  1. Joan Dow comments on 3.1 ROM development: "I'm trying to think back whether Commodore ever released 3.1 at all. I believe the release was interrupted by the bankruptcy. The development cycle never completed since each of the last three builds shown developers had problems on some system."
  2. Ross Vumbaca comments on the v40.60 ROM: "I saved this [his CD32's Kickstart 3.1] ROM to a file, and used it in an emulator ("soft-kicked"). It produces a normal "Disk insert screen" but for some reason, the palette screen would not appear in a CD32. The second 512kb of ROM (since it is a 1MB ROM) is supposedly stored at address: $E00000 - $E80000. The extra ROM contains CD32 specifics: boot-up screen, boot-up sound, CD player/locality code, debox.library, cd.device, and cdtv.device."
  3. The 3.1 ROM contains at least two improvements over the 3.0 ROM: minor bug fixes, and small RTG improvements.
  4. There were two releases of 3.1: VillageTronic obtained permission to release it to all their PicassoII owners back in 1994 (amidst some debate as to whether they really had this permission or not). Then, the official release occured sometime after this.
  5. There are different OS 3.1 Kickstart versions as follows:

     Amiga Model   Version              P/N(s)
     CD32          (40.56/40.58/40.60)  391640-02/ ? / ?
     500/600/2000  (40.63)              ?
     A1200         (40.68)              391773-01, 391774-01
     A3000/3000T   (40.68)              ?
     A4000         (40.68)              ?
     A4000T        (40.70)              391657-01, 391658-01
     CD1200        (40.70)              ?

    These versions reflect slightly different scsi.devices in use for stability reasons as Olaf Barthel explains:
  6. "It's not the version number that counts. It's the type of machine the ROM was created for. The A4000T 3.1 ROM, version 40.70, does not contain any driver firmware to control the A3000 SCSI hardware. That's what you'll find only in the A3000 ROM. The last few OS revisions following 40.65 would contain only changes made to the SCSI (and the IDE) drivers. Somehow, some changes made it into the A3000 SCSI driver for 40.70 which for some people caused trouble with their SCSI devices. The driver in 40.68 did not trigger the same problems, which is why, eventually, 40.68 shipped instead of 40.70. Some of the 40.70 ROMs shipped to customers who didn't have any problems at all with the SCSI driver."

    Klaus Burkert provides further information in this regard:

    "There was 40.70 for A3000 and A4000 when VillageTronic initially released OS 3.1. But those versions had problems with some accelerator boards and with some hard drives, thus the step back to 40.68 was taken, the same reason is responsible for "only" 40.63 on the 16 bit systems. All this happened more than three years ago..."

    "They [the Kickstart versions] are not interchangeable—at least not with a fully working featureset. If you are ever told otherwise, the person/company either doesn't know or is lying."

  7. Markus Bieler notes another difference in v40.70: "The Kickstart for the A4000T does not contain the workbench.library. It was removed from the ROM to the Workbench disk (in the LIBS: directory), to make room for the A4091 SCSI support. So there is a small difference between the disks supplied with the A4000T and the disks for the other OS packages." M.C. Battilana notes that: "Not in our version, which includes workbench.library on both bootable disks (1/6 = Install disk, 2/6 = System). The A-4000T ROM is not the only one to be without workbench.library, as our 3.X ROM also does not include it, for the same reasons (the space was needed for other improvements). Our Classic Support 3.1 Workbench disk set (and the Compact Flash version) works on all Amigas, including A-4000Ts and those with 3.X ROM."
  8. 3.1 ROM Chip part number for the CD32 (40.56) is 391640-02.
