- Sounds good to me. Does anyone know the specifications of the 2000's
- power supply? I recently added a RAM card to mine and it's showing
- signs that the supply is getting marginal. Like sometimes it has
- trouble booting. I'm considering moving the hard drive to an external
- case to take that load off the supply, but if a PC supply has more
- capacity it would be better to replace the Amiga supply with one.

- I can get a 230 watt PC supply for about $30 at the weekend shows.
