------ Sorry if this has been covered many times before, but I don't get a chance to read this group often. Anyway - sometimes when I power on my A2000, the caps lock LED flashes at about a 1 or 2 Hz rate. The keyboard is then useless and nothing typed gets recognized. It seems to have started when I installed the new Kickstart 1.3 ROM, and only happens once in awhile. Usually powering down for a few seconds eliminates the problem, but sometimes I have to wait tens of minutes before I can turn on the power again. I tried Commodore customer support, but they were less than useful. What is the flashing LED trying to tell me? Thanks, Gary Jenkins

I just unplug the keyboard and plug it back in to get it back. Jim

It seems to have started Look on page 3 of Appendix H to the Hardware Reference manual. Briefly, though, it says: One blink Keyboard ROM test failed Two blinks Keyboard RAM test failed Three blinks Watchdog timer test failed Four blinks A short exists between two row lines or one of the seven special control keys. It also says that you probably would not have been able to type anything before this sequence would be completed, but if so, the key codes would be sent to the computer and then a "terminate key stream" code would be sent. There is more information in that appendix. Betty ~ R > >Thanks, >Gary Jenkins Just hope it helps.
