pdp8/e Problems: KE8-E EAE debugging

I added support to SPCWR3.PA for the VC8/I. http://www.chd.dyndns.org/pdp8/VC8/SPCWR3_vc8i.PA This requires an EAE and now I find out that my untested EAE does not work. The first sign of problems was that the processor paused while running and the only way to stop it was to turn off power. The HALT switch did nothing. I got a copy of MAINDEC-8E-D0LB-D which is EAE test 1 and it locked up pretty much the same way. I removed the EAE and the diagnostic halted at a reasonable place insteading of locking up. The EAE stops the main processor sequencer and then does it's thing and when it is finished, restarts the processor sequencer. I seems to me that this handoff is not occuring properly. The front panel shows that the processor is stuck in Execute (E) State with a 7 in the IR and the PC within one of an EAE instruction. This not gonna be easy to fix. The over-the-top connectors prevent the use of an extender card, so I can't probe anything easily. Since the MAINDEC tests won't run, I will try to figure out which if any of the EAE instructions function and which to not. Since, so far, everything seems to hang, it might be something fundamental, and that might be easier to find. Suggestions, comments please. -chuck
