VAX4000-705 CPU Card incomplete?

[spiceminer]

Dear all,

I have a cpu card of a recently acquired VAX4000-705A here.
I have not tried to power the machine on yet, still in the process of cleaning everything and ensuring everything will be safe for the first power up.

On the card are four small white plastic standoffs, it looks like there is a daughter board missing?

Or was this a free space for expansions not needed for the machine to run?

Thanks and best regards
Stephan

That was for expansion daughterboards.

Nice to have an L4006-BA KA694 705A CPU for one of the fastest VAX 4000 systems you can have. The best I have are L4006-AA KA692 700A CPU systems.

The 96-pin CDAL1 connector near the backplane connector is for the optional KFDDB DSSI Bus #2 and Bus #3 daughter board. Probably not too likely that any hobby user would ever need more than the standard two DSSI buses.
