Tools (Tape / Disk)

Below are the tools which have been developed and contributed through the years. A replacement for them is available on the CODEX (nosutils) . A windows installer is available on the Utilities page which contains pre-built versions of all of them.

Convert a Host-OS file to Tape (.tap)

You need two tools to do this, both of which are provided in the dtcyber distribution: tools/atod/atod, which converts from ASCII to Display Code, and tools/nosicreate/NosICreate, which converts a display code file into a NOS I-format tape.

You need to compile both yourself (they aren't compiled by the Makefile) from the source codes in the same directories (see Note 2 below for changes you'll need to make before compiling on UNIX- or Linux-derived systems; for Windows, you need make no changes). For convenience, place both binaries in the same directory. Here is the procedure on how to use them (I'm assuming you're using a UNIX variant host system; if you're using Windows, just reverse the slashes):

  1. Change to the distribution directory.
  2. ./atod yourfile ir0001 (See Note 1 below.)
  3. ./NosICreate yourtapefile.tap

This will produce a .tap file which you may now manipulate with dtcyber.

Note 1: You must specify an output file of ir0001.
Note 2: To compile atod and NosICreate under Linux, in each of the files atod.c and NosICreate.c, change the typedef signed long i32; to typedef signed int i32;. Also, change the typedef unsigned long u32; to typedef unsigned int u32;. And typedef int64 i64; must get changed to typedef unsigned long long int i64; and finally, change typedef unsigned int64 u64; to typedef unsigned long long int u64;.
