Busy-wait delay: outer loop of 0A iterations, inner loop of 00 (256 cycles) each. Stashes and restores BC.

| Delay_Short | DA97 | PUSH BC | Stash BC on the stack. | |
| DA98 | LD C,$0A | C=0A (outer loop counter). | ||
| Delay_Short_OuterLoop | DA9A | LD B,$00 | Inner loop: spin B from 00 (256 iterations per pass). | |
