    In CiderPress, creating a 32MB volume (labeled "largest ProDOS volume") creates a 65535-block file, because that's the ProDOS limit. Partition managers will likely round up to the nearest megabyte, allocating space for 65536 blocks. I figured it's
    safer to copy a 65535-block volume into a 65536-block space than the other way around, so went with the smaller size.

    You can create a 65536-block volume in CiderPress by entering the size manually.

    Has anyone studied the RamFAST ROM content to see what changed between versions?

    CSA2FAQ mentions a bug in the restore action of 3.01e which will trash your partition table.
    I didn’t find anything else with google.

    I hope GEnie RT may have more info with announcements of new versions being available but I don’t have access to this content myself.

    I have received some source code but it may not be the latest. I don’t see anything about 3.01f in it.

    I would be interested in that as well. Particularly what type of code is stored in 'U16' on the RamFAST revision C, and was v2.01 the
    final version? (the card has two ROM sockets).

    In terms of important updates, I do remember 3.00L or higher (for both cards) was necessary for working with removable media.

    Only 1 byte of data changed between 3.01e and 3.01f. It corrected a bug
    in with the built-in RamFAST utilities 'restore' option for tape backups.
