Another Qbus hard disk controller -- very similar to MFM controller from DEC Pro; in fact, it is based on a clone of it, and has very similar API (CSR at 174000, vector 300, device name DW). HLE for now, if (when) its full dump surfaces, I may attempt to plug into 8x300 cpu core and mfmhd.cpp.

Second screenshot is of swiss-army knife tool, DESS.SAV (hex editor/assembler/disassembler -- edits memory, files and devices too).
