DIY-A586 v1.6 by piotr_go

Is it possible to use both cores at the same time?

Yes, but you have to edit (with some hexedit) the name of the * .A586 ROM if they require other versions.

Wouldn't you make patha to 3.2.1?

I made an a586 -auto and can't enter the menu.
Can it be avoided somehow?

Hold down reset while turning on.

Thanks a lot.


Was it possible to fix something with PFS?
FFS often has validation problems.

It will come down with it yet.

I noticed a bug in your CORE.
Sometimes the FDD doesn't work after the reset (I have gotek from Zaxon).
He does not see it, the reset does not help, you need to reload the cora.

The CIA must be too fast, check this out:
https://github.com/piotr-go/FPGA/blob/master/DIY-A586/cores/amiga/mikan/mikan_v0.1.1.a586

Mikan 0.1.2:
- audio fixes (again )
- Copper fixed
- image crop fixes (PrintScrn)

... and news 2.0:

Not yet well tested.
At the moment I do not plan to share.

Way to go. This 2.0 looks great when it comes to memory.

When it comes to FAST, in 1.6 it would probably be able to increase, the paths are there. CHIP is another matter, the extra DMA logic in Spartan does not fit.
Any ideas on how to use 8MB CHIP?

Can you make a video on YT of the mikan core and of board rev2.0? Regards

What are the improvements of rev2.0?

When I finish the AGA core. It will come down with it yet.
In days I will release version v1.9 (I skipped a few numbers ).

Larger FPGA, 32MB RAM, USB, Audio DAC.
