This (free) program emulates a combination of an Inmos T414 transputer (with 2M RAM) and the standard iserver host interface program. It runs on Macintoshes. (Both 68k and PowerPC based ones.) It needs 2.5 MBytes of memory.
The emulator has been tested on a PowerMac 6100, a IIci, an LCII, a quadra 650 and a powerbook 165.
A "Hello World" binary is included as an example for testing the emulator on other machines.
The emulator runs single transputer binaries as though invoked using "iserver -se -sb bootfile.btl". The "-se" stop-on-error flag may be turned off using the options menu. The other options menu entry allows you to enable instruction profiling, which counts how many instructions of each kind are executed and saves the result to a file called "profile".
This is the first release and will have many new bugs for you to discover. Bugs may be reported to J.C.Highfield@lut.ac.uk until the end of September 1994. Initial bug reports should take the form of a summary of the machine the emulator is being run on, the compiler the transputer binary was generated by and whatever the binary does. Since bugs in an emulator can take a long time to track down, with some recent ones appearing after the emulator had executed 100 million instructions, then to actually solve a bug report I would probably need the binary and any data files it uses. Arithmetic bugs etc. would however be much simpler to solve than this, with a one line example program being quite adequate.
If anyone has suggestions for improvements then please send them along - I will try to include them. One feature I already intend to alter is that the emulator does not currently update its window after being obscured by another window.
