| Sounds about right to me, but I am interested in the B and C variants? Why
are purdue different and how does this �Vax multiprocess.

| The Purdue variant is a 780 Multiprocessor that uses two CPU's on the same SBI.
They had to hack up the microcode to get it to work (something about running
user-mode code at elevated IPL.) It was done at about the same time as we
announced the 782.
There is support in the �VAX-II for up to 4 processors, but there is no software
support for it (except, I believe, in VAXeln if you build a multiprocessor
version from sources.)

| A few notes:
There are no G floating VAXstation Is. All VAXstation Is are D float. A few
people in DEC have G float MicroVAX Is and put QVSSs on them, but that isn't
really the same thing.
VAXstation 500 series hardly counts as a type. The Tek scope on it is simply
a peripheral -- VAXstation I, II, and II/GPX all require their own SYSLOAxxx,
so they should count.
You forgot the 8300.

| A couple that I know of, in 'one-of' states.
A hardware simulator was used in the early days of VMS to allow testing
to start before real 780 hardware was available. The V1.0 listings had lots
of tests in error paths (bugcheck) to determine if it was on a real VAX
or the simulator. Perhaps someone out there would like to add some detail.
DECwest built a dual processor MicroVAX I and used it for ELN testing.

| I saw the hardware simulator. It was an 11/70 (in part) but
with things bolted on to accelerate VAX instructions. It also had
a 32 bit wide front panel light display, but since it was regarded
as so confidential it had one half labelled "address" and the other
labelled "data". It ran baselevel 3 of VMS. The earlier baselevels
were tested on software simulations on LCG machines.

| Wasn't the thing actually _2_ 11/70's, 1 to interpret instructions and one
to do everything else?

| MILVAX: Militarized VAX. Built by Norden? (Wag)
VAX-11/751: OEM Version of 750. Interesting package.. fits in a
19 inch rack.

192.11 | Multi-KA630 systems | FURILO::KAISER | | Wed Feb 26 1986 08:33 | 6 |
| Digital has at least one OEM customer -- I work with them -- building products
based on multi-KA630 MicroVAX IIs. Their system has a master that runs VMS, and
three slave processors in the same backplane that run VAXELN images. They buy
both systems and boards from us (recently approved).
