Tony Duell says he has a copy of the datasheet.

All of the HHP modules I have use a chip 1LJ4 and if this is the chip that HHP has always used it would be capable of supporting 64K of RAM. Maybe if I play around with the pins that appear to be for configuration and then observe what it reports, I can learn more about it.
