I was able to use my microscope to roughly see the scrubbed off part numbers of the chips used and I was able to locate a data sheet with the partial part number. Knowing this I used a raspberry pi pico since it has a pair of i2c buses to probe the i2c lines of the two chips. I was able to get the whole display to light up! But dang it it has a huge load of segments:

The digits of the clock are made up of squares of 8 of these little triangles plus the center delineator and the bottom is a 12 digit 15 segment alpha numeric line with a : and a . Plus the other various icons. So I will work on this later too when I get the chance.

Here is an update on my repair of a Northstar CT-1000 Digital Flight Bag C (ca. 1999) computer.

It has hung at the bios screen because the original IBM 2GB travelstar drive it had was on the way out and I wanted to try and preserve the irreplaceable driver files on it. I changed it to a larger spinning rust drive but I think the BIOS does not deal with the larger file size very well or that it has the wrong format type. I am going to mess around with it later and if need be move it to an internal CF card.

Since it has a two card PCMCIA slot I think it will make an awesome tablet using the PicoPCMCIA project.

I will update my progress as soon as I get a caddy and some Disk Mode flash drives for it.

Please take care of each other.
