Default speedometer quits

I have a 1993 Corvette c4, , the speedometer reads zero, the security light blinks 3x's every 15 seconds, SYS flashes next to the MPH, and the car wont go over 3000 rpm......HELP.......

I saw this in a post . The same symptoms as I have. The fix was to replace the ECM. I don't think these are available any more. What is the best course of action? Will one off of a camero or transam work? What is your advice?
Here's the post
