You were doing something wrong then.

I took two used Diablo 31s, aligned them in Boston, shipped them by air
freight to Bejing in October, 1979, unpacked them in front of an audience
of 30 odd Chinese engineers in the Beijung Hotel, powered them, and
checked the alignment.

They gave a perfect eye pattern, and when hooked to the Nova 1200, booted
the Chinese Word Processor we'd built first time, and continued to work
flawlessly both later in Shanghai and after my return to Boston.
