NEC V20 CPU: A bit of pep for an XT
- rbanffy 11d agoI knew it was possible to run CP/M programs (and CP/M itself) on my PC with its V20, but I never found out how.
- tom_ 11d agoI just got served a big chunk of JSON, not even pretty-printed, with the text in there... somewhere. Difficulty level: quite high, even in reader mode. (same on macOS+Firefox and iPhone+Safari)
- drcongo 11d agoYou're not alone.
- glimshe 11d agoI thought it was an error message but I can't tell from my phone using Brave.
- vlasky 11d agoI think it's a caching issue. I got it to render properly by adding a cache-busting query string to the URL: https://dfarq.homeip.net/nec-v20-cpu-a-bit-of-pep-for-an-xt/?v=1 https://dfarq.homeip.net/nec-v20-cpu-a-bit-of-pep-for-an-xt/...
- bell-cot 11d agoAppears to be fixed now. (If not - zoom way in, and it's relatively readable.)
- bell-cot 11d agoNot mentioned - the NEC V30 CPU, which was the V20's 8086-replacement near-twin: https://en.wikipedia.org/wiki/NEC_V20#Variants_and_successors https://en.wikipedia.org/wiki/NEC_V20#Variants_and_successor... IIR, the V30 provided a notably better improvement (over the 8086), because the 16-bit memory bus meant it was less often starved for bandwidth.
