83Plus:BCALLs:807B

Synopsis

Unofficial Name: GetByteOrBoot

BCALL Address: 807B

This BCALL receives a byte from the link assist. If it is unsuccessful, it displays an error message, waits for a keypress, and boots the calculator (clearing all RAM or waiting for a valid OS).

Inputs

None

Outputs

• C: byte received

Destroys

• All

Comments

If a validated OS is not detected, this routine will wait to receive one instead of resetting RAM.

This routine uses only the link assist, so do not use it on an original 83+.
