XMI is XMI. There were some minor revisions for the VAX9000 (my fault), but they wouldn't effect SimH.
XMI was used in two modes; in the 6000 as a system bus; in the 9000 as an I/O bus (the XMIs hang off an adapter from the system's switch). As an I/O bus, each XMI is mapped into the physical address space. Sort of like Unibus on 780. Note that busses nest; XMI can have XBI to produce BI busses. I don't recall how XMI was used on the 7000. On 23-Feb-18 08:02, Tim Stark wrote: > > Folks, > > > > Does anyone have a copy of EK-7010A-TM VAX 7000/DEC 7000 I/O system > technical manual?
