Well...
Looks like an EPROM. I imagine there was a glass window on top of the
chip...More or less the equivalent of floppy disk on a chip. Copied with
an EPROM programmer. Good luck in finding someone that can copy an
identical one for you...

Hi,
As my transputer collection increases, I just received a broken BBK-S4
(Sparc-based SBUS transputer link adapter). As far as I can tell, the
only broken piece is the firmware IC. The IC actually was broken in
half exposing the actual IC. I think someone was trying to extract it
incorrectly and it opened up. The delicate wires are snapped as
well. I hope that the firmware is downloaded to the chip each time it
is fired up, but I am not sure. The chip is labelled as:
TOSHIBA
TC57H256D-70
JAPAN 8906YAA
VPP 12.5V
Does anyone know what type of IC this is and where I can obtain one?
I would love to install this on my IPX and connect my T805-30MHz
Xplorer to it. Thanks
