 ## Caveats

-Due to the dearth of documentation on the DCD protocol (see below), the protocol only implements the commands whose formats are known, namely read, write, and device identification.  Responses to other commands are faked.  Fortunately, this seems to be enough for the device to function properly, including formatting.
+Due to the dearth of documentation on the DCD protocol, the protocol only implements the commands whose formats are known, namely read, write, and device identification.  Responses to other commands are faked.  Fortunately, this seems to be enough for the device to function properly, including formatting.

 The disk drive interface relies on use of the phase lines to read and write one-bit registers.  Because the PIC16F1825 firmware mimics the register set in code instead of programmable logic, it has a response time that is, in the worst case, approximately one microsecond.  This may interfere with the ability of faster Macs to detect it, though it is not known to do so at this point.  The PIC16F1704 firmware mimics the register set in logic and responds in effect instantly.

-Certain Macs may have a limitation imposed by their ROM on the number of DCDs they support.

 ## Technical Details

+### Building Firmware
+
+Building the firmware requires Microchip MPASM, which is included with their development environment, MPLAB.  Note that you **must** use MPLAB X version 5.35 or earlier or MPLAB 8 as later versions of MPLAB X have removed MPASM.
+
+
 ### MMC Card Format

 The MMC card must have an MBR (Master Boot Record) aka DOS-type partition table with up to four primary partitions of type 0xAF (HFS).  Extended partitions are not supported.

 ### DCD (Directly Connected Disks) Protocol

-#### Details Missing or Inaccurate in the [May 1985 DCD Document](http://bitsavers.trailing-edge.com/pdf/apple/disk/hd20/Directly_Connected_Disks_Specification_1.2a_May85.pdf)
-
-* The sync byte, in either direction, is always 0xAA, 0x96 is not used.
-* When Mac is transmitting a command, the sync byte is followed by two more raw IWM bytes before the 7-to-8 groups begin. DCD transmits only a sync byte and does not transmit these extra bytes.
-   * The first is 0x80 plus the number of 7-to-8 groups in the command being transmitted by Mac.
-   * The second is 0x80 plus the number of 7-to-8 groups that Mac expects to receive in response.
-* The holdoff protocol is completely different than specified.
-   * In either direction, a holdoff is initiated by Mac transitioning from state 1 to state 0.
-   * If Mac is transmitting, it will finish the 7-to-8 group that it has begun transmitting. This data is valid.
-   * If DCD is transmitting, it must finish the 7-to-8 group that it has begun transmitting. This data will be treated by Mac as valid.
-   * A holdoff is ended by Mac transitioning from state 0 to state 1. There is no negotiation.
-   * If Mac is transmitting and WR is high at the end of the last byte transmitted before holdoff, it will transition WR from high to low right before transitioning back to state 1.
-   * Mac will resume transmission with an 0xAA byte, followed by the bytes in the next group after the group where the holdoff began.
-   * DCD must resume transmission with an 0xAA byte, followed by the bytes in the next group after the group where the holdoff began.
-* The Controller Status (command 0x03) block is slightly different than specified.
-   * The total size of the Controller Status block is 336 bytes, not 532 bytes.
-      * 336 bytes of data, 6 byte header, checksum byte == 343 bytes == 49 7-to-8 groups
-   * The Icon field contains a 32x32 icon as a 1-bit bitmap, followed by its 32x32 mask, also as a 1-bit bitmap, for a total of 256 bytes.
-      * The format of the bitmaps is identical to that of ICON resources.
-   * The Filler field is replaced by a 16-byte Pascal string (first byte is length) that determines what appears in the "Where:" field of the Get Info dialog box.
-* The checksum byte is chosen such that all data bytes in all 7-to-8 groups (not including the sync byte or the command/response length IWM bytes) sum to 0 modulo 256.
-
-
-#### Details Out of Scope for DCD Documentation But Useful to Know
-
-* The IWM transmits and receives MSB first and the MSB is always set; the chip uses this for timing.
-* The IWM transmits at its "fast" speed, 47/96 MHz, or approximately 489.58 Kbps, data cell width 2.043 us.
-* The IWM's output (on WR pin) is in NRZI format (inversion == 1, no inversion == 0).
-* The IWM's input (on RD pin) detects only falling edges.
-
-
-#### Beyond
-
-Other details about the protocol at the signal level and the read, write, and controller status commands are accurately reported by the [May 1985 document](http://bitsavers.trailing-edge.com/pdf/apple/disk/hd20/Directly_Connected_Disks_Specification_1.2a_May85.pdf); other commands are unknown to me, but hopefully this information will be useful to anyone in the future who wishes to implement DCD.

+# Internal
+
+This is cheesey's board for use of TashTwenty internally to a Plus or a 512ke (as far as I know).  It interposes between the IWM and the logic board, and reroutes things so that the back floppy port on the computer still works.
+
+Note that installing this requires the IWM on your Plus/512ke to be socketed!  While building the board is easy, desoldering the IWM from the logic board can be an exercise in applied pain, especially if the solder is crunchy.  Caveat haxor.
+
+To build it, you will need:
+
+* A 74HCT04, a 74HCT02 and a TashTwenty
+* A MCP1700-3302E voltage regulator (other 3.3V regulators might do if the pinout is the same)
+* An SD card socket.  I used a cheap breakout I got online.  Be aware that the Adafruit micro SD breakout boards have a weird pinout and won't work: the pins on this board are in the same order as they are on the surface mount sockets (and thus on the card themselves), please use one with a boring pinout.
+* A handful of capacitors, resistors and LEDs.
+* A socket for the IWM and some SIL header rows to 
+
+The PCB is designed to be easy to build.  The component values are marked on the board, I wanted this to feel like a kit to build.  Some notes:
+
+* The SIL headers sticking down from the board go into the leftmost set of DIP holes, the socket on top for the IWM (or the IWM soldered if you're feeling really brave) goes on the right.  Sorry this is unclear on the board; I couldn't work out how to make it clearer.
+* Install the SIL headers before the socket or you will hate your life.  Use a DIP socket to hold them in place or you will find that the board won't plug into the DIP socket.
+* The LEDs and the resistors next to them (R8-11) are optional.  R1-R7 are *not* optional.
+* Do check again that your SD card socket pinout is correct
+
+Notes on installation:
+
+* You may wish to use low-profile IC sockets and low-profile SIL pins if you can: mine only just fits under the metal shielding
+* Putting a self-adhesive rubber bumper under the board where it hovers over other chips might well help with keeping everything in place.
