Note to Thread:
they would be unlikely to be EEPROMS - those are the Electrically Erasable variety.
EPROMS (the UV jobs) are IIRC cheaper.
aside: I got 3.1 ROMs from Eyetech with OS3.5 - they didnt have windows. I didnt remove the stickers either !!
The Metal shield is to comply with various (FCC and EU to name but two) regulations on EMI compliance - ElectroMagnetic Interference - its to stop all that EM noise leaking out and interfering with other things, and vice versa. shouldnt cause much of a problem without it really.
yes, just lob a sticker over the window bit.
