Hmmm. I got confused by:

There is the 8600 (aka 11/790) listed as a SBI machine.
There is no reference to the 8700.
The 8800 is listed as:
        Basically an 8550 processor in a bigger box with space for additional
        processors to make it into an 8820 or 8840
The 8550 is listed:
        XMI processor/memory backplane with VAXBI I/O

According to the 8k
VAXen, except the 8600, are pure VAXBI, no XMI. XMI came with the 6k

So I assume the "base" machine is the 8550. In a biger chasiss it is
named 8700 and with a second CPU the 8700 is called 8800?
