 <B>tu58em</B> was originally based on the 1984 Dan Ts'o tu58 program, but has been almost completely rewritten to make it compile error free, improve the program flow, and add new functionality. It has been compiled within the CYGWIN environment, and will run either within a CYGWIN window or an MSDOS command window with the associated cygwin1.dll helper file. <B>tu58em</B> has been tested under Win2K, WinXPsp3, and Win7sp1. <B>tu58em</B> has compiled error free under Linux (Ubuntu 12.02LTS) but has not yet been rigorously tested in that environment.
 
-Each emulated .dsk image file is exactly 256KB (512 blocks of 512 bytes) of data and is a byte-for-byte image of the data on a TU-58 cartridge tape. As currently configured <B>tu58em</B> will support up to 8 drives per controller as DD0: to DD7: (altho this is easily changed in the source).
+Each emulated .dsk image file is exactly 256KB (512 blocks of 512 bytes) of data and is a byte-for-byte image of the data on a TU-58 cartridge tape. As currently configured <B>tu58em</B> will support up to 8 drives per controller as DD0: to DD7: (altho this is easily changed in the source). <B>tu58em</B> will support disk image files as large as the TU58 protocol allows (ie, 32MB, or 64K 512B blocks); however most standard DEC operating system drivers restrict TU58 drives to 256KB each. The DEC driver must be patched to allow for larger than 256KB disk images.
 
 <B>tu58em</B> has been tested using both native RS232 serial COM ports and serial ports emulated thru USB serial adapters.
 
 Note: <B>tu58em</B> is compiled using the CYGWIN serial interface library routines (ie, termios.h) and is the preferred version that should be used. <B>tu58ew</B> bypasses the CYGWIN serial interface layer and makes direct Windows serial comm routine calls. This version was done early on because of deficiencies in the CYGWIN serial library. However, the required features are now present so in reality <B>tu58ew</B> should be considered deprecated.
 
+The latest version (as of 1.4m) integrates Mark Blair's updates for VAX mode operation (for VAX-730 microcode boot support) and background mode.
+
+A cygwin folder with a precompiled 32b cygwin executable (tu58em.exe) is included for those without cygwin environment access. Under Windows, just open a standard CMD.EXE window, change to the cygwin folder, and run the <B>tu58em.exe</B> executable as a command line program.
