Show Us Your Curve Tracer

Both the 4145A and B can be fitted with a Gotek or HXC floppy emulator. That would reduce the boot disk problem to making sure you keep an usb stick or sd card around with the right file. Here are some links. Apparently the main challenge is getting the cable pinout right, but 4145A and B are quite similar in that regard.

I'd think you could also get it to work with a Gotek drive and the open source FlashFloppy firmware (cheaper), but I only found a brief mention of that.

Not mine, it's from the 'xofunkox-scientific experiments':

It's not that I don't want to share my PCB's but they're in one file married to the schematics and I'm not willing to put that online, copyright reasons, you know?

Maybe I can unmarry the layout and the schematics... I'll see what I can do.

I'm curious about the overall costs of your version of the ELV KS 7000. Paul's DIY has an updated version of it, but the build cost for his is just under 1,000.00 USD. I posted a reply to the forum post located here: https://www.eevblog.com/forum/projects/1986-transistor-curve-tracer-worth-while-building/

I converted the Gratis documents from ELV to English (although I need someone who speaks/reads German/English to help verify it).

Your take on this is very interesting. What are the copyright issues on yours? Since ELV is giving this information away for free now, it must be for some other reason, correct?

Thanks!

Here is my Doc Brown (Back to the Future) version of the Thaikit. Curve Tracer, octopus for zeners and TCRL tester on one unit.  Makes for easy sorting.
