I tested and verified the operation of the 64K (Not 128K) RAM card I have installed.

I tested four M7762 RL/02 controllers. One is outright bad, the other three all seem to have no issue initiating the boot (the READY light blips out for a milisecond whe DL0 is run) but they all bomb after writing the 000 000 page data to initiate the disk read.

The current configuration has only the main CPU backplane and a 1/2 backplane. There is not enough room for the M930 bus terminator, I have to remove it in order to give up a slot for the M7762 drive controller.

Let's try putting the M930 back into the last slot. I will also remove the M9312 and G7273 and replace with the RL02 controller. I will toggle-in the bootstrap manually and attempt to boot.
