The dual-height 11/03 processor allows a CIS as
well. I have a
couple that have that chip. As far as I can determine, both those
machines were used to sort, analyse, and archive incoming raw data.
Are you sure... I don't remember a CIS option for the 11/03. There
was an EIS/FIS option chip which could be used on 11/03, 11/2 and
PDT-11/1x0 systems. But the only CIS option chip I know of works
only on 11/23[+] (and possibly the 11/24?)
