Hi Chuck,
I did not know that the KE11-B could be used in the KD11-A!
I never read anything about it, so I do not know ... but the Field Guide
says that the KE11-B is KE11-A compatible. For what that implies ...

According the Fieldguide, the KE11-B can be installed instead of the
KE11-A. That is the EIS board for the 11/35, -40. Note that the 11/35
has several jumpers that need to be set if you install EIS, FIS, or MMU.
Even for the KW11 there is a jumper, IIRC. For the MMU you even must
cut a wire on the backplane!
But this is all clearly describes in the 11/40 CPU manual.
Does the KE11-B fit into the processor slot used by the KE11-A? My
PDP-11/40 has some indication that it had an EAE (sticker above the
backplane has EAE in faded ink), but it has an EIS board.
Are there any spare FIS options floating around?
