Anyone know about the 4181R0-009A super dmac chip ?
I thought that the latest was 390537-04 for a4000/3000
What is the abowe chip?

390537-04 is the last ever SDMAC.

I can find no reference to any chip made by MOS/Commodore Semiconductor Group with the numbering 4181R0-009A

Have you read this number off a real chip? Are you sure you wrote it down correctly? Can you post a picture?

Looks like a unique find. Zero worth though.

Perhaps some early development chip ?

It says that in his auctions that they are all pre-release numbering. Not necessarily prototypes.

He's selling several other Amiga chips with similar pre-release numbering.

4171R1-1 Super Buster
4141R0-008A Fat Gary

Like I said, a curiosity, practically zero worth.
