Extended kickstart 2.0 (A690)
Out of curiosity has anyone dumped and supplied WinUAE with the A690 (A570 prototype) Extended Kickstart ROM?
It is physically labelled "391298-01 V1.0 Copyright @1991 CBM C480" https://bigbookofamigahardware.com/b...a690_1_big.jpg But when the A690 boots the version number displayed in the bottom LHS of the screen is 2.0 https://rclassiccomputers.com/wp-con...pe_repair4.png The known Extended ROMs print their number in the same place 1.0, 2.7 (2.07) and 2.30 but I can't find anything about the A690 ROM. Not that it really matters as I'm fairly sure A690 owners can use 2.30 |

I've no idea if this Extended ROM is already widely available. I'd never seen it before.
After a quick search I've come across one and I've put it into the zone. (assuming that is allowed? It is not a version provided by any commercial vendor) It doesn't load into Romsplit by Doobrey because the checksum isn't a match, which could be that no-one has seen this before? It is similar but significantly different enough when compared to v1.0, 2.07 & 2.30 for me to believe this is a real v2.0 dump. Last edited by alexh; 17 March 2021 at 00:23. |

Doobrey has accepted the ROM for inclusion into ROMsplit.
Several people have commented that the A690 ROM should have a different bookmark.device which is battery backed up RAM compared to the A570 which has an EEPROM. |
