I love it! Keep your great work up! It is nice to watch. The music is cool, too.

Thank you very much!

can you share the Assembler that you use to compile the code?

[@Z80System]

Hello, Yes, all ASM code are in the dropbox link you can find in each video description.

@@Z80System thankyou, but im talking about the program that you use to convert the assembly code in .hex or .bin file

[@Z80System]

Hello, Ok, sorry, the website is here : www.tni.nl/products/tniasm.html and the link for the program to run under DOS COMMAND : www.tni.nl/products/tniasm045.zip

Hello, I really liked the project and I am reproducing on my protoboard, but I did not find in the "Z80Motherboard.sch" scheme the information: ENABLE, ENABLE_WRITE_DATA, CLOCK_READ_DATA, EN, RW, RS that appear in "LCD128X64.sch" Thank you for your attention ! Thanks

[@Z80System]

Hello, In fact this 6 labels are the same as D0 to D5 from the Data bus. I renamed them on the LCD128x64 schematics for the J_0x01 connector, in order to remember what pin is used for, but It really come from the 8 bit data generated by the program and send to the I/O port n°1. It is set by the lcd_write_instruction(), lcd_write_data(), lcd_read_ctrl() and lcd_read_data() functions. They are ordered like this : ENABLE_WRITE_DATA = bit 5 CLOCK_READ_DATA = bit 4 RST = bit 3 EN = bit 2 RW = bit 1 RS = bit 0 it is use with PORT 1. Im' really happy you try to build the project, thank you ! If you find any optimisation in my ASM code (and I m sure there will be), just let me know. :)

@@Z80System Got it, you can leave my friend, as soon as it's working I'll post a video here and give you the link, thank you very much for your attention

Hello, I loved the videos, could you give me the link to download the electronic schematics? thanks!

[@Z80System]

Hello, thanks for your support. I add the schematics download link in the description.
