Batboard

Just picked up mint full keypad 1 meg Astro Saber VHF for $40. Host, & DSP the newest. The DSP starts with I, while all my others start with N. Years ago I remember reading the difference, but can't find it. FC is 580001-000200-8. What does the I mean? GARY

As I remember from readings over at P25, it had to do with the manufacturer of the flash chips being different.

Thanks.
