Plus Cartridges and custom EPROMs

reflote .

I bought a top 853. I don't have (at the moment) m27c1001. But I remember i conserve and old chip bios from my old pentium 200 mmx.

So I rescue them from a old box and put it in the programmer to test it.

My surprise is the chip is flash 128k x 8, but with a little diferent requeriments in the pin supply.

Is posible this chip can work in the gx4000/plus.?

In the table The chip need high voltage in we (p in m27c1001) in read mode, but the m27c1001 work with the two states.

But in the cartridge(i not sure) pin 31 is connected to vcc permanently?

This chip will work fine in a standard cartridge if the links have been set correctly.

Thank you.

And 29C010?

I ask, becasue i can buy this memory localy. I can buy a m27c1001, but if i buy the m27, i need buy an eeprom eraser to china.

PD the links default is the burning rubber links

I think the 29C010 has the same pinout as the 27C1001 (you'd have to check the datasheet), so it should be fine. Only the 512K Flash/EEPROM has a different pinout to its EPROM equivalent.

Finally i bought 29f010, and it works perfect. The chip from pentium bios also work o.k. Unfortunly, the  original gx4000 power supply broken  and the pentium chip bios die with it wtf.(gx4000 an acid is o.k).

I have extracted the eprom from cartridge withouth hot issues in the acid, i used this:

Works perfect, after finish, acid is cold and i can extract and recicle the eprom.

I found rick dangeorous and beyond of ice palace(cartridge from cpc power)  not work in gx400 and amstrad classics is unusable(no keyboard in gx4000).

Many of these "homebrew" or cartridge "hacks" have not been tested on gx4000 and never modified to work with joystick.

I took a lot of time to make the Stryker cart work on gx4000.

Thats why mark it as gx4000 games in cpcpower has no sense .

great work in stryker cart. The other big game fault in gx4000 is prehistorik 2 maybe with no$scart.
