  It was my
understanding that the EIS/FIS chip is only usable with
the 11/03 (11/2, PDT) machines (and the PDT requires the dual microm
in order to make space for it). 
 Sorry to correct you, but EIS/FIS is an option to the F-11 uprocessor, hence

No, Megan is correct.  EIS/FIS is an option (a single 40-pin MICROM IC
called a KEV11) on the 11/03 KD11 processors.  The relevant instructions
are built-in on the 11/23 and 11/24 KDF11 processors.  The options for the
KDF11 are KEF11-BB CIS (dual-width), DC304 MMU chip, and KEF11-AA floating
point.
