Disk Images
Here are the disk images to use with the Emulator or a Cortex.  These are probably the only copies in existence so I hope they don't infringe upon any copyright issues. 
EPROM Source
The entire Cortex EPROM source code files, along with an Assembler & Linker to build an EPROM image identical to the original.  Now you can customise your Cortex firmware!
MDEX Disk Utility
A utility used to extract MDEX files from an MDEX Disk Image.  This was used to extract and create the SAFORMAT.cas and DISKIMG.cas used by the PC Comms Utility.
Cortex EPROMs
Images of Cortex Basic and Fig Forth EPROMS.  Contains both individual EPROM images as well as combined images for use with the Emulator.
Cortex Emulator
This contains the Windows Cortex Emulator and an image of the original EPROM firmware.  Simply unzip these two files into a folder and you have a Cortex.

This contains the Source Code.  It is a ZIP of the entire Embarcadero C++ Builder XE2 Project.
PC Comms Utility
All you need is this PC utility and a simple 3-wire cable to be able to recreate actual disk images on the Cortex. 

It can also be used in place of a cassette recorder for saving and loading BASIC/Machine Code programs if you don't have the TMS9909 disk interface.  The cassette images are compatible with the Emulator.

See the README.pdf for full details.
