Great video! Would love to see more CP/M video programming examples (C, Assembly, Fortran ...). Was the pi approximation taken/inspired from a programming book ? I like to read old programming books, especially ones that use numerical examples.

Great video, really good demo of transferring files from/to the device. Personally I've played with Z80-MBC2.

Great video. I've bought som SLG46826G PLDs. They can be programmed with an Arduino over I2C, and the software is available for both Windows, macOS and Linux. And they are operate between 1.8V and 5V, with 2 different voltages. I'm looking forward to try them out.

amazing, that the software doesn't seem to have a Y2000 problem - or is the clock set to 1924?

Any interest in making one or a few videos about business applications, especially DBASE II (or other database), Visicalc (or other spreadsheet) and Wordstar (or other word processor)? Thanks again for your excellent videos

I love your CP/M videos! PLEASE keep them coming, they are very useful and a great reference

I was a fan of UCSD Pascal and later Borland Pascal. Later I used Borland C for writing embedded code.

I spent countless happy hours programming in Turbo Pascal and Turbo C, then C++. There was Turbo Assembler, Turbo Debugger (which let you use a separate debugging monitor!) They even had Turbo Pascal for the Mac and they developed a really good set of object-oriented GUI tools for DOS, along with the Object Windows Library ... I stayed with them for years as they evolved with the rapid expansion of computing power. But, Borland compilers used to be affordable for hobbyists: now that they've turned into Embracado (or whatever they're called) they seem to want an arm and a leg for the licences and so I use open source compilers when I need to write code, which isn't very often these days. But, fond memories of Borland. Thanks for taking me back in time.

I memeber. As someone who learned how to program on punched cards and typically a several hour wait between submitting a job and discovering you had a syntax error, the introduction of Turbo Pascal was truly amazing.

Completely irrelevant (and enjoyable). When life was simpler. Well presented.

Awesome! Thanks for the video and great work :-)

Maybe I'm just an idiot, but what's the point of this little computer? As far as I can see the only I/O is that USB serial connection. Why wouldn't I just emulate a CP/M machine?

Thanks, this is what I need.

Would it be possible to make a modification and add an interior lithium battery to make it portable? Thank you.

So this means Bus transceiver is protective element for circuit, does't it ? How often can it be happened to have undefined condition in data transmission paths ?

I got one of these too. It had most of the mechanical issues yours had and suffered from counterfeit op-amps. I was eventually able to resolve all the issues. They can be made to meet specifications. Here are two videos where I go through the steps. 1) ruclips.net/video/sttpgZkDx48/видео.html 2) ruclips.net/video/XWJOChu1ZMc/видео.html

👍

Where to buy? Didn't see them at Mouser?

Thanks for the video. Yes, additional options are always a good thing.

V good

I appreciate what you are trying to offer to the community. But, if I might offer a couple bits of feedback. The images of the charts (as well as the overly long pc breadboard wiring) are almost unreadable. I'm using an Android phone and the charts and images are blurry. I imagine on a monitor, they must be unreadable, as well. Compare them with fellow educators EEV, Mr Carlson's Lab, or Great Scott, as examples. It's best just to show a few wires being inserted into the breadboard, while most of the remainder of the board is pre-wired before the video. I'm going to subscribe to your channel as I like your idea of explaining individual ICs.

Thanks for this useful video. I have few questions: 1) What is the maximum current it can provide? 2) Does it come with a power adapter? If no, which one to use? 3) Can I run it from my computer too? I mean is it possible to interface it with a free software and operate it accordingly? 4) Can we generate frequency in decimals too, like 114.223Hz?

Great 👍

I can't hear it ??😢

It is inexpensive but wow, way off on max freq spec. What does the filter actually do, clean up the waveforms at all?
