CFFA3000 firmware 3.1 released

[David Schmidt <schmidtd@my-deja.com>]

Rich Dreher and Dave The Firmware Guy (not me) have released version 3.1 
of the CFFA3000 firmware.  You can download it here:

http://dreher.net/?s=projects/CFforAppleII&c=projects/CFforAppleII/downloads.php

This release includes support for folders (subdirectories) on CF and USB 
media.  Other interesting tidbits from the readme:

== How to Upgrade ==

Put both CFFA.BIN and CFFA.XSV onto a Compact Flash card (NOTE: You 
cannot use a USB flash drive for this).
Insert the CF card into the CFFA3000 and enter the CFFA3000 menus.
The CFFA3000 will offer to upgrade to v3.1, and after that it will offer 
to update the CPLD to version 6.

== Folders ==

Now allows folders on FAT volumes, making it easier to organize a large 
number of disk image files. Folder names will appear with a trailing '/'.
Press <Return> on a folder to navigate into the folder. Press '-' (or 
use <Ctrl>X, or <Apple>UpArrow) to move back up to a parent folder.

The firmware will remember the current folder for both the CF and USB 
media. The path shows up at the top left, above "Items:" to separate the 
current-folder lines from the contents below. The current folder always 
resets to the top level when you insert the USB drive or CF card.

You can use folders inside folders, up to 8 levels deep.  The item list 
can only show up to 255 items in a particular folder; if you have more 
files than that, please break them up into sub-folders.

== Assignments Screens ==

<Crtl>B: Now reboots the slot for which you're making assignments.
Disk II assignments: Comma and Period rotate among the panes.  SmartPort 
Assignments: When there are more configured images than the "SmartPort 
Devices" setting, the extra ones appear at the bottom of the right-hand 
column, marked with '*', and if you highlight one you'll see 
"(Unavailable - SmartPort full)".

Pressing '-' in a right-side pane deletes an assignment (like Delete / 
Control-D).

<Apple>Space in the right-hand column toggles between SmartPort and Disk 
II assignments.
Apple IIgs only: <Shift>Tab cycles backwards through the panes (like 
Comma does).

== Menus ==

When a menu item for an adjustable setting it highlighted, '<' and '>' 
indicators now show which ways the menu item can be adjusted.

The "Quit" or "Boot" menu item now lets you choose which slot to boot 
from, using the Left and Right arrows.
    Quit: Without Booting
    Boot: Slot N
    Boot: Slot N (Continue)
    Boot: Reboot

In the "Other Settings" menu, replaced "Delay for Menu Key" setting with 
"Menu at Boot" which may select from "Always", 0.1s..0.2s....up to 25 
seconds.
If you choose "Menu at Boot: Always" and your Apple II finds the 
CFFA3000 at startup, you'll be able to press Return to continue booting 
the CFFA3000, or use the arrow keys to choose another slot.

The menus use some MouseText characters (when running on an Apple IIgs 
or an Apple //e enhanced).
If you don't want to use MouseText, you can turn on DIP Switch 2.

== Performance ==

The CFFA3000 does read-ahead caching from USB or CF, while the Apple II 
is busy copying the previous block. This requires CPLD v6. Which version 
you have may be checked any time by going into the menu and selecting 
the "About" menu. The CPLD version is displayed near the top of the screen.

Various speed improvements in the 6502 and 65816 firmware including 
faster coordination with the CFFA3000's microcontroller, and faster 
entry for ProDOS and SmartPort calls to the card.

== New DIP Switches ==

DIP Switch 1: Flip on if your Apple II or Apple II+ has a "lowercase 
chip" to allow the CFFA3000 to display lowercase letters.
DIP Switch 2: Flip on if you don't want to use MouseText.
DIP Switch 4: Flip on if you are using an Apple III. Since Apple III 
requires the GS DIP Switch to be on, this lets the CFFA3000 know whether 
it must use the 6502 firmware or the 65816 firmware.

Note 1: To use the CFFA3000 on an Apple III, you must turn on both the 
GS DIP Switch 7 and DIP Switch 4.
Note 2: The firmware will optimize for the GS's 65816 when the GS DIP 
Switch 7 is on and Switch 4 is off.

== Compatibility ==

The end of the Disk II slot ROM now more closely resembles a real Disk 
II.  This makes at least one version of Karateka work.
