New yerar, new CPC board

[skywalky]

Also will be available the board only soon?

Adding 128K RAM for loosing one MX4 slot (X-MEM) is not really a good deal.
But, nice about the PSU input and the MiniDIN RGB.

since I'll be adding either a mother 4x or symbiface anyway so the 128k and one less slot does not bother me, actually I'd rather have the 128k and only 2 slots.

In both cases, the 128K are useless because replaced by the connected expansion.

and I will still be using without any expansion as well. This will become my main CPC basic coding rig. Leaving the pluses to play games and make cart images for c4cpc.

Good to hear from you @Piotr

Version 4.0 is even more interesting

I allways thought on 128k's as main expansion as you know  . Even with x-mem or symbiface, if you want to remove the boards you still have 128k's and be totally cpc classic compatible.

I'm anxious too for the boards

nice board Piotr !!!

OK...

[Piotr]

Is two slots only becouse i do also expansion board for Just CPC 128 k. So one slot for card, second for something like motherX but internial. Floppy drive interface is on board, so you can connect floppy, gotek, hxc ?

[TotO]

OK. I though that orriginal goal was to be able to have all features on the main board.
(not to need to extend again with an extra-board)

[Piotr]

Ok, so i add one slot. In next month you do a next 2 cards and... again my board don't have enough slots.....

[TotO]

I have not understood your answer.

[Piotr]

Are you doing still new cards, so it still will not be enough slots on my board. Maybe the opposite? Make one integrated card 

[TotO]

I don't know if I will relase more boards, but other peoples do.

Originaly, your board design was populated with 4 slots, then 3, now 2...
I can suppose the final version will only have 1 to plug a ribbon cable to the internal "motherX4". 

After, it is your choice and if peoples are happy to get 128K by default, it is perfect.
But... Now you handle the PAL, why not embedding the 512K RAM directly to the main board?

[Joseman]

I think that 1 or 2 slots, then use a motherx4 board is a perfect solution for any case and anybody!

I think that embedding  512k RAM directly is impossible if you use original cpc chips, that (i think) is the goal for this board!.

Just saying...

[Piotr]

Besides, I can always do both versions Boards for issue 3 waiting...

Talking about integration, why do you use 64kx1bit RAM where you could at least use 64kx4bit ? 4 devices instead of 16 !

[CraigsBar]

It still go an expansion port there.

[Piotr]

Gerald, becouse i have 3000 pieces in my drawer.

When I read your wishlist, and everybody have different opinion - this reminds me of forum about new Amiga. I meant too many, too different wish it's not help and result is no new Amiga.

So Piotr don't listen them. And if you need ideas what to do with unnecessary parts look here:

In the German ct computer magazine was an article about replacing RAM chips. So a 6128 became 512 KB RAM - and 256 KB acessible by the CRTC.    You can look that up in .... the CPCWiki!

Without modifying nothing on the motherboard? ? ? only the ram chips? ?

C't 512 KB internal RAM expansion - CPCWiki

It seems that there are compatibility problems and you have to add a daughterboard with more logic... i don't think that it's necessary right now with a lot of ram expansions available for the cpc...

Still, it's a rather neat solution.
