Then we look around the device registers and pick up a few more bits that were unused in the RP11 and we end up with a 28-bit Linear Block Address which works out to a ridiculously huge disk for any PDP-11 ever conceived.? But yeah, we'll document it. There will also be an entirely new programming interface into the QSIC itself, mainly having to do with configuration (like whether or not the RP11 implementation is stock or extended and how portions of the SD cards are mapped to various disk packs mounted on the emulated disk drives).? I intend to write that up too so that people are able to write programs for their favorite OS that drive the device however they wish.? I may joke about pointing people to the source to figure out how it works (it was hard to write, it should be hard to read) but I actually quite like well-done documentation and will endeavor to produce some.
