First post, so please excuse me if this is the wrong sub-forum.

I have a PET ROM tester board that has a 901447-18 chip on it and i could only find one single reference for that in all of the Google searchiverse.
Maybe someone here has any knowledge about this?
:?:

The tester board is the same as seen here under "Diagnostic Clip/Inside View", a rather crudely made 320370 Rev A:
http://www.6502.org/users/andre/petindex/diag/index.html

The only search result on google is this:
http://mhv.bplaced.net/cbmroms/cbmroms.php

And i just added it to here:
https://www.c64-wiki.com/wiki/MOS_Technology_Products

Welcome! It would be great if you could find a way - a safe way - to dump this ROM, and share the contents.

Thank you for the welcome.
I hope i can get it out of the socket safely, there is quite a bit of corrosion on the pins on one side.

I have a Retro Chip Tester Pro and it supports the 2316B type ROMs so i should be able to read it out.

You might be able to free up those pins by putting a drop of WD-40 on each one using a cotton swab (aka Q-Tip®) and letting it “soak” for about 20 minutes. WD-40 is non-conductive and safe for this sort of thing.

Didn't have any WD-40 but figured my Deoxit should work similar. Let it soak for an hour and the chip came out smooth as butter.

I ran it through the RCTP several times to make sure i got the same checksum (081c7aad) and then dumped the ROM to SD.

So here it is, i haven't looked at the disassembly yet but i can see some readable text in there so i'm hopeful it worked OK.

Embed the binary file into a ZIP file and you should be okay.

Alright, here's a *.zip with the .bin binaries and the .txt disassembly.
8)

NOTE: I updated the zip file with the new disassembly starting at $9800

Looking through the disassembly, i put it at $9000 as a base but that might not be right.

The last 4 bytes have jump vectors to $9800 and $FFAA. Hopefully that makes sense to somebody out there.
:wink:

Looking at the absolute references in the early part of the code $9800 might bea good candidate for the origin?

I agree, the base address looks to be $9800. I did another disassembly with that, see attached .txt file.
:)

PS: I also updated the .zip file above with the new disassembly
