Hi, I tried to run the diskless controller test on my PDP8/A. It fails before any tests has been executed. I suspect that my RL8A controller is broken. The CPU tests and the memory tests works fine.
The test stopped @ address 5713 (display shows 5714), MD buff = 7402, AC = 0 Does anybody have the source code to this test? Earlier someone got the test instructions photographed from microfishie. The complete story is that the machine worked just fine, booted OS/8. Then I changed the CPU from KK8A -> KK8E. The KK8E had some problems, but works fine now. But now the machine doesn't boot OS/8 with any of the CPU's. The diskless controller test stops at the same location with any CPU. /Anders
