Hi Guys
i'm looking for a cgs65CE02 to my Apple //e, it is a Commodore version of 65c02, if anyone has one and wants to sell it, leave a message

That chip was only ever used in the Commodore serial expander for the Amiga 2000. It will be exceedingly hard to find. Especially because it is a 16-bit chip with a full 16-bit stack mode, not just a clone of the 65c02. Therefore, collectors pretty much have bought all of these.

honestly with the chances of finding someone who has one of those and is also willing to sell it (likely for a very very high price due to the rarity), it would probably be a lot cheaper and faster to learn hardware design and code up your own 65CE02 softcore for an FPGA.

... and then see if you can sell them on eBay

You want to put a 'CE02 in an Apple IIe? Isn't that rather a bold experiment? I'm not criticizing the idea, but it certainly provokes my curiosity!

According to Wikipedia, the orininal IIe comes with a plain, ol' 6502, while the Enhanced and Extended IIe's use a 65C02. The 'CE02 is (mostly?*) pin compatible, but the cycle counts for many of the instructions are different (ie, faster), which may present a problem for any code that's timing sensitive. Moreover, according to a link in this post by BigEd, the 'CE02 "has a bug in decimal mode: SBC doesn't quite work."

I might be able to help in your search . But maybe you could share your plans with us, please.

*- the 'CE02 datasheet mentions DMA capability, which to me suggests the chip has a BE input. However, the pinout shown is identical to that for a 6502 -- ie, no BE pin.

In 1988 my 65C02 got six new registers and 44 new full-speed instructions!

Welcome, Vinci! I hope you have success in your experiments. (As Jeff notes, what you propose is not totally straightforward.)

(Thanks, Jeff, for the link back to that earlier post: I've now repaired the links there.)
