For anyone that needs the BIOS of the FMA3300A, I got you. Bare in mind that this is designated for the 3300A, and I'm not sure if it would work in a standard 3300, since I don't have one to test (although if anyone here is wanting to get rid of one, hit me up, only prerequisite is that you're in Europe). The only difference seems to be that the A has 2 serial ports, where the 3300 has only 1 so it might work.
The EPROM (yes, "UV erasable") is a Fairchild Semiconductor 27C010 - only problem is it doesn't have a window for you to erase it! Instead, it has a plastic knockout of where it was supposed to be. I haven't bothered to look into alternatives, but I'm sure they're plentiful. Besides, this chip is discontinued, so tough luck getting it anywhere for a decent price.
Also, using the XGecu software I had to disable the "Check ID" option for it to read properly, despite the fact that it is available in the chip menu.
