Thanks for your reply.  I searched the forum and found this which discusses the crystal you suggest.  any other links you know about are appreciated. 
I'm definitely jumping into the deep end of the electronics pool with this, but how better to learn.
thanks again, Ric
2  Using Arduino / Microcontrollers / Powering an AtTiny85 running SoftwareSerial with a battery on: February 10, 2013, 12:02:21 am
Has anyone accomplished powering an attiny85 using softwareSerial with a battery?
I don't get output when i use a battery. Yet, serial output works fine when powered from an arduino connected to USB (500mA).
The Circuit: 9volt battery regulated by a 7805 to 5v, attiny85 decoupled with a .1uF ceramic.
I thought maybe the battery didn't supply enough amps so i tried dropping a 9volt power supply (650mA) in its place, but no luck there either.
I realize this is not an arduino problem so much as a power supply problem, but thought maybe someone out there must have something like this working.  I'm a total beginner when it comes to electronics.. thanks for any help.  Ric
