QSIC update - v6 Unix boots and runs

I did implement that too.? Unix doesn't need it but I had to fill the block with something and it wasn't that hard to zero out the value.? I figured something would come along that required it.? There is still a whole lot of the RK11 functionality I need to implement, much having to do with handling and properly reporting error conditions.? It's still pretty cool to boot up Unix and type commands at it.? Doubly cool to watch the indicator panel blink away while I run programs. By the way, that indicator panel has been ridiculously valuable for debugging this thing.? I did it initially just because I thought it would be fun and I needed to take a break from some frustrating bug but it's turned out to be far easier to use than the logic analyzer (which I've never hooked up).? I just generate a custom FPGA load that displays some register I think will tell me what's going on or even sometimes create additional counters with specific triggers that can monitor the internals of my implementation.
