Also, I've run VE on the TRS-80 for the first time! It doesn't work well though. Screen is mostly blank all the time. I removed instructions from the recipe which became obsolete when Collapse OS became 100% bootstrapped. Also, I've updated instructions to change the NL override which is necessary for blkup to work.
