Strike 2 on 2nd TI-99/4A hardware help!

Quote:Great!
I don't think a lot of people can appreciate when you take something that for most part was a door stop and bring it back to life.
You could build yourself a diagnostic cart..wouldn't have helped you with this though. There is also a diagnostic version that will load into a supercart you could build also.

Since you changed all the ram at once i guess you don't know how many failed.

Hi,

Yes, I tend to make these repairs a sort of mission because when I finally get it working there's a real feeling of accomplishment there..

Also, I did find out which RAM was bad - it was the 3rd one in from the outside edge of the mobo - I always test them one by one after removal so I can keep up my stock of IC's!

I'd love to try out a diag cart, but what I've found so far is usually too expensive!
