DavidMil Posted January 16, 2018 Share Posted January 16, 2018 I found three interesting EPROM chips today. One says: 1200XL SW16 U12 V1.0 LOW And the two really interesting ones say: EPYX P/N 614R-A 1983 EPYX P/N 614R-B 1983 All three are 2764 chips. The edges are frayed and slightly lifted, but the windows are still totally covered. I can't wait to put them in my Pro Burner and see if there is anything on them! Anyone have any clues?

Rybags Posted January 16, 2018 Share Posted January 16, 2018 (edited) 1200XL has 2 OS sockets 8K each which should explain the first - the OS sockets are labelled U12 and U13 on the board. Epyx ones, probably a game. If you dump them can you do individual per chip. It should be easy enough to ID what they are. If you append the pairs together you should be able to use as cart and OS images in emulators. Edited January 16, 2018 by Rybags Quote Link to comment Share on other sites More sharing options...
+kheller2 Posted January 16, 2018 Share Posted January 16, 2018 It’s interesting the 1200xl says sw16 on it. It is probably the normal rev 10 but a dump would be nice and a picture of the sticker. 5 Quote Link to comment Share on other sites More sharing options...

DavidMil Posted January 17, 2018 Author Share Posted January 17, 2018 Epyx game : Is it Gateway to Apshai? 614R seems to reference that. I sure hope it does. That was one of my favorite games. But can you explain how does 614R reference that? Thanks, David Quote Link to comment Share on other sites More sharing options...

David Potentially refers to “Sweet 16”, the project code name for what became the 1200XL. Quote Link to comment Share on other sites More sharing options...

DavidMil Posted January 17, 2018 Author Share Posted January 17, 2018 Here is a picture of the three EPROM's. Do you have any idea of how many pictures I had to take without a flash to get this picture? A lot! DavidMil Quote Link to comment Share on other sites More sharing options...
_The Doctor__ Posted January 17, 2018 Share Posted January 17, 2018 (edited) well the fact it's labeled lo usually implies there should also be a HI, as that's the norm unless someone labeled lo out of habbit, in any event a dump of the roms and a look at what in em will shed light on a number of things...

Kyle22 Posted January 18, 2018 Share Posted January 18, 2018 Please guys, remember that a camera flash won't hurt a COVERED EPROM. Even an uncovered one would suffer very minimal (if any) damage. That video of a camera flash (if it is to be believed) only caused transient glitches. It did not destroy data. the ST came right back every time. Laws of Physics here! Don't be paranoid.

DavidMil Posted January 18, 2018 Author Share Posted January 18, 2018 Do you have those sitting on a wool or cotton blanket? Is that a good idea? Normally I'd laugh at anyone suggesting that there is any static build up in Houston because of our normal 80% or so humidity. But because the temp has been below freezing for several days, your right. I took special caution with those chips. Also I had some fun with the dog (accidently). I walked across the carpet and went to pet her and ended up zapping her on the nose! She let out a yelp, ran to my wife, and hasn't so much as looked at me the rest of the day today.

DavidMil Posted January 18, 2018 Author Share Posted January 18, 2018 I see you have a ProBurner too! Yup. A bright orange, 2 pound, left hand slot only, Thompson Pro Burner. DavidMil Quote Link to comment Share on other sites More sharing options...
SoundGammon Posted January 18, 2018 Share Posted January 18, 2018 Is it the newer one with XL-XE on it? Quote Link to comment Share on other sites More sharing options...
DavidMil Posted January 18, 2018 Author Share Posted January 18, 2018 I'm guessing it is the newer one because the label says for Atari 400, 800, XL, and XE computers. I can't find a copyright date or a publication date on the burner or the docs. The labels on the burner are also orange. I can post a picture if you'd like. DavidMil PS. I'm going to put the 1200XL Eprom on the burner this evening, and see what comes up. DM Quote Link to comment Share on other sites More sharing options...

I can easily compare it to the known LO ROMs out there for the 1200XL. Quote Link to comment Share on other sites More sharing options...
+CharlieChaplin Posted January 18, 2018 Share Posted January 18, 2018 (edited) Look here at the model #: https://atariage.com/software_page.php?SoftwareID=3872 The cartridge shell of this Epyx cart. is often (always?) used for Eproms. They often (always?) used a slightly different cart. shell for ROMs, e.g. this one: https://atariage.com/software_page.php?SoftwareLabelID=2525 So I would say Epyx "Gateway to Apshai" (Eprom version) is correct for 614R-A and 614R-B. I also had a Gateway to Apshai Eprom version and later bought a ROM version (kept the ROM version/pcb and changed the Eprom version/pcb to my likes by removing the Eproms and burning a different game on them)...

Forgive my ignorance but what is MD5? I know what a checksum is, just not MD5. I have saved all three EPROMs to a floppy as bin files. Now, how do I get them posted here? I have a SIO2USB device running Mydos 4.53, and APE for Windows. DavidMil Quote Link to comment Share on other sites More sharing options...
