Hi all, i have the GQ4X (4x4) and i'm wondering if its possible to read and write the Mach series of chips?

They are not in the device list but wondered if they would be known as anything else and if so what adapter would i need?

the chips are PLCC 44 chips.

If its not possible with the gq4x does anyone know of a cheap programmer that could read/write them?

Basically i have a device known as a FastATA for the Amiga computer and its not working, i have borrowed a friends and swapped the chips out for mine and verified mine works and even identified which ic the issue. If i can read his and write myself a new one i could repair my device as the original manufacturer doesn't offer replacement parts.

Thanks

Would you have a part number and datasheet?

That datasheet is quite vague on the programming procedure.

This one is no longer an issue, after contacting the manufacturer and after a lengthy chat where they initially refused they backed down and sold me a replacement Mach chip. Thanks for looking though :)

Seldom will manufacturers provide such chips! Did they charge you much?

Not so bad for an OEM part.
