Had a wafer I got on ebay, was marked M4640, and appears to be a Conexant baseband processor with a ARM7TDMI and DSP

Also a ZMD U555 EPROM, cool that it has the crossed swords on the die

these done on my scanner, and not the cleanest, but fun nonetheless

I redid the U555 at higher res and filtered in photoshop, amazing what the old scanner can do
