue channel cables that connect it to the mainframe, as well as coax baluns that permit connection to terminals using Ethernet cables/phone cables/ISDN cables/T1 cables:

Here are some IBM 3178 terminals, connected to the 3174:

Here is an IBM 3287 printer, also connected to the 3174:

The various mainframe device interconnect cables (original bus-and-tag, System/390 Parallel Enterprise Server shrunk B&T, System/390 Multiprise 3000 further-shrunk B&T, duplex ESCON, and LC-connector FICON):

Typing on a 3178 keyboard:

The back of those 3178s, showing the coax balun:

A cartridge tape holder, specifically one I leave on a cabinet that holds EVIEVM's backup tapes:

Detail of a 3480 (1984) and 3490E (1991) tape cartridge:

The back of the mainframe, showing various parallel and fiber channels, Ethernet cables, power cables, and the Support Element console connection:

The front of the mainframe, door shut:

The front of the mainframe, door open; the left disk array is controlled directly by the System/390 processor and the right disk array is controlled by the OS/2 Support Element:

The ports on the back of the auxiliary disk array, showing the famous Bustech 3390 ESCON card:

The interior of that auxiliary disk array, showing a pretty typical IBM x86 server from the vintage EVIEVM is from (the two rack servers in the background handle TLS offload and SNA routing/remote login):

That's all, folks! Check back later for more pictures!!
