ShopTalk - Blinkenlights on the PDP: How do they work? What do they do? Find out!
Dave’s Garage: Shop TalkShow Notes
00:00 - Intro 00:20 - Do those lights scrolling across the front, actually signify anything or are they just for looks? 03:27 - Please explain what is the purpose of all the flashing/scrolling lights below the 2 floppy disk drives of your PDP-11? 04:03 - All those LED’s in the front… aren’t they and their PCB blocking the airflow into the chassis? 06:09 - At some point does Kelly LeBrock magically appear in your shower? 06:31 - Sheer poetry! Now, what about implementing DECNet? 07:12 - Did you have to wrestle with DecNet vs 802.3? 07:31 - Can we telnet to it? 08:00 - Are we going to be allowed to telnet and play zork? 08:22 - So uh… Are you hosting a public website on it yet? 08:50 - What can it do online though? 09:47 - Can you send email using the old bang path addresses? 11:06 - Why not whatever the real network would have been back then? 11:57 - Since you got the code working stable, now you should go back and make the code fancier? 13:47 - How long did the ping take to return? 14:08 - A round trip time of exactly 50.001 ms appeared no less than 4 times in the ping testing… what’s with that? 14:36 - What was the communication with the internet? An icmp ping? 15:52- When are you going to get a tape drive for that system? 17:20 - Where did this little magic card come from? 17:59 - How many Unibones has the Unibone manufacturing company sold? 18:44 - Would love to see how you send code to the Unibone. 20:24 - What is the small computer on the Unibone? Is it a rasberry pi or similar? 20:49 - I have a fully working ELF II from Netronics Research… will a Beagle Bone will interface to this? 21:38 - How much more powerful is the Unibone than the PDP? 22:38 - Dave, Do you know how to calibrate the heads on a disk drive with a torque wrench and an analog meter? 24:29 - The WPS-8 operating system has no way to recognize any date or time past 23:59. Dave? Do you know how to fix it? 26:58 - What do you think I should focus on next in my hobbyist OS, a better RNG, a scheduler, an API, or SMP? 28:14 - Is there any way to make the network graphs in Task Manager NOT autoscale? 29:01 - Have you considered experimenting with the Unix V4 image recovered recently? 29:59 - I’ve locked myself out of my WIFI! Do you think, there’s any chance, that I can recover this password anywhere on my computer? 31:15 - Are the reported security issues surrounding windows 11 and Microsoft accounts real? 33:16 - Did you use ai to write that script? 35:19 - Where’s the Dave in the thumbnail? 36:44 - I see lots of car tags with 116. Was 116 your EMP_NO at Microsoft? 39:36 - The Friendly Coder..

What would 1996 Dave think of rebuilding Task Manager with AI? Dave and Glen celebrate 100 episodes of Shop Talk with Windows stories, retro computing, fresh viewer questions, and a look at the community behind the show.Across the first 99 episodes, our comment archive contains more than 23,000 comments. We recognize some familiar contributors, revisit the rebuilt Task Manager episode’s response, and share the most-liked comment in the archive.Then it’s back to your questions: how overlays helped programs fit into limited memory, porting Colossal Cave to a PDP-11, getting started with AI, checking AI-generated code, and using AI for business strategy.Plus: a difficult day at Microsoft, whether Spy++ deserves a modern makeover, TMOG follow-ups, missing hard-drive activity lights, and Deluxe Asteroids.Thank you to everyone who has watched, commented, and kept the conversation going.
Windows war stories meet AI-assisted retro computing in this week’s Shop Talk. Dave and Glen explore AI development on the PDP-11, how they prompt and review generated code, and what older computers can still teach us.Dave discusses improving top for BSD, compiler changes for ksh, and getting Samba running on a 16-bit machine. Viewer questions cover detailed specifications, native apps versus Electron, ownership of AI-generated code, and improving PDP Gary.We also revisit Microsoft Bob’s connection to the Windows XP disc, instant shutdown shortcuts, and a CHKDSK job that could run for days. Plus: TMOG memory usage and temperature graphs, lessons from the TRS-80, Windows 3.1 on modern hardware, and Tempest with a joystick.
PDP Gary has a personality—but how did Dave define it? This week on Shop Talk, Dave and Glen start with Gary, then explore Dave’s recent work using AI on BSD, the PDP kernel, and its peripherals.
What happens when AI stops being a useful tool and starts becoming a crutch?
Can autonomous AI agents cause serious harm without being conscious, sentient or malicious?
