:-) I actually did a trivial Qbus inside the FPGA so that it became possible to reference devices. Should be possible to adapt the external interface as well, but I won't spend time on that in the near future :-)On Jul 6, 2021, at 3:21 PM, Dave McGuire <mcguire%neurotica.com@localhost> wrote: I am having serious thoughts about doing a system-level design around this. Probably not Qbus but some sort of useful VAX.Sort of half-joking here, but a reasonable first pass might be, ahem, ISA. The interface is trivial, and cards for it are quite easy to build if you can't fine one that does the job off-the-shelf.
