That card looks good to me
You need to find one of 3 flash chips supported by the firmware, these are the AM29LV040, PM39LV040, MX29LV040. And either flash it externally or stick it on the card blank and flash the card with the DOS flashing program, just be aware it is a PLCC32 chip which can be a bit tricky to solder. The only problem is none of these chips are easy to find in the UK, so you need to order them from china or the US (I do have a tube of the AM29LV040's though, so i could send you one)
Have a read of this thread, it details everything you need to know to flash the cards
Hey Max, thanks for the link to the thread - there's a wealth of information there and it makes a lot more sense to me. I'm not too familiar with how to flash a card externally, but perhaps getting the chip onto the card and then plugging it into my PC and flashing the appropriate firmware that way is an option I can consider.
I'm naturally very interested in one of your AM29LV040 chips. Should we keep it in the back of our minds for one of the inevitable purchases I make off you?
If it turns out I haven't found anything else to pick up, perhaps in a few weeks, we can come back to the subject of the chip? Thanks once again for all your assistance.
