Thanks Todd for all your support!
Please update the link for the 8080A board to https://koyado.com/heathkit/New-H8-Website/h8-8080a-eeprom-ram-uart-ha8-8.html
As it is pointing right now to the H8 8080A memory board and not the CPU board.
I received the Z180 and the 8080A CPU’s board this weekend and they look great. After testing the CR2032 coin battery to backup the memory RAM on both boards, I observed that it will drained the coin battery faster and for the Z180 even worse due to the 1MB RAM capacity. I added a connector to provide power externally from the +5V-STB PC power supply or from a 5V wall transformer. Also, on the Z180 CPU you can drive the bus (/02)with the 2MHz clock, CPU output clock or CPU input clock. Also, there are more improvements to each board based on my testing with the proto boards.
Thanks,
Norberto

Thanks go to you Norberto and Glenn and everyone else who is spending so much time and money to design, organize and bring in new people.
Oops, thanks for the correction Norberto. Should be fixed now.
Thanks,
Todd

That is correct! That is my target date to complete such board into production. Why? Because it is my birthday. 😊
