Heh 16 meg is pushing it... 
But there was Flash to save the day!
Just imagine if flash memory was never invented. Would make for some interesting USB memory sticks |

Ahh but they made a 32Mbit too (and a 64 but I never have been able to find one)

It's really a 32 MBit EPROM (2M x 16). I found a datasheet of that M27C322:

No Chiefish is correct, it is a 4Mbit EPROM 256kx16

Oh, I mixed it. I thought he ment your M27C322 EPROM 
His one is, of course, a 4 MBit EPROM.

Anyone know any of the part numbers for the 64m eproms, I would mind trying to hunt a couple down.

CPUShack & me would be happy to find some also
The only possible manufacturer was ST Micro.. there part number was M27C642
Here is a marketing picture

Wow look at the size of that window, its like 1/3rd of the length of the eprom. Very cool to see.

As would most EPROM collectors among us I know I'd be happy to find one or more of the largest capacity
