(*) I think the DECdatasystem-570 may have used the
KB11-CM CPU instead
of the more common KB11-C. However, I have not been able to confirm that.
Anyhow, none of the ones I received have KB11-CM boards.
The KB11-CM were the machines used in the 11/74.
They were never sold or released outside of DEC except for some field
trials (I was told).
I had one at DEC Princeton (it replaced an 11/70 running RSTS/E).
The DECdatasystem 570's were the last 11/70's DEC was making in the
1982-3 timeframe. AT&T used up DEC's entire supply of new and refurb
11/70's at the end of life (FCC would've required major work for RF
emissions rules). DEC was offering customers 11/780's with good
prices if they could shake loose a couple of 11/70's. DEC Princeton
was given the not for sale 11/74 cpu in swap.
My big problem is we had no spares and when the 11/74 acted up we
were in deep #$%^& since we suspected the backplane.
