Working Ardent Titan on Youtube

[Camiel Vanderhoeven]

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!

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.

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.

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: https://youtu.be/-XeabDqRAG8
