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
