'83 s130 Digital Dash woes

[Z32LAG]

I have the chronic blinking digital dash on my '83 280ZX GL N/A. This question is way too common, I know, but any "how to remedy" advise or links would be appreciated. Parts are harder and harder to find for this old beauty. 260K original miles on the car and I am convinced when the car finally crumbles the engine will still run strong and true. The s130 is my daily driver. My Z32 is reserved for weekends.

the L6 is a long life workhourse, 3-400k is not uncommon, and even then the cam journals seem to be the most common point of failure

as for the blinking digital dash, most problem with the digital dash go back to the power supply module
