I now have RC-850 Repair PALS available for the Computer Interface Board. Previously unrepairable, the Computer Interface Board can now be repaired keeping RC-850's on the air for years to come.
The PAL is available for $55.00 plus $8.00 shipping in the United States. Send a check or money order for $63.00 US to Paul Kindell 810 W. Pekin Road, Lebanon Ohio, 45036-9785. The PAL will be sent out the next work day after receiving the check.
