RX02 Emulator v1.9d

Updated Digikey BOM part number replace HCT14 with AHCT14

RX02 Emulator v1.9c

Updated BOM .csv file to add Manufacturer/Part Number, and DigiKey part number columns. This allows for BOM import function on the DigiKey website to just drag and drop the BOM file to create a DigiKey BOM for parts purchase.

RX02 Emulator v1.9b

Change all line endings from LF (unix) with a final EOL CR/LF (inserted by Arduino IDE) to strictly CR/LF line endings. IDE starting v1.8.8 (it seems) is really picky about line endings and does not preserve strict unix LF line endings. Changing files to CR/LF windows text format resolves this. Sigh...

RX02 Emulator v1.9a

Minor update to TRUE/FALSE definition logic for v1.8.8 Arduino IDE compatibility

RX02 Emulator v1.9

Rearrange directory structure to put Arduino code under source directory; add documentation directory, and disk_images directory.

Fix handling of unmounted unit to not create a spurious filename 'NONE'.

RX02 Emulator v1.8

Add capability for debug window baud rates of 500Kb/1Mb/2Mb for Arduino IDE 1.8.2 or later.
Default debug window baud rate remains at 250Kb unless changed explicitly in the main program code.
No functionality change from v1.7 in any other way.

RX02 Emulator v1.7

Documentation update, add INSTALL section to README file, covering complete ArduinoIDE setup.
Additional updates on successful testing on various configurations (like QBUS RXV21, etc).
Syntax updates in code to remove spurious compiler warnings.
Optional use of TimeLib library to allow timestamping of file accesses on the SD card.

RX02 Emulator v1.6

Added processing of .RX1/.RX2 file extensions to auto-detect media size of SD/DD respectively.

RX02 Emulator v1.5

Update checks on mounting files; check that mounted files are exactly SD or DD sized, else they will not be made 'ready'. Add e/f/r commands to zero-extend/truncate files to SD or DD size; r command to remove a file.

RX02 Emulator v1.4

Tested and working with RX02/RX211 interface on a PDP-11/44 under RT-11v5.7 and XXDPv2, and on a PDP-8m RX02/RX28 with OS8v3d, and RX01/RX8E using standalone diagnostics.

Changed RUN signal processing from interrupt-driven rising edge to polled for 5-10% better r/w performance.
