Wire Wrapping - power + ground
Almost a shopping question, so am not going to address a possible source for this kind of universal wire-wrap breadboard. The bus under the chips could be ground, while the bus between the chips might be +supply. Note that this example is not wire-wrap but a close cousin. I think it was called "slit-and-wrap".
The breadboard can handle both standard-width chips (0.3" and 0.6"). I might strip all the insulation from a grounded connection, solder it to the adjacent ground bus, then wrap it. This builder appears to have soldered each wire-wrap post to the breadboard - not a good plan unless you must connect other passive components like resistors, capacitors to a post.
