Met de Pollution Painter kun je de luchtkwaliteit fotograferen. De Pollution painter is een installatie die bestaat uit een fijnstofmeter en een lichtstok. De fijnstofmeter meet de luchtkwaliteit, en een minicomputer vertaalt deze metingen naar lichtsignalen. Door die lichtsignalen te fotograferen krijg je een beeld van de luchtkwaliteit.
Waag Futurelab bouwde zo’n Pollution Painter tijdens een workshop van het Citizen Science Lab in Leiden. Zij bouwen voort op het werk van de Engelse kunstenaar Robin Price en milieuwetenschapper prof. Francis Pope die de Pollution Painter ontwikkelden.

At first I thought this was a parallel port used for connecting to a printer in another room, but knowing what I know now, I suspect that Brian Leeper (the commenter below) is probably correct that this would have been for connecting a dumb terminal to a minicomputer.
The DDP-116 was introduced in 1965, and was the first computer on the market using a 16 bit word length and arithmetic. With that, this machine was the start for the coming years of a new phenomenon: low cost computing, based on minicomputers.
Rick got a kick out of seeing the first computer he worked on in a display case at a museum -- the PDP-8 minicomputer. Science Museum, London.

1972-4 issue of japanese magazine "president"
featuring articles on teradyne and interview with nick dewolf

translation (via google translate):
It's too short a time to evaluate a person. Two years is necessary. If the person is not suited to Teradyne after two years, they should be fired and encouraged to move to another company, which is a good idea for both the company and the person. Teradyne generally wants aggressive people, but there are also companies that value a stable environment.
There is no labor union. After the company was established, a union came and actively campaigned to form a union, but the employees voted and 85% were against forming a union. DeWolf shrugged his shoulders and said, "If a situation were to arise in which a union were to form at Teradyne, I would have resigned, as I felt that I had not been able to lead it well."
"Love at first sight" with Dorio
After people, the next step was money. DeWolf knew the company would be in the red for some time after it was founded, so raising capital was also a big job. The initial capital needed was $75,000.
DeWolf and D'Arbeloff started by running around among their friends, asking each person to put in $5,000 to $10,000. This was about the same as a secretary's yearly salary, and in some sense wasn't really an investment. "If someone had $100,000, they'd ask him to lend them $5,000. It was only 5% of his money, so if he lost it, it wasn't a big deal to him. That's how they raised money from their friends, and in the blink of an eye, they'd raised $120,000," DeWolf explains, laughing uncontrollably.
He seems to have avoided going to bankers or large organizations for financing, and in any case, he had enough working capital from friends.
When it came time for the second round of financing, they decided to negotiate with a venture capital firm called ADR. DeWolf already knew how ADR invested, and their philosophy of lending money to people, not to balance sheets, suited DeWolf's philosophy. DeWolf said that when he met ADR's president, Dorio, it was "love at first sight." ADR provided him with $100,000.
The company got off to a good start. Its predictions went well and it started to make profits relatively quickly. As a result, financial institutions that had initially said, "What are you doing, young man?" started to lend it money.
At the end of 1970, the number of shares issued was approximately 2.68 million, of which 40% were ADRs.
Together with DeWolf d'Abeloff's holdings, the three parties' total holdings amount to half of the total shares issued.
Speed Kills
Teradyne, along with Fairchild, has grown into a global manufacturer of semiconductor test equipment. Of course, Fairchild is much larger in terms of company size, but Teradyne is unique in that it is a specialized manufacturer of semiconductor testers.
DeWolf has worked in the semiconductor industry for both GE and Transitron, and has firsthand experience of what is needed as a consumer of testers that inspect the performance of semiconductors.
Semiconductors are mass-produced, but because they are so delicate, it is said that 20-40% of products do not function as specified. Therefore, detailed tests are required to check things like leakage, switching speed, and amplification.
The first product that DeWolf made was a small diode tester with only four test items. Over the years, new types of testers were added, and in 1965, Teradyne entered its second growth phase with the development of a new system that combined a minicomputer with a tester for the first time. Apart from its computer-based thinking, Teradyne's distinctive product was a tester called the "Mack-truck."
In the United States, Mack trucks are known for being tough and able to withstand rough use for long periods of time. This is what DeWolfe noticed.
Although we call them testers, we do not make devices that are carefully handled in a laboratory, but devices that are directly connected to the production line in a factory.
There---
Strong and durable for long-term use
Does not require fine adjustment so that even female workers can use it
Circuit boards can be quickly replaced in case of failure
We developed a tester that meets these requirements, and we offer a 10-year warranty on this tester.
DeWolf says, "I like the term "Speed Kills." It was originally used in traffic accidents, to mean that driving too fast is dangerous. I applied this to testers as well. The faster a tester works, the better. Both manufacturers and users need to be aware of the speed.
