ACID chip inside
« on: 15:52, 23 October 09 »
Salut à tous....

Well, there are some discussion on many Forums about the ACID chip.

As you know, this is the chip no Amstrad Plus work whithout...
and the most unknown too.

Spanish Amstraders are actually trying to analyse it properly.

French are talking about it, mostly trying to decipher the spanish talks....as we speack spanish like British Cows too. ;)

It would be great to assemble all the stuff from all over the CPC world community, links, etc...on the matter.



Also, It seems there's an Urban Legend about a company with 500 ACID chips to sell.


link to said list :
http://www.n-tronics.com/english/stock/available_stock.php

I sent a mail to them to get more information (price, is it really ACID chip...)

Is it true ? or a CPC mythos ? (seems to be true, lol...merci Fano.)


As you also know, GX/Plus cartridges can be quite expensive on internet !
A  "professionnal" MultiEEprom cartridge production would be great.

But we must check all those information first.

(our pathetic try to understand spanish, lol)



Please, if you have linkto discusssion on the ACID, tell what langage it is too.
I will edit this first post to add them all.then let's Babelfish do the job.

Also, this thread is open to discussion on the ACID interaction with ASIC.


As some crackers say : no protection hasn't been cracked yet...

Well, the ACID is no soft protection (but hardware one...) yet it is still uncracked !

As i replied @cpcrulez , there is a site that pretends to own 500 ACID in stock :http://www.n-tronics.com/english/stock/available_stock.php (stock list 4)
No clues about pricing, i remember TFM/FS posted something about this, maybe he contacted them.

Did the company actually write back anyway? That'd be a great boon...

And if so, a 512Ko Multi E(E)PROM serie would be so fine...

How about buying just a few and testing them in an original cartridge? :)

I'd vote for anything that lets me play Pang on my 6128 Plus.

That's the game that makes the Crummadore kids go very quiet  8)

Hola y Buenos dias,

Today I send a mail to that company (n-tronics) to tell me the price for 25, 50 or 100 pieces of the IL03P1003 Amstard IC.

Depending on the price I will take between 25-100 for FutureSoft projects.

However it shouldn't be a problem to send some of them to interrested people in europe.

Another question is ... is there anybody who can create the boards for the Plus-Cartridges? The 512 KB version in particular.

Au revoir,

Well, now it will be rick dangerous 128+...

any way, this would be so kool if we could produce multi-eeprom cartridges...
As the number of ACID chip seems quite limited...this would be the best method so we could all get one and fuck deeply speculators on Ebay...

Has any one tested to put a 512Ko or 256Ko Rom on a cartridge ?

What kind of software should we put inside this Rom to test it ?
I mean, if we want to test those cartridge, doing measurments is good, this alows to understand...

But a special testing programm would be nice indeed and maybe easier ?

So what kind of software would do it ?

This is what I would like to do, kind of like a ROMbox but as a cartridge (maybe with a switch to select the ROM in use?).

The Pang ROM is 512kb amongst others and people have successfully burnt this to a ROM and used it (here and here).

I would like to make one of these if I could buy a ASIC chip. The PCB is very simple and it would mean not destroying my 6128+ system cartridge.

The Arnold V Diagnostic Cartridge on the WinApe website could be a good place to start to see if the ASIC is working....?

Not really , you can check data redudancy of CPR file  to see it is in fact a 128K ROM.The LK switches seem to be used to invalidate the higher bits in ROM and to roll adressing.
Someone who owns Pang can confirm this fact when looking eprom type used for this game.

Does this mean it would be possible to put in onto a disk?

What is the 'fee cost' and how much is it?
