The ROM expansion board using an EPROM or EEPROM chip for program/data storage. It divides the storage space into two 16K blocks/banks, providing you a stable and fast way to accessing your program/data.
The ROM expansion kit can ship with an OPTIONAL pre-programmed 32K E/EPROM chip, the PAL-1 ROM, for your turnkey experience. The PAL-1 ROM programmed by Jim McClanahan (W4JBM), including Microsoft BASIC, FORTH, VTL-02, and the most in-demand Apple 1 Integer BASIC which we think it has never appeared on KIM-1 clone. PAL-1 ROM also includes eWoz monitor and PBUG(PAL-1 Debugger) monitor. Finally, for convenience, you will get a memory test program in ROM.
In the PAL-1 ROM, Jim shows us two approaches in ROM development. ROM Loader way and directly run way. You can find more details on Jim's github @ https://github.com/w4jbm.
