So one of the things that I want to do is create my own computer from scratch.
There are several SBC (single board computer) designs on the internet and the unofficial Z80 webpage is a great place to start if you want to create your own. Another awesome place is hackaday.io .
I seen a lot of examples and I’m going to try and mod\marry a lot of them together to get what I want. I’ll use KiCad to create designs. There is other FOSS (Free and Open Source Software) like Fritzing ; however, I found it very buggy and crashed…a lot..
Here is my current parts list:
|Zilog Z80||Z80 CPU||Main CPU|
|Atmel AT28C256||256K (32K x 8)Paged Parallel EEPROM||BIOS\ROM|
|Hitachi HM6116LP-4||2048-word X 8bit High Speed CMOS Static RAM||Main RAM|
|Motorola MC6850CP||Asynchronous communications interface adapter||Serial I\O|
More parts will be needed (i.e. memory bank separator and other accessories that I’ll want to add) and I’ll try to update this list as needed.
