Concerning "original games productions", of course such re-writable cartridge" bypass every software-commercial concepts.
Of course you'ld have to get the "ACID part" first and once, so the "games part" are less expensives because 1 less component and smaller printed-cards...
We must first see if we can manage this ACID emulation... Hope my brother is as good as I believe...
Your design ideas would be nicely complemented by my earlier proposal of a wirelessly remote-programmable cartridge and a rebirth of Amstrad's demonstrator (multi-cartridge menu):

Yeah but perhaps too costly...as too much expensives components needed...perhaps

We all have a PC...
Just having a simple PLUS cartridge that could be re-filled in Datas by a PC is quite good enough...
the wireless or the Menu aspect is a bit too much acctually (yet would be ideal).


My Brother admited his use of the microcontroller for this may be a "borderline".
But he thinks this can be done by precalculating stuffs...
You know, the codes the ACID give to the ASIC... those can certainly be precalculated...

So we'll see if this works.
He recieved some more components...soon we'll try to achive this.


The only way this can be well done is to permit GX4000 possessors to have new games...
We, the PLUS  computer geeks (no consolefags.. sort of...)... we can still homebrew some sort of more advanced device... After all, on a computer with Extension port, a ROM board is already doing all this...

So just if We can manage to test a working component emulated ASIC...We can then custom this as will...(we can do it also by simply cannibilising cartridges...)

But to be viable the 2 part cartridges should be supplied with a production of good games...certainly the harder part...

2 part cartridges :
1st game cost more (2 parts) but latter games don't have to feature another ACID...so quite costless... (package, casing, ROM, board and connector...).

A simple cartrige able to receive a little SD card to emulate ROM is pretty suffisant.Now you spoke about , i need this  :-*
"NOP" is the perfect program : short , fast and (known) bug free

More this would be usefull not only for pure cartridge game but we could write software to 'mount' cartridges as read-only disc...

QuoteTimings   Although the functionatlity of the ACID chip is known. The timings of   the signals coming from the computer is still unknown   (reverse-engineering was done on a ACID chip, without owning a   CPC+/GX4000). 

       
  • CLK is known to be 4MHz, and SIN is known to be updated on   falling edge of CLK, as seen on this picture
  • Judging from the ACID chip, /CCLR is checked on falling edge   of CLK. However, juding from this picture, /CCLR is changing on   falling edge of CLK. If this is true (the picture resolution isn't   perfect), then it's unclear how the ACID can interprete /CCLR in a   stable way while it's changing. Possibly, it can't do that at all (ie.   it might act unstable, and the CPC+ might need to retry sending /CCLR   several times). 

            
    • A picture showing CLK and /CCLR without ACID connected (at   better resolution) would help! 
    • A picture showing CLK and /CCLR with ACID connected would be   nice, too (trigerred on the LAST /CCLR coming from the CPC). 
  • The /CE timing is still unknown, too. The ACID might check   A0-A7 on raising or falling edge of /CE. Or, on raising or falling edge   of CLK while /CE being LOW. Or at whatever other time. 

            
    • A picture showing CLK and /CE would help! 
    • Best also showing one or more of the A0-A7 signals. 
OK, got a call from my brother.
He recieved the component (Microcntroller, Flash memories...)

But he had some questions concerning the Clk signal.

Is it the same as for the CPU from the Amstrad ?

His aim would be to synchronise the new emulated ACID with the cPU, and using some additionnal chip, overclock the 4MHz signal to 16MHz...
Then he thinks if this can be done, the rest is mostly software/programm optimisation.

As this sufggests, most of the timing part on real hardware is still not well documented...


If the spanish who did some measure can supply stuff, this may well help, folks.

Did somebody try to buy ACID chips? Did you get them?

Who wants to buy them? I would like to get them, but n-tronics didn't answer my email.

Any ideas?

mmm,You can try register there:

or ask there
http://www.powercomponents.nl/webshop/index.aspx?a=3&artcode=IL03P1003

I think n-tronics not respond because many people ask for the acid, but nobody buy

them.must think they are kidding.

Or register here:http://www.brokerforum.com/electronic-components-search-en.jsa?originalFullPartNumber=il03p1003&x=49&y=16&hasNoSearchCriteria=false&searchPartNoLabelValue=Search+Part+Number

try register to contact directly with provider without intermidiary such as n tronic.

TFM/FS you are german right?.n- tronics is in germany,telephone  they directly.They speak german.

I can think of nothing else.

Well, universe is funny every now and in :o  Today I got finally a mail from them!

But... in the post before they wanted 4 Euros - now they want 7,86 Euros!!! I wrote them back that this is more than expected, that it makes no sense to buy it for that prices (final price of hardware) and if they can make me a better offer.
Thay wanted 4 Euros before, I don't pay more now. If they want that much, they can sit on them as long as they want. But for less than 4 Euros I would get a 100 of them an make the cardridges. - Which also means if somebody wants one or two of them, you would get it. However 7,86 is way to much. For 6,66 Euro I can already add a 256 KB ROM box to the CPC (but about this we talk another day).

Look... that's what they wrote...:

That is the law of murphy.

Maybe that price is with shipping?

Yes, Murphy law, and not the fist time positive :-)) I got a better price for 100 pieces, it's still 6,85 Euros - a pain in the ass. However nobody will ever produce an ACID for a cheaper price ;-) So I ordered them.

:_) I'm a bit confused, they still produce it? or they sold all item 'till the stock is out?


steve

It is no longer being made, but one company seems to have a small quantity of old stock, when this stock is gone, we will have to clone the chip which may cost more than the price asked for this old stock.

jbaudrand

:) thanks for explain it. hop you do amazing game with it!

I'll use them all for cartridges with FutureOS on it :-)

You have to take pictures of the package when arrive.For posterity.

They have already updated the database only 400 available.

It's actually amazing they didn't write that stock off ten or fifteen years ago. Can you imagine thise box sitting in a corner for all these years, properly stocked and maintained in their database? :D

Judging by their website, they seem to specialise in stocking and supplying out of manufacture parts. So, a box full of ACID chips is probably not the most bizarre thing they have.  :)

Gryzor

You're probably right about that. I'd like to take a tour of their warehouse!

Octoate

I think last but not least we got it...

Hi Octoate, can you provide some more details? (Whenever you're back from the meeting and have got some rest ;)

It's very interesting, and the cartridge of the photo is interesting too.

Tell us more, please.

spybro

looking forward to that
please provide some more info
GREAT WORK!
