Z820 - Z80 computer
« on: February 27, 2015, 08:02:09 pm »
Original post: http://8times8.eeems.me:81/blog/index-beta.php?thread=16

This afternoon I started building this z80 computer. It will run at 20MHz, have 128K of ram and 8K of rom. The operating system will be stored on an external medium such as floppy disks.


If you like my work, why not give me an internet?

It's more of a project name. The computer will get a proper name once I come up with a catchy one.

Lol it has less ROM than the TI-81 :P (the 81 had 32K). Nice by the way, and good to see you managed to get a Z80 clocked at 20 MHz. :)

Just bought a bunch of parts. I got a 20MHz crystal, a bunch of capacitors and a connector for the floppy drive. I don't know which floppy drive controller I will use yet.
