Excuse me but the file "machinec" seems to be truncated as the simulator waits forever at the third chunk.
I don't know what happened at you
I tested it on real Enterprise, EP32 1.20 in tape and disk mode, ep128emu 2.0.5.1 in tape, disk and fileio mode. All times works fine for me!
I download the file from this site, and also works.
The correct file sizes:
MACHINEC.BAS 243 bytes
MACHINEC 6322 bytes
Now I upload .TAP file version for the ep128emu.
On the other side in the instructions is referenced a third file named "Demonstrate" that is missing altough is't inpmportant.
I copied these files from the original tape, and it is not contain any other file. I have two of this original tape, and checked both, but not found any more file.
