Is the 304-00 a 386 or a 486 processor. Can you still get replacement hard/flash drive for them?
If they don't have them here at UsedPhones, Try Novus LLC.
Target Distributing used to sell the replacement flash drive ones but I haven't had to get one in a long time.
Sotel (800-992-9915) replaced our hard drive a year ago with a flash drive and new programming.
I dealt with:
