> I once considered building a ДВК clone to play with and to teach my kids some proper assembly I actually built a custom board with a K1801VM1 a while back to teach my son programming basics from the ground up. It's slow as molasses, but great at this purpose. The PDP-11 ISA is simple and comprehensible, as well as the 1801 microarchitecture. Underclocking and a few LEDs in the key points of the board can easily illustrate the entire process; it's very direct and you can almost physically see it "thinking" under the hood. We used that board to drive our Christmas lights and for simple games before moving to something more high-level.
