I'm afraid I can't take that much credit for it; the system was in remarkably
good shape when I received it, and all I had to do was verify that the voltages
put out by the power supply were within tolerance and fire it up. The most work
went into replacing the rubber belts in the old QIC tape cartridges holding the
software and backups. Having all the documentation that spells out the magic
incantations to boot the system helps too.
I still have one remaining issue, and that is that when I connect the system to
my network, it works (I can ping both ways), but the OS becomes unstable, and
usually crashes within a few minutes. Perhaps it has a problem with jumbo
packets or something like that.

Fantastic video and work! The immense boards and 3D molecular software are
very impressive!

Ardent Titan with some interesting software on it – the bundled version of
MATLAB, and BIOGRAF, a molecular modeling application – I decided to make a
short video about this system in which I show the hardware and demonstrate some
of the software: https://youtu.be/tMSnnt3iFz0

(as in a Cray-like architecture) and a graphics engine on the same backplane,
and was the highest-performing graphics supercomputer for a short while. In the
end, however, a longer than planned time to market and a forced merger with
Stellar Computer caused the premature demise of the company.

which is one of the reasons the Titan was the only computer ever to come with
MATLAB as part of its bundled software. As I found out later – after creating
this video – the version of MATLAB on the Titan was unique, because it included
a “render” command, which would plot a 3D surface using the Doré graphics
library. On other platforms, MATLAB could only render mesh plots. It wasn’t
until 1992 that the mainstream version of MATLAB gained 3D surface rendering.

describes how the Titan was used to create a video of a vibrating L-shaped
membrane. With a little help from Cleve, I’m trying to recreate this video. A
first effort – which isn’t quite right yet – can be seen here:
