Hey everyone, some more questions on my 11/73 project.
A person commented on one of my videos and told me to make sure I had bus termination...
"Make sure the backplane Q termination resistors are installed (XZ1, XZ2, XZ3, and XZ3 side 1 next to slot 8)."
My history working with Unibus machines always said TERMINATE ZE BUS, but I have slightly less experience with QBus. This machine did NOT come with any terminators (well, slight update, it came with an M9302 unibus termination card, but obviously not socketed into the machine). I don't have anything in the backplane other than functional cards that looks anything like a terminator. Perhaps the BA23 is terminated already?
What I'm finding looking up the BDV11 card is it looks like it has a boot rom and diagnostics. I have a working boot rom and diagnostics. Is it just that the KDJ11B has all this already built in? Do I need to hunt down a terminator?
