Thanks.  I had a brief look around the 36-bit systems last night.  

One of my tests for a Pi 3 B was to build and run the SIMH HP3000 on it.  Being able to do that means having git to get the SIMH source, gcc and gmake to build, (curl|wget) to get the MPE V/R bits, unzip to extract.  The prerequisites were what I wanted for other Pi stuff and this was a good workflow to find out what was missing from the Jessie Lite image (yes it was that long ago, in Stretch and Buster I think I have found all those packages are already present).

One of the things I have found with the Pi is, the low end micro SD cards (P*tr**t and K*ngst*n would match the ones that did this) are lossy storage.  It’s not that they wear out, it’s that they lose bits.  Switching power supply to one sufficient for the Pi did not solve this problem, they continued to lose bits.
