Yes, for Transputer-only I am using Helios on the
PowerXplorer (PPCs idle in this case) and with PARIX,
the Transputers are doing the networking part whereas
the PPCs execute the user code.

OK, so I am crossinf my fingers, that you will
find some time in the future and the S4 within
your IPX is a good point to start at!

In an emergency I can supply images of the EPROMS I guess.
The first test is restoring the IPX and if your BBK-S4
can be accessed you are a good step further. My first
test here alway is to issue a...

is. In my case:
slot 0 - NO VALID SBUS DEVICESBus
slot 1 - NO VALID SBUS DEVICESBus
slot 2 - NO VALID SBUS DEVICESBus
slot 3 - 'CWA: BBKS4' No link available for checking versio

Well, one cable will be enough to start with. I am
normally using ony one entry into my PowerXplorer-setup.
My biggest test run was with a mesh of 8 Trapus/PPCs.

Well, I guess, these are very rare and although I have
got a preview chip (i.e. really only the chip without
housing, pins etc.), I also have never seen any
documentation or even software for the T9000...
Best regards and good luck,
