Hi Chris,

Now I need help, my machine has Pm49FL004 chips as standard, I have some Pm49FL008 too.
I want a 32 M Bit flash chip, if there is such a thing for this type of chip, please let me know the part number. (I would much appreciate the exact detail, as the supplier asks incomprehensible questions)
Sadly the largest I think you can find that will fit your board is 16 Mbit. Look for the part number SST49LF160C-33-4C-NHE.

So am I stuck? They do not make large capacity {SST,Pm}49LF0??) PLCC chips, or is it just an old chip?
I'm afraid SST have the largest PLCC package chips at 16 Mbit. The market demands smaller package chips, so while it's technically trivial none of the flash manufacturers make larger PLCC package chips.
If you have a budget you could buy an Artec dongle (150EUR+VAT) and a PLCC adapter from me (80EUR+VAT) to get 4x32Mbit which is rewritable through a USB port, but it is a bit costly.
You can also stack up to 16 of the 16 Mbit chips on top of each other, switching betwee them with the ID[0..3] lines. Depending on how your mainboard is wired up, you won't even need additional circuitry. And 256 Mbit should be enough for you.
