I have serveral MPU modules that have a RAM error that won't clear. WHen doing a complete RAM clear with a 97 chip the lights on the MPU go off as normal.When the clear is complete the top two lights should come on. However, only the top light comes on and I eventually get back to the ram error that will not clear. Does anyone know what RAMS get cleared during this process. I have changed the ram memory chips to no avail. Any help or info would be appeciated. Thanks
