| Posted by: micheledipaola on 2024-08-09 08:08:36 Hey, Hey there! I just found one of these in a Color Classic 2 I got from Japan. I noticed you have the 1.1.2 chip there. Mine has the 1.1.1. Is there a way to make a duplicate of that socketed ROM possibly? And also wondering if the Color Classic version might work with an SE/30?I am on holiday until the end of next week. Then once home I guess it’s finally time to unpack that eprom reader/writer and see how it works… | |
| Posted by: JT737 on 2024-08-10 14:24:54 @chiptripper -Unfortunately, I sold my Interware CV-40-40 booster a few years back. Otherwise, I'd be happy to make a copy of the firmware for you! | |
| Posted by: mousehouse on 2024-08-12 13:11:41 Mine has a 1.1.2 chip as well. Happy to create a bin from the ROM but need to get my 866 reader installed and figure out how to do this again 😄 Hope you’re not in a rush… | |
Posted by: micheledipaola on 2024-08-20 01:43:27Hey,Back home and reading the messages on a wider screen I just figured out that your message @nottomhanks was not for me 😀 my ROM is 1.1.1 as shown in the pics I posted years ago... If anyone else ( @mousehouse ?) is able to dump the content of a 1.1.2 ROM , that will be useful for me too, I guess! | |

Does anyone here happen to know that information? | |

Happy to create a bin from the ROM but need to get my 866 reader installed and figure out how to do this again 😄Do you think it's possible to plug in the CL 40-40 into Bolle's adapter? Or will that cause major problems? It would be awesome if you could use this with an SE/30 to speed it up!! | |
Posted by: patatas on 2024-10-18 11:42:15@micheledipaola -I was gonna say, that looks like a card for one of the LC's! I have a CV 40-40 Interware Booster myself; somewhere I have the cache card for it. But yea, that connector on the back of it is indeed a cache memory connector. View attachment 36446Any chance we can get a copy of the v1.1.2 firmware as I have v1.1.1 ? | |
| Posted by: JT737 on 2024-10-26 08:57:24 @patatas -Unfortunately, I got rid of the card a few years ago now. Although I might have copied the firmware; I'll check when I get back home. | |
| Posted by: JT737 on 2024-10-26 11:59:24 @patatas -Unfortunately, I indeed did not think to back up the firmware for the CV card before I sold it :-( | |
| Posted by: patatas on 2024-11-02 14:00:57 no worries..will continue the hunt. thanks | |
| Posted by: mousehouse on 2024-11-04 04:23:50 I have a CV40 that I can dump the ROM from. Is there a app that allows me to do that when the card is installed in my Mac? I'd prefer that over extracting the EEPROM from the brittle plastic socket... | |
| Posted by: zigzagjoe on 2024-11-04 07:30:18 It's not known where the CV40 maps its ROM nor how it's wired, so you'd need to dump the ROM externally. | |
Posted by: mousehouse on 2024-11-10 11:37:27It's not known where the CV40 maps its ROM nor how it's wired, so you'd need to dump the ROM externally.Ok, I get that! Will need to dig up my TL866 and get it up and running again. You’re not in a rush I hope 😄 | |
Posted by: zigzagjoe on 2024-11-10 11:47:01Ok, I get that! Will need to dig up my TL866 and get it up and running again. You’re not in a rush I hope 😄No rush, I think - I'm not actually the one that needs it 🙂 | |
| Posted by: mousehouse on 2024-11-11 00:19:11 OK - step 1 completed. Managed to get the EEPROM off witghout destroying the card... Does anybody know the EEPROM type used? Mine still has the sticker on it that I would like to keep on. Forgot how to use Xgpro to check the type, sorry... | |
| Posted by: mousehouse on 2024-11-11 00:30:56 Updates... I messed around a bit and read EEPROM ID 0x2005 back from it. Could be an ST 27C1001. Attached the 128KB ROM dump... let me know if this works! | |
Posted by: Daniël on 2024-11-11 00:33:27Updates... I messed around a bit and read EEPROM ID 0x2005 back from it. Could be an ST 27C1001. If you read it with ID check on and got no errors, then it should indeed be that chip. A 27C1001/27C010 (same ROM, different numbering system) would make sense, I can't imagine it'd be much larger than that. | |
| Posted by: mousehouse on 2024-11-11 00:45:51 Yes, came back from the ID check like that. Very happy they used something super standard 😂. Now it up to @patatas to test! | |
| Posted by: zigzagjoe on 2024-11-11 06:38:57 Dump looks good, and not scrambled at that. Looks like it probably overrides the initial SP/PC loaded by the 040 at boot? There's a plausible SP and PC, that PC would indicate the ROM is mapped at 0x52600000 and points to a routine that immediately plays with cache and MMU registers (expected for an 040). In a bit of code further along, it also checks for the IIci ROM checksum. Not quite clear what happens when not present.  Further discussion on this card and any reverse engineering probably should take place in another topic, however 🙂 | |
