A view inside the machine.
If I didn't miscount, then one can see 172 R-modules. That are logic-
modules with a complexity comparable to simple integrated TTL-circuits:
For example four 2-input NANDs or two flip-flops.
The 35 white modules are mostly drivers and interface circuits.
The two green quad-modules belong to the core which is located between
Six empty slots at the left side are for the I/O bus. The extension box
which contains the peripheral interfaces, for example the TTY interface
is connected with cables to these slots.
