So your code development cycle will be:

1. At home, you write some code, and get it to build.

2. Next day, you take it in to work and hope that you get some time on the PROM programmer to burn it into a chip.

3. Once it's blown, you take it home again and plug it into your board.


So you'll have roughly a 24-hour (at least) turnaround time between making any change in your code, and being able to try it in your board...
