Wow! WD created the QBUS? Fascinating. I wonder if DEC
made any changes
to the QBUS between the original demo WD boards and the first DEC ones?
Are there any documents about the WD original still extant, do you know?
Which reminds me: I heard a story that DEC did not implement the Unibus as
specified, in order to lock out 3rd-party vendors; apparently the timing
was not quite right. You couldn't complain to DEC because it was not
their gear, and you couldn't complain to the vendor because they followed
the spec...
