; DESCRIPTION: This module contains a little function to that gives a variable ; delay with the same resolution as the SYSCLK period (on a ; single-clocker, that is). It's called with the number of ; periods to delay in R7. To be precise, isn't R7 the number of NOP periods to delay in addition to the fixed overhead of calling the function & setting up the jump...?

| What about a Delay like this. | 01/01/70 00:00 | |
| No, it won't. | 01/01/70 00:00 | |
