Proto-board Z80 computer

diy_zilog

We’ve seen  Z80 processor based computers before but they usually use a printed circuit board to easily and reliably connect all the components. [Marton] sent us his Z80 based computer from a while back that is built entirely on prototyping board. He made his own video board that utilizes a TV as the monitor and his own mainboard incorporating a keyboard controller. The system runs at 4 MHz, has 32k of ram, and runs [Marton's] own system software which he has posted. Its quite impressive and we love the protoboard porn with thousands of grey wires running everywhere.

[Marton] used the resources on [Hans Summers'] site for his project. Make sure to check it out if you’re interested in a broader background concerning DIY Zilog Z80 computers.

    Needs to be wired with enamelled wire rather than plastic coated greyness for it to be proto board porn!

  3. OrderZero says:

    I love how much detail he put into this and how all he did was reuse old parts ^^

  4. yellowduck says:

    I agree with James. As a young engineer I built many proto boards with Vero wire. Shame I didn’t keep any photos!

    Wow.

    Incredible labor of love.

    A friend of mine built one of these a while ago, though he used a modified BBC Basic setup for the OS rather than a completely custom one. http://benryves.com/projects/z80computer

  7. Huh says:

    How does he reprogram the arduino?

  8. devin says:

    haha an arduino joke, you’re funny as hell. no really, stop shitting up the comments you cunt.

  9. Jonimus says:

    seriously they finally post something worth while and you make an arduino joke. Plus the z80 is way better than the arduino anyway. :P

    Hurrah for the Z80! :-D

  11. nave.notnilc says:

    Can it run CP/M?

  12. Huh says:

    @devin Reminded of the special olympics much? Your still a retard!

  13. Richard says:

    @ nave.notnilc
    It probably could run CP/M with a little bit of tweakery, although it could really do with 64k to do it comfortably – especially if it’s going to be networked.
    I still miss my old TRS80/II that ran something very similar to CP/M on a z80 with 64k…

    Z80 Rulez. +1 for the post and protoz80 owner gets +10

  15. eye says:

    I like the image you have posted here.

    Ahh, the memories… Did this with a Z80A when I was 13 years old on a blue 22/44 protoboard using bits of 25-pair telco wire, so mine was much more colorful… :)

    I’ve soldered my ZX-81 kit in those days. You wrestled a different kind of monster, so I call you Sir.

  18. jan says:

    is it possible to connect it to an arduino?

  19. jadon says:

    i have an old ti-81 graphing calculator with a z-80 any hacks for it any one know
