This test should verify that the CPU performs the correct read's and write's on the external bus. This is important when addressing I/O devices, and this issue is created as a result of this comment: …

If one has a display / monitor that does not support HDMI but only DVI, then the screen stays black when the core is started. Our current "workaround" for this situation is this recipe that users can …

This issue is part of #67 and issue #66.
We (Mirko and I) are thinking about breakpoint and single step support in QNICE and came up with the following idea:
* We will use one of the two spare bit…

Make IO$GETCHAR smarter, so that switching STDIN does not require "one last keypress" on the old STDIN any more before reading from the new STDIN

One of the basic ideas of QNICE-FPGA is, that it is meant to be highly portable. For sure we are not there, yet ;-)
Currently, everything is quite Xilinx specific.

I'm following the "first steps" tutorial and I ran into one very small and easily solvable snag:

As a result of our video conference last Saturday: For solving everything related to future ISA changes in V1.7 and later (project "clean ISA", issues #57 and #55 etc.) and the related potentially lar…

* We need to document these semantics somewhere (possible interrupt device documentation, best practice programming, ...)
* One new best practice is, to set the ISR to the own RTI before disabling an…
