Note: My CHIP-8 version still has the interpreter at M(0000), but the operating System starts at M(7000). Display page is at M(6F00).
In order to use the New ELF II hex keypad, I changed one byte in the CHIP-8 keyboard scan routine. I disregard the scan byte in RF.0.
I replaced the 8F instruction with 6C before exiting routine.

Things you may want to change with this program:
1. Change byte at M(0001) from 88 to 01 to go directly to Super Basic.
2. After pressing 'C' there's a delay starting at M(314D) . Change byte at M(314D) from F8 to D5 to return from routine.
3. Change byte at M(1829) from 79 to F9 to move the stack pointer higher up thus increasing the amount of memory for BASIC programs and data.
Do a MEM command before and after to see the increase.
