Hi, I have a '2600 with a faulty RIOT that I want to replace.

 

I found some cheap R6532P's on AliExpress; are they any good to replace the broken R6532-15 RIOT?

 

And what is the difference between a R6532P and a R6532AP?

 

Thanks!

I forget what the difference is but the P will work fine in a 2600

Thanks for the info! I just ordered a R6532P from China for $2 and free shipping.

 

For that kind of money I'm fine taking the risk :-)

 

And I did some investigation on the R6532AP, which seems to be a 2MHz version, while the R6532P is 1MHz.

Yes. The P suffix just indicates a plastic (instead of ceramic) case.  It corresponds to a traditional vintage 6532 from any of the usual manufacturers who had licensed the 65xx chipset from MOS.

That was what I was thinking but didnt want to bother looking it up

 

and yes DrVenkman is correct the P is for plastic shell (vs ceramic) , its the A vs non A that's the important part

Careful ordering those 6532's from China. Some are DOA and most of them are fakes that are out of spec or just don't work at all.

Doesn't the 6532 have a custom ROM part and that is what the -15 represents? Or perhaps that only applies to 6530. I know that in Commodore PET circles, each of these are unique though it has been discussed about replacement solutions with a programmable ROM part so one chip should match them all.

Exactly, I ordered 5 a few years ago for about $8. One didn't work, the other four are fine. Well worth it.

Update: I received the R6532P from AliExpress today and replaced it with the broken RIOT. All works fine and I've got a working 4-switch woody again. Yay!
