Synopsis

Hypothesized Official Name: appData

Memory Address: 8000

Length: 256 bytes

This appears to be the same as the old appData. It can generally be used for scrap RAM.

Comments

This looks like a great place to put an interrupt vector table. But beware that any BCALL that copies code to RAM for execution---including all flash BCALLs---will overwrite the last byte of the IVT, which would reside at 8100. Such routines also always disable interrupts temporarily and set IM 1.
