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.

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

(the 81 had 32K). Nice by the way, and good to see you managed to get a Z80 clocked at 20 MHz.

aeTIos gave me this z80 a while ago.

Ah that's cool of him ^.^

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.

Cool to see that you can finally get that thing to do something ^.^ It's a bunch more useful for you than for me in any case

u/Dream of Omnimaga February 28, 2015, 07:50:42 PM

OMG where did you get those?

u/aetios February 28, 2015, 08:30:28 PM

u/Yuki March 01, 2015, 02:12:06 AM

Free samples? I should get this breadboard to use one of those times.

u/Dream of Omnimaga March 01, 2015, 05:58:10 AM
