There are only four significant chips. a) the upper right is the right package style and about the right pin count to be the PTSC chip The PSC-1000 is in a 100 pin square package, 25 pins on a side, not rectangular like this part. The logo on the part is for Rochester Electronics, which bills itself as a source for discontinued electronics. This chip could be an ethernet controller, since it's next to the Valor coupling transformer, or Rochester might be acting as a fab for a custom Lantornics chip. d) the 32 pin socketed part seems to be a programmable device (I'm guessing programmable because it's socketed), I would guess this to be flash memory. The 32 pin PLCC package is common for flash. c) the smaller chip by the connector appears to be flash memory. If d) is flash then c) is likely DRAM.
