  CAT          CATalogue - output the contents of current directory
  RM           to Raster Memory - load contents of named file in framebuffer
  MV           Make Virtual - map the file into memory and output the address
  LS           Load System - attempt to reboot using the named file as the kernel
  CD           Create Directory - self-explanatory

So, after typing that in and probably SYSing (C=64 BASIC command for executing machine code from arbitrary memory location) to some address, it did print out a two-digit (eight-bit) hex checksum after every BASIC line I entered on the C=64 and the program listing in the book had the correct checksums for every line, so spotting errors was more or less instantaneous.

This stuff brings memories.

It sure did help later with career in IT to have understood this kind of stuff at age of around ten.

Once I get this done, I get back to the actual project of a 2.11-BSD based handheld computing appliance.

Also there is this thing called "day job".

Anecdote aside, it certainly doesn't hurt to be able to debug things without a debugger if it comes to that.

Most horses that are put down would be perfectly fine for human consumption, but slaughterhouses do not buy them for the aforementioned reason. The primary consumer of horse meat in Finland is the sausage industry, and they buy cheap South American meat by ton.

Volvo had a very strong safety emphasis already in the '50s, introducing many firsts in the automotive safety field. In that decade they introduced shoulder belts as a world first and padded dashboard as an European first (Tucker had this already in '40s but only 51 cars were ever made).

I do not know what's referred to as "original OSes" but many old operating systems had actually pretty decent security architecture. MULTICS and VMS, for example, and many others too.

They have some pretty far-out stuff. Woggle Bug and Waveform City are outstandingly weird in a very creative way.
