PC Transputer Emulator Version 2.2.

[Gavin Crate]

I've uploaded a new PC Transputer Emulator Version 2.2, which fixes a
memory accessing bug if trying to read or write outside the external
2Mbyte memory address space.

Another bug identified by Mike (see original CST thread below for
reported bug). Minix now runs and correctly reports 2Mbytes of memory.
Cool!

The new version can be found on my website:

The new files (Emulator Files & Alternative Builds) are attached at
the bottom of the installation Instructions page.

Whilst the Minix boot monitor appears to run correctly, the booting of
the actual Minix kernel seems to hang, as shown in the screen dump
below:

Booting root transputer...ok

Secondary bootstrap entered.
Free mem starts at 800007bc

It hangs! Hmm? If should display the following as captured on a real
