Ok, I stand corrected.

Hm, the above's written on the white label covering the chip... where's the
pocket-knife?... so, no label anymore:

		AM29F040B
		 -120JC V
		9942AVA L
		c1993 AMD

So this is "AMD 4 Megabit (524,288 x 8-Bit) CMOS 5.0 Volt-only, Sector
Erase Flash Memory"

For completeness:

The other 4 RAM chips are "Micron Technology MT4LC1M16E5 16MEG, 1MX16,
3.3V, EDO, 1K REF" (I misread i for 1)
