-# micro-sci-a2-controller
+# Micro-SCI / Franklin Apple ][ Floppy Drive Controller
 
 This is a clone of the Micro-SCI / Franklin floppy drive controller.
 
 v0.1 is a direct clone, reverse-engineered from a Micro-SCI board.  It was cross-checked with a Franklin-branded board, as well as the (belatedly discovered) official Franklin schematic (included in doc/service_and_schematics.pdf)
 
-Since it is a faithful clone, it requires a 2708 EPROM (or a different EPROM with a 2708 adaptor).  A board slightly revised to use a 2716/2732 is available on the 2716 git branch.
+v0.2 has the following enhancements over the original design:
+
+* the 2708 EPROM has been replaced with a more-common 2716/2732 EPROM
+* decoupling capacitors have been added
+* footprints for all capacitors and resistors have been modernized
+* firmware EPROM bank selection jumpers replaced with a DIP switch
+* obsolete MPS-U51 transistor replaced with modern equivalent
+* clearly-marked calibration test points have been added
+* ground pours used to increase operational stability
+* support for using Floppy Emu in dual-drive emulation mode with one cable
 
 Firmware images can be built via the Makefile in the firmware subdirectory.  The build framework requires cc65.

-## Jumper block
+## EPROM bank select switches (J4)
 
-* 1-2 and 3-4: controller test firmware (0x0000)
-* 1-2: 16-sector firmware (0x0100)
-* 3-4: 13-sector firmware (0x0200)
-* empty: firmware "put jumpers here" splash screen (0x0300)
+* 1:off 2:off - firmware "put jumpers here" splash screen (0x0300)
+* 1:off 2: on - 13-sector firmware (0x0200)
+* 1: on 2:off - 16-sector firmware (0x0100)
+* 1: on 2: on - controller test firmware (0x0000)
+
+## Calibration procedure
+
+* set J4 to on/on ("controller test firmware")
+* connect oscilloscope to TP1
+* start machine
+* execute "call 50688"
+* execute "AAW" (and immediately hit ESC)
+* adjust R1 until waveform period is 5.4 microseconds
+* connect oscilloscope to TP2
+* execute "99W" (and immediately hit ESX)
+* adjust R2 until waveform period is 3.8 microseconds
+* card is now calibrated, power off machine and set J4 to "16-sector firmware"
+
+## Construction notes
+
+* J3 can be omitted if this controller is used with a FloppyEmu
+* All discrete logic ICs (except U15, the 74LS373) can be CMOS (74ACT, 74HCT).  As is unfortunately usual with the Apple ][, U15 must be LS due to timing issues.
+* if CMOS logic is used, then Q1/R6/R7 can be omitted -- the entire logic array can remain powered up at all times.  Connect pads 1 and 3 on the Q1 footprint.
