Arh.. nostalgia. I learnt to programme in PDP-11 assembly on ДВК-1 and БК-0010 somewhere in 89-90. That was my second assembly though. The first one was MOS 650

Arh.. nostalgia. I learnt to programme in PDP-11 assembly on ДВК-1 and БК-0010 somewhere in 89-90. That was my second assembly though. The first one was MOS 6502 on Atari 800s, they were quite popular in USSR in late 80th.Funny thing is that you still can purchase КМ1801ВМ3 chips in Russia for less than a $1 in bulk. I once considered building a ДВК clone to play with and to teach my kids some proper assembly, but then found this DVK-FPGA project on Github: https://github.com/forth32/dvk-fpga https://github.com/forth32/dvk-fpga
- jhallenworld 3y agoYou should resell them on eBay. IM6100s (PDP-8 CPU on a chip) are going for $50 / each.

- kragen 3y agoalso pdp-11 and pdp-8 aren't compatible
- orbital-decay 3y ago> 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.
