Default Re: I found it! A very sorry looking MK14.

I tried remove each RAM chip one at a time, I only have the standard pair of RAM fitted. Result in both cases was all segments on bright on the rightmost digit and all segments on dim on the second from right. I didn’t want to try leaving it running like that for long enough to take pictures.

When I was first trying to get my MK14 running again, before I replaced the RAM chips, it was still showing four digits and two digits in the correct place but stepping through memory would make it jump to random addresses on the display. I was fairly sure it was a RAM issue, which turned out to be the case, but it was only partially faulty RAM.
