For Honeywell mainframes, the maintenance contract required an onsite office for field engineers. In those offices were stored spare parts (mostly for peripheral devices), larger tools such as oscilloscopes, and the repair documentation which took up a lot of space. The CPUs for Honeywell mainframes contained about 80 large circuit boards (about 12" square as I recall) which were too expensive to have a full set of spares on each site. For those, we had several district offices with more extensive parts departments. Field engineers had to carry a small toolkit with them which in addition to traditional tools contained soldering irons and wire-wrap tools.
