Installing New Screen RAM Sockets Into The 2nd Commodore PET 2001 1978 Board 2114 - Episode 1476
11This the board that I had working and then went back during the burn-in session...and the collective wisdom told me to check the 2114 screen ram chips...and now it is time to install the new sockets in this board so it can be tested and hopefully that is the end of this journey...on this machine...but we shall see...these machines are a delicate balance...so, sockets in, solder them and be ready for a great success...or not!
From previous videos that are part of this project...
It is time to test the 2114 RAM chips...the pins are always a bit harder to work with on recently pulled chips...as there will be remnants of solder and some of the pins might need a bit of tweaking...but in they must go...so I have 4 chips from the two machines and my guess is that 3 are good and 1 is bad...but I could be wrong...I am mighty sure that 2 are good...and we shall soon see what is what...and then I will see where this journey takes me...if 3 of them are ok, I have to find another to get both machines working...but I would like to think I have enough spares around that I can muster up 1 or perhaps 2 working chips...we shall soon see what is what...
This is a long video...it is my first go at replacing sockets in a computer in a long time...and there are of course issues...but as always, take to slow, be patient...and do not touch the hot part of the soldering iron...and if you think you messed up, take your time and make sure that all is well and good...
I can not get stalled on this project...I can not...so, I have to get out today and get the things that I need to get on this and get this resolved...and can I find my soldering iron...no, of course not...anyway, I need to get sockets, solder them into two PET boards, and then try the 2114 RAM chips...I would suspect there is one bad one...perhaps two...but we shall see...so I need 18 pin sockets, a soldering iron, and there are other sockets I am looking for that I would suspect they do not have...but I will look, I will ask...more and more this store seems to have less and less that I need...so I guess I will go to the online world and get things shipped...perhaps Rudy knows of a good place to source vintage parts...maybe...anyway, off I go to the store...there are a couple of surprises in this one...and indeed, I am missing my remote lav microphone...I will check the mail soon...things should arrive...I hope...also, I think my one phone has some serious issues with the internal microphone...and that does not help matters at all...this too shall pass...if you know of a good place to order things from, let me know!
