I must admitt that I watch your video from time to time just for plesure of looking at a well crafted piece of hobby retro hardware. Nice, clean wiring, clear component layout, and most of all - the front panel - that acrylic cover is way beyond most simmilar projects I`ve seen. 7-segments look sooo cool underneath them :D. Those keys also fits nicely. I personally think that for a project like this, presentation is a very important factor. Keep up the good work and keep inspiring people !
This looks sweet, so cute and functional (for a Z80 computer, for learning) The wiring is neat, the layout aswell. The acrylic is the nicest touch ive seen sofar. So now I stop with all the compliments and come with a question: Can you keep doing what you do, but please stay enjoying to do so. I love to see more. (More miniture vehicles is fine aswell, awesome.)
Hi Bill, These tact switches are called "KC-901 Series". But I don't know manufacturer. If you want more information,please see below web site. www.jw-shop.com/P-keyboard-mswitch10/page30/detail.htm Thank you.
Very nice work! I assembled a Z80 myself but I have found it hard to use commercial software like the Basic you used in your Project. As commercial software require some standards like specific address for video and ports, in my project I wrote a custom BIOS to deal with SD Card and Video board. Anyways, nice work!
Dear Jon Loruddo, I'm using key encoder IC with dynamic key scanning . The key encorder IC is MM74C923, which is 20 key encorder. If you do not get it, MM74C922 can be substituted. However, since the MM74C922 is a 16-key encoder, its capability needs to be extended. Hmm .... Am I answering your question? Thank you,
Ok, I understand. I don't know maker name,but I know the parts number of these tact switch is 'KC-901TC'. I bought it on below site. www.jw-shop.com/P-keyboard-mswitch10/page30/detail.htm Thank you,
Dear Landon, I obtained the music from free music site,which named "Musmus". On this site said "This music is made for calm game use." URL is below. Musmus: musmus.main.jp/ The 4th Dimantion: musmus.main.jp/music/tw020.mp3 Thanks,
Excellent. I would love to make my own computer, but haven't a clue. Is that hexadecimal coding you're doing on it? Finished product looks awesome. I also watched it again to listen to the funky music.
Dear faultelectronica, Thank you for your comment. When I demonstrated my comuter in this video,I was testing 'address set', 'memory read&write' and 'execute memory clear program on ROM'. Thank you,

Dear Warren, I customaized Tiny BASIC monitor source code, which was downloaded from www.amy.hi-ho.ne.jp/officetetsu/sbc/index.html File name is TBZ80.zip. Thank you,
Thank you for your comments. I will focus on growing my computer than writing a document. I would like to write a document if I can do it. However, I think that it takes more time yet.

Currently I am creating a new video.I do not know if it can meet expectations, but I hope you please look forward to it.
I love everything about this, right down to the point-to-point wiring. Beautiful work!
The transparent front panel is such a brilliant idea, though it almost looks like a modern piece of gear now haha
Superb build!
very rad, elegant design.. and I'm not even from the computer field. luv it!
The good taste shows even in choice of music!

+Nico Vijlbrief (CodeAsm) Thank you very much!
Of course,I'm keep going :-)
Beautiful build!
Thank you.
very nice! very elegant design. :)
+Stephen Scutt Thank you!
every home will have one of these someday!
Thank you.I hope so :-)
Computers are just a fad like television
Great project, better than my Z80 Card.......
Thank you.I also like your Z80 computer.
show!!
congratulations !
+Marcelo Ribeiro Thank you.
Gorgeous build...
One of the niciest Homebrew Z-80 ever built.
Thanks!
Tokugg -
Great project! Whose keys & keycaps did you use - do you have make & model#?
Thank you!

Thank you.
How is properly called the black acrylic thing for the displays?
Thank you for your comments.
This acrylic called ""Gray smoke".
Thanks,
Do you have a schematic ?
What are those flat cable connectors called?
This thing is a beauty btw.
Dear Njubivoje,
The connector name is 'XG4A-4035'.It is made by OMRON.
Thank you,

Thank you very much.
I watched your fantastic Z80 computer video on TH-cam.
I think your computer is my goal.
Thanks,
I should post some vids of mine i made some time. Im even getting a PCB printed. hope it goes well!
Super clean looking! How long did you spend on this project? Also, what's the power consumption? Would it be possible to run on batteries?
hello, i would like to know how you made the keyboard and display interface. I am having difficulties in the design of mine.
Love the computer. Hate the BGM. :-) Are you planning on building more peripherals?
+cb meeks Thank you for your comment.I am planning to implement some parts for running CP/M enviroment.
For example CF or SD card drive, etc...
What did you use for the control pad? How did you make it?
Dear SlykeThePhoxenix,
I'm using key encoder IC with dynamic key scanning .
The key encorder IC is MM74C923, which is 20 key encorder.
Regards,
What type of keys is the keypad made from?

I need to know what that background music is.
Dear Landon,
I obtained the music from free music site,which named "Musmus".
On this site said "This music is made for calm game use."
URL is below.

Nice!
+JG Thanks,bro!
Nice approach to a Z80 system. The control unit is nice. :) Where did you get those keys?
Greetings from the city where your PIO was produced.

Thank you,
Cool!
+Slovenija12345 Thanks. :-)
2x z80 ?
But will it play D00M !!!??!
Technically yes since it’s Turing complete :)
Hello i tried building simply computer on breadboard but not work properly inven on low step clock.
Dear NANO-Serwis,
I don't think so.
I think poor contact or the wiring mistakes.
Good luck!
TK-80を連想させるKeyのカラーリング良いですね、
BASICは東大版の移植かしらね。
ご視聴有難うございます。
よくお分かりで。TK-80を意識しています。本当はEX-80っぽく行きたかったのですが。
BASICはご指摘の通り東大版をちょっといじったものです。
有難うございます。
Did you use a stock basic Z80 rom or did you have to customize it?
Dear Warren,
I customaized Tiny BASIC monitor source code, which was downloaded from www.amy.hi-ho.ne.jp/officetetsu/sbc/index.html
File name is TBZ80.zip.
Thank you,
NIIIIICE!
I'm very much interest is replicating this. Is there any information you could suppley me with?
Thank you for your comments.
I will focus on growing my computer than writing a document.
I would like to write a document if I can do it.
However, I think that it takes more time yet.
凄い
If it were a product I would buy one
:P i need to get one
Ha ha thanks!
what do u mean
dude can I buy one
schematics please!
I'm sorry.I have no schematics for this computer.
thanks anyway
Music drove me mad, thumbs down
Mute button is just as easy as thumbs down.
So cool
