This was a very small computer with 18 bit word and 32 words of memory with up to 128 addition words. It was called an electronic computing calculator and was built into a 'beautiful desk.'The Clary Corporation has kept a low profile since its incorporation in 1940. Its current specialties include products for military and other mission-critical applications. It has no Wikipedia entry. Maybe I've just been reading too much Pynchon recently, but... One never knows, do one?
Object is a small wooden cabinet (not a desk), on top of which are a typebar typewriter (looks like an IBM Executive but not so labelled) and a 10-key adding machine, both seated in shaped cutouts in the top. The adding machine has a number of pilot lights and function knobs and keys. Inside the cabinet at the rear is a metal frame containing an array of sealed circuit modules, and a bank of PC boards with discrete transistor logic. Inside the cabinet at the front left is a frame for a programming plugboard (no plugboards are in evidence).

When a tape snaps, it can be spliced back together. The loss is rarely more than a few hundred megabytes—a bagatelle in information-technology circles. When a terabyte hard disk fails, by contrast, the result is usually that all the data on it are lost. The consequence at CERN, specifically, is that a few hundred megabytes of its 100 petabyte tape repository are lost every year. Of the 50 petabytes of data held on hard disk, however, it loses a few hundred terabytes in the same period.300 TB/yr lost to hard drive failures?!

The new implementation [of the extension mechanism] provides the potential for Awk programs to do anything that can be done from C or C++. The simplest example is an extension that provides
chdir(), so that Awk programs can finally change their working directory!
