Randy, I need a controller for a Hamilton Auto-Cashier Model# ACW-5-CRC The Controller Model# ACW v4.20C . I read in former threads where a spare might be available. Hamilton has it new for $1600 (too high for the present budget). Damage to the original board probably deem it non repairable. I've followed the forum for years and just, recently joined the posts. Thanks, Bill Bramlett
