System Clone design files....

[Prime]

Hi all since I have been asked about these :

Here's the Eagle design files for the following :

6502 clone board,
Video board combination of the 40 and 80 column boards, switchable between the two.
Backplane board.
Floppy / Econet board, 8271 based, Econet is implemented by a Master / Arch Econet module.
Gotek clone.
6809 clone board.

These should be able to be opened in any version of Eagle after 6, you should also be able to produce gerbers from them even using the free version, however you will need either the hobby or professional versions to modify them.

I'll update this post later with the design files for the CPLDs on the boards, and the AVR code for the Keyboard interface on the CPU board.

Right here's the Webpack projects for the 6502 & 6809 CPUs, the Video and Floppy boards. You'll need Xilinx webpack (14.7, which is the latest version) to compile these, sorry Webpack is a big download

And here's the AVR source for the PS/2 -> System keyboard interface, which is on the CPU boards.

If you have any questions about any of the above feel free to ask.....

Hi Phil,

What do you use to program your CPLDs?

Hi Phil,

*COUGH* Phill *COUGH*

What do you use to program your CPLDs?

Xilinx webpack and one of the clone Xilinx usb programmers like the one shown on hoglet's wiki page here : https://github.com/hoglet67/AtomBusMon/ ... requisites

Cheers.

Sorry Phill (I'm not very observant most of the time).

...and thanks for the link - I'll check it out.

and again - many thanks for all your hard work

Hi Phill,

What toolchain do you use to compile the Keyboard (AVR) files ?
Atmel Studio ? Or "native" AVRgcc ?

Kind regards, Bram

Beautiful work as always, Phill!

Hi Phill,

What toolchain do you use to compile the Keyboard (AVR) files ?
Atmel Studio ? Or "native" AVRgcc ?

Usually the AVRgcc toolchain, I'm on windows so I (historically) installed WinAVR, and then updated it with the more recent Atmel command line package.

Cheers.

Phill.
