The 6520 replacement is a WDC W65C21N6TPG-14, still being made and sold by most any electronics part sellers.
Thanks for fixing my board! Can't wait to have it back in my hands.
Crazy that those chips are still being made great to see another PET restored back to working order!
Excellent video and work! Always enjoy and learn something new. Thanks for sharing
Love these Chuck. You’re getting better at it all the time!

Thanks. This one was very little effort. Made the video mostly for @ChrisKewl's benefit, unprepared and off the cuff. My biggest problem is audio levels, especially with this one.
Nice video. Get those WDC parts before they are gone!

They still make 'em, although yeah, if they bring them in from China that could be a problem very soon.
Great video! Where can I find the plans for your 4040-esque PETSD case? It's adorable!

I got it from here. AFAIK, they haven't released the STL files. facebook.com/astralabs3dprinting
Good to see another PET back up and running. Here is the link to the Tynemouth PET ROM/RAM for anyone that is interested - www.thefuturewas8bit.com/shop/tynemouth-products/petromram.html

That site looked familiar and then it hit me. It was mentioned on 8-Bit Guy for the Mini PET!
