Sharp MZ-80K core by Gehstock

Postby DrOG » Wed Feb 14, 2018 6:38 am

In his GitHub repository:

https://github.com/Gehstock/Mist_FPGA/t ... Z-80K_MiST

.rbf in the 'snapshot' folder.

As I see still a beta, but seems to be less buggy that the previous one. No garbage on screen, but VGA out is low compatibility despite the standard resolution & refresh rate (640x480@60Hz)

Hi!

Tested briefly the core, video output seems to be VGA compatible (1024x768@60Hz), but keyboard does not work, and no option for loading files. See attachment (sorry for the ugly screenshot).

Thanks for your work! :cheers:

Best reards: Gábor

A quick VGA-only test:

Sharp MZ-80A and MZ-80K: Screen looks good. The keyboard reacts to a few keys, but not as it should (it results in different characters on the screen than those you pressed).

Robotron KC 87 (Z 9001): interestingly, on my old CRT screen there is some graphic problem on the top that Gábor's screen does not show.
After resetting, the screen correctly scrolls upwards into position, just like on the real machine.

@Gehstock: sorry that I completely missed the last PM you sent me (I was busy with other stuff), but fortunately other members were able to fill in.
