I've been in touch with Kyle, and can't find my boards. I have 2 sets that
should be here by Friday and will check the revs as soon as they get here.
I will try to look for prints and fiche by tomorrow night. I plan on
sending a package to Kyle by Friday, express mail. Do either of you have
access to a fiche reader?
If there is anything else I can do let me know.

Hi Folks,
We're trying to get an EAE (extended arithmetic element) board set working
in a PDP-8/e. It turns out that DEC made changes which render M8340 rev.D
incompatible with M8341 rev.D. (Both of the boards we have are rev.D,
sigh.) M8340 rev.D requires at least an M8341 rev.E.
We would like to modify the boards to be compatible but the only schematic
of M8340 that we've been able to find is rev.F. So it's difficult to figure
out what changes are needed.
If anyone has an M8340 schematic earlier than rev.F or an M8341 rev.D sch,
that would be a huge help.
The goal is to get Spacewar! working on the PDP-8/e for the upcoming VCFSE
show. This version of Spacewar! requires the EAE. We GOTTA get Spacewar!
working for the PDP-8's 50th! :) Please help.
Thanks,
Steve
PS: The revision letter can be found in the lower right-hand corner of the
DEC schematics that I have.
