Up to this point I had not messed with using the optional EIS card, M7238, KE11-E in my 11/40 system testing. UNIX 6 requires this card, so I am going to test the card. Not sure if it works.
Here is the basic info for the controller:
KE11-E M7238 Extended Instruction Set EK-KE11E-OP-001
KE11-E/F USER MANUAL
The manual says to cut the W1 jumper on the M7233 Decode card, which I did, as part of installation, plus attach the three ribbon cables between the M7238 and M7232.
When I run the system with the EIS card installed and the related jumpers, the system goes DC LO AC LO and I cannot do anything.
I may not be able to boot into XXDP+ to diagnose the problem. But I can try again.
I could not find any XXDP tests, so I put out a request on CCTECH and I was tipped to this page by Chuck Dickman:
KE11-E (EIS) Option Tests
PDP-11/40 Basic CP Test ASH CKBI
PDP-11/40 Basic CP Test ASHC CKBJ
PDP-11/40 Basic CP Test MUL CKBK
PDP-11/40 Basic CP Test DIV CKBL
MUL-DIV Random Exerciser CQKA
NEXT: Put the card on a riser and test the components electrically (caps, etc).
