Flebay has some used ones around $1.5k. I wonder how much this model MSRP brand new? Either way, $300 is a steal!

The TDS500, 600 and 700 series can expand memory by removing zero ohm resistors.

Give it a month and the acquisition ASICs will blow up and the caps will eat through the board traces. Can’t stand these scopes.

Love this. I knew nothing about oscilloscopes until just a few months ago, when reasearched and bought one from a science lab. It wasfor a personal side project. I gutted it out and installed a mini PC inside, and now i run AI models into it. It's like my personal AI assistance. Hooked up to OpenAI realtime voice, grok bot, claude code, etc so I can command it to do stuff even when my main computer is off.

I just mainly love the retro-moder look of it. Here's a link to how it looks, for those curious:

I had now idea there was such a huge second-hand market for those. It was such a great opportunity to learn about this tech.
