The question is, how do I mount my RL02 pack with the software I saved?

(That's a 14" removable platter drive that stored 5 million bytes! Amazing. A couple decades and the media is essentially unreadable. I suppose someone with a STM could work it out.)

I'm sure you can find someone online with a working RL02 who'd be happy to create an image of your disk for you.

# pwd /usr/ken # vi vi: not found Wow, it's like I was traveling in a time machine back to 70's and saw Ken Thompson hacking. One thing that has always taken for granted is that vi is the ubiquitous editor in Unix world, it's NOT true, :)

I think this is when you learn that ed is truly the ubiquitous editor. None of these fancy visual editors like vi, also if the date is to be believed, this predates vi by a year (1976 is when Joy created it if I remember right).

Also, I just realized its been a long time since I had to use ed, but this is fun. Its like a more civilized age of unix, ls -l doesn't print groups. So much fun to be had here.

I tried vi and edit commands and they didn't work. Thanks for this hint about ed. Works in the this pdp emulator.

Out of curiosity I also tried ed on my Ubuntu and it works here too. Shouldn't obsolete tools like these be removed from the newer linux kernels? Or is there a significant population that still uses it directly or indirectly (using some tools that use ed)?
