Instead of writing these enormous articles, that take forever to finish and no one reads, I decided to write shorter pieces on just one topic. Hopefully it will not be that taxing on your patience and I can crank out material more frequently.
The other reason to grab the pen keyboard again is that I have some great news to report: A very nice gentlemen – who decided to remain anonymous – contacted Chris and me, saying he has some X-MP tapes we might be interested in. As it turned out he has an absolute treasure chest of material, in fact much more than ‘just’ a collection of X-MP tapes. But more on that later.
First a disclaimer though: unfortunately, while I have a copy of some interesting pieces of his collection, I don’t have permission to publish any of the stuff. So this time around I can only show you what it looks like, but I can’t put my work online. To be absolutely precise I can put my work online but it’s pretty useless without the bits that I can’t. Maybe eventually I manage to get the right permissions to publish the full work as well.
What I decided to instead was to put the whole, running simulator on-line. It can be found with login information here: http://cray.modularcircuits.com/
None of the above means of course that I can’t release my own source-code. You can head over to the download page and grab version 2.0, the latest version. It includes the latest sources (of course) and supports the XMP, YMP-el, J90 and SV1 family of machines.
