Greetings All!
i finally got some time to assemble and test my 512K SRAM Expansion Board and everything seems to work as expected! Schematic, design files, and gerbers area available on the project page at https://hackaday.io/project/171128-ibm-pcjr-512k-memory-expansion-board. The design is open source (non-commercial). if anyone is interested in purchasing one, let me know!
