PDP11/20 demo RK05J, PC05 and TU56

[Roland Huisman]

Okay, don't take this one too serious please I've put my PDP11/20 on YouTube for a demo. One can show programmers stuff, I thought I do something different. I hope you like it. And don't mention the way I close the lower RK05 at the end This is not like DEC explains it in the manual...

I did a topic about restoring the RK05 drives

https://forum.vcfed.org/index.php?threads/rk05-disk-drive-versions.78961/

And A story about the PDP11/20

https://forum.vcfed.org/index.php?threads/pdp11-20-restoring.80723/

I didn't do a story on the TC11 and TU56H unfortunately. But it came don to a few broken TTL chips, two burned motor driver boards, bad capacitors in the H720 power, and the two motor capacitors were bad as well...

I still have to fix my 4KW core memory module, but at least it is complete.

Regards, Roland

Good to see how "serious" translates into Dutch! Thanks for the show.

Hi Jack,

Must have been good in the IT business back in the days
Too bad I wasn't around back then...

Regards, Roland

Yes - in the early 1970's, I spent a lot of time playing Space War on the vector display (GT-44) of our PDP-11/45. Couldn't really call it "IT business" though - I was doing "research". :>)

Great production values ... and content. Thanks for creating and sharing this (and the referenced) videos.

Are the paper tape files online somewhere? And, of course, the game executables?
