Gosh it's fun reminiscing about Modcomp. Now a bit about their accounting. Modcomp calculated their financial position each quarter. As a result, they were hyper about shipping as many mini-computers as they could, before the end of each quarter. Before a machine could be shipped, it had to pass their own quality tests.
We learned that we should ONLY allow Modcomp to ship a machine to us during the second month of a quarter. In the third month, they would ship ANYTHING if you let them. If you took delivery during the first month of a quarter, you got a machine so sick that they had been unable to ship it in the third month of the previous quarter.
