You don't need to open the 850. Use an Atari program to read the ROM, and report back in the thread: 2 Quote Link to comment Share on other sites More sharing options...
+Nezgar Posted April 28, 2021 Share Posted April 28, 2021 Yup best to use the dump program, removes all risk of damage. You cant directly read a 2332 mask rom in a TL866. Next easiest way I've found is by swapping the chip into an atari cart and saving memory to disk from dos. Quote Link to comment Share on other sites More sharing options...
moonlight_mile Posted April 28, 2021 Share Posted April 28, 2021 Thanks all. I was able to read the rom. I had to save it to a real floppy. I didn’t have any virtual d1: set up. I will upload it in a little while to see if it is new or just a copy of these roms floating around. Quote Link to comment Share on other sites More sharing options...

+x=usr(1536) Posted April 29, 2021 Share Posted April 29, 2021 Has anyone rounded up the CRCs for the various ROM revisions in one place? Quote Link to comment Share on other sites More sharing options...
+MrFish Posted April 29, 2021 Share Posted April 29, 2021 (edited) I have two ROM's with the following CRC's: 2CF990B9 9201359A I believe these are the two being tossed around in this thread, and maybe the only two (?). [Edit] I meant to say in this thread (didn't realize there were two threads being posted in ATM -- although there's apparently some cross-posting of files too): Bare 850 Printed Circuit Board Edited April 29, 2021 by MrFish 1 Quote Link to comment Share on other sites More sharing options...
_The Doctor__ Posted July 12, 2021 Share Posted July 12, 2021 (edited) What's the list up to? I can't rightly recall exactly but there should be at least 4... @MrFish, did you post your 9201359A rom up for comparison Edited July 12, 2021 by _The Doctor__ Quote Link to comment Share on other sites More sharing options...
