testo tratto dalla Homepage 1541 Ultimate:

• Last firmware version: 2.0RC5 is now downloadable from the download page.

• Ultimate-II sources released!

You can access them through http://svn2.xp-dev.com/svn/1541UltimateII/.

For those who know how to use SVN, you can do a checkout to create a local working copy by typing:

svn co http://svn2.xp-dev.com/svn/1541UltimateII/trunk

in an empty directory. I am working on a short manual, and on access to the tools needed to build the project. This time, the FPGA sources have been released as well. ;-)

General Info:

• Firmware written primarily for the DivIDE interface, maybe for others in future.
• Inspired by our (Phoenix & LaesQ) old ‘backbone’ project + inspiration from +D
• Works with HDD/CD-ROM/ZIP/LS120 (LS120 can access 720KB and 1.44MB floppies)
• Uses drivers to access filesystems (either in RAM or ROM)
• Provides new BASIC commands
• Will provide RST 8 hooks for user-land apps
• Supports IM2 loading/saving (K3L’s FA part)
• Drivers give access to the filesystem, and provide specific emulation hooks in certain cases (TRDOS, .TAP, etc)
• There’s a device/filesystem abstraction layer, which means that BASIC or user-land programs don’t need to know anything about the underlying filesystem/device (ie, you use the same BASIC commands for all filesystems, FAT/ISO/TRD/etc)
• Will allow up to 4 virtual drives for disk images (.trd/etc)
• Filesystems are mapped acording to type: hd*, fd*, cd*, vd*, td*
• FAT12/16/32 driver built-in ROM, other drivers loaded from boot filesystem on demand. (on this preview version, there was still room so TRDOS filesystem is in ROM too)
  Does not need a system file to work, common BASIC commands and FAT driver on ROM, system file loaded from boot filesystem will have additional commands, etc.
• … more stuff which I prolly forgot

Ho trovato nei miei backup di Amiga un’archivio contenente alcune Roms dei Firmware per i vecchi “copiatori/backup” di Super Nintendo e Megadrive.

Cosa c’e’ dentro l’archivio:

• Super Wildcard v2.7 (snes)
• Magicom v3.2h (snes)
• Super Magic Drive v4.1-a (megadrive)

Questa versione Beta del firmware per l’interfaccia 1541-III supporta la modalita’ JiffyDos.

Il JiffyDos e’ un fastloader che dimezza i caricamenti dal floppy disk del 50%.

Questa versione del firmware è ancora in fase di sviluppo, ci sono alcuni bug che verranno risolti con il passare del tempo, questa versione non supporta la simulazione Audio del caricamento tracce del Floppy Drive.
