One of the nerdiest video I've seen in a while. 😅

Thank you Thank you

October 2024! 😅 👍🏾👍🏾👍🏾

Geez it looks as slow, noisy and "reliable" as a regular cassette deck. At the time, I would die for one of those drives but not having ever seen it up close, and now watching this video, I am truly happy because I didn't own one... 😂

Thanks Man, your course is an incredible input to knowledge. I am very surprised that 6 years later only 33 persons liked this when they rushed on AI courses. But as it is said when back to fondamentals, only genius undersatand and appreciate

Que toston de video, le tuve que subir la velocidad

Programming Z80 is a sheer joy after suffering 6502 😊

the link is not good.

I so wanted one of these back in 85 when I was 14. Never managed to get one. I wonder what 14 year old me would have thought of NVME gen 5 storage.

What a crazy processor!

Is it possible to find the code of this game anywhere? I've just copies Serger's Minimax8085 and it is interesting to start this game! Thank you!

hi. what was the typical use for this chip?

Hello, where i can find this demo program?

I didn't know they made a version of the Klein Computer like this.

3:50 :)

Why whisper? Afraid someone will hear? This thing looks very nifty.

Could you speak properly? I cannot understand you. Unbelievable!

nice video, but actually i still have a doubt about this emulator, im trying to make a sum program on it but i didn't understand the instructions set, so im quite lost on how to make it perhaps you could help me with it

Hi. Thank you for your video. That helped me so much for interfacing a z80 pio to my z80 microprofessor. I have the one build by wichit sirichote. Can you tel me where i can find the hex code you wrote for testing the z80 pio please?

My mom had one of these, I have either her old one or one just like it - she had hers in the 1950's or early 60's.

Why are you whispering.

Воу, спосибо большое за ваш труд! Всё очень понятно )

so there's a fast way for multiplying and deviding by 10 in assembly. this is very useful even for programming in higher level languages. now I 'm understandying why multiplying a float number by 10 in C++ I obtain e precise result. thank you!

Embora ja tenha passado muito tempo, tenho aprendido muito com seus videos. Gosto muito dos Microprocessadores z80. por isso estou aprendendo a programa-los... Muito obrigado...

Mas estudo tambem os codigos para o 8080 e 8085 pois a forma como voce ensina acrescenta conhecimento.

Estou estudando todos os seus videos. E tenho aprendido muito. Ate comprei uma licenca do Z80 Simulator IDE.. estou estudando com seus videos. Estou no Brasil. Muito obrigado...

I wanted to write down a comment but it has been already done: your job here is very appreciated BUT it's absurd keeping people to spend twice the time for listening to the explanation of a processor they won't use. I think it won't be hard to split these videos and maybe dubbing them

Hello, Thank you very much for this series of three videos which is a mine of information on this legendary processor, the INTEL 4004. Your way of explaining is very clear and very pleasant 👍

Thanks for this. Apart from a ZX81 and ZX Spectrum (Z80 machines), I also have a Soviet Mikrolab KR580IK80 which has a KR580VM80A processor which as I understand it is a clone of the Intel 8080A. The latter can only be programmed in machine code, so it's how I got into this area

I just bough one and refurbished it on my channel :D

What a fun trip down memory lane, thank you! Have you considered dumping the ROM and disassembling it? I'm so curious what kind of A.I. they came up with in 1980 with so little code.

Thank you for your clear and slow paced tutorial. I'm still pretty new to the world of CPUs, but am fascinated by its inner workings, and the 4004 is a great place to start. I managed to find the 4004 Assembly source code of the Busicom 145 PF calculator, and am particularly interested in how on Earth they programmed their device to compute square roots with 10 digits. Have you had a look at the code? It's very short!

This is a randy radio shack.

I never owned one of those. Thank you for the upload.

Thank you for this video. Very much appreciated.

My introduction course to microprocessors was a course run by Siemens South Africa on an 8080 trainer. At the end of the week course we programmed a clock. That was in 1980.

Got a link to this simulator? What platforms?

What a satisfying sound that thing makes.

I aspire to use my PC E220 in such creative ways... :)

That is the perfect lullaby.

Hi thanks for an excellent video on the Zilog PIO. I have used the Zilog PIO chip to print to a dot matrix printer in one of my Z80 computers. But I did not have to utilize the handshaking/interrupt capability of the PIO. Now I am trying to connect two Z80 computers via the PIO chip as in the example on page 377 of the textbook "The Z80 Microprocessor" by Ramesh Gaonkar. His example utilizes handshaking and the Z80 interrupt mode 2 and the bidirectional data transfer mode 2 of the PIO. Unfortunately, the interrupt pin on the PIO is always low, so that the Z80 processor is interrupted when it should not be interrupted. Do you know what I am doing wrong? Should not the PIO interrupt pin be high (not active) until the strobe signal is sent? If so, what makes that interrupt pin low, at the start of the code?

En el minuto 12 se come al rey....

Ty, underrated channel!

Ty for the 4004 series... :)

I like that you talk slowly, cause I'm not english native. You explain very well and clearly, I Like :)

Thanks for that overview of this wunderfull device!!!

Thanks. Just ordered PIO from Jameco for my uProfessor that I bought on eBay. Had one originally in 1981 but lent it out and never got it back. Fun playing with it again.

I'm the 1000 view!

Great video demo. I've got the version with a grey LCD display instead of red LEDs. But this computer lacks one very important thing: it doesn't show when you're in check. Thanks for sharing.
