FPGA replacment for the ZX8301 ULA and more

[lliont]

Hi

Yes there are totally useless pins and one nc pin I think, so if one wishes he could use them, also the wires are not needed for issue 6 and 7 boards.
I like it protruding but maybe a bit less, I make pcb's fast because as you have noticed I change the specs and features constantly ( I hope for the best)

But this I think it is the final version maybe with only minor changes.

As Peter and one's complement suggested an expansion card board is ready and it solves many problems.
It also needs two wires and a small board over zx8301 socket but it is so much easier to install and no need for 3d printed plate for the ports.
I also changed fpga to the newer cyclone 10 LP that I finally found in stock.

Ilint, Brilliant!!

Now that the installation is simpler, will there be (at some point) a public batch available for enthusiasts?

Not bad! Almost Gold Card speed which has Q-Top Index 5.127.

Yes and this with an 8-bit bus vs 16 bit of Gold card but speed is not everything.

I'll try to make a batch after more testing to every QL I can find.

Brilliant work

Yes, the specialty is that you are doing it with a 68008, which gives it a nice retro flavour.

Oh I hadn't noticed the 68HC001FN16, so in the 8 bit data bus mode it provides the all important A0 for the QL (IIRC Gold card ingot has to deal with that).
