1. I didn't think anyone would make a challenge on this, but, okay:
Auto-Plotted Jumps
For unknown reasons, automated jumps are prone to an increased risk of misjump. A jump plotted by the automatic systems without the involvement of a sentient astrogator is subject to the same DM-4 as all other fully automated actions. For this reason, if just one skilled crewmembers is carried it is usually an astrogator. A jump plotted in semi-automatic mode by someone without the Astrogator skill but with a basic understanding of the concepts involved suffers DM-2. It is thought that a machine will produce several apparently equal solutions to the same jump plot and cannot distinguish between them but a sentient mind somehow ‘feels’ which one is slightly better than the others. Even someone who is not a trained astrogator can do this to some extent and if one is available they can oversee the plot. Their Astrogator skill applies in this case and the DM-2 is not suffered.
Attempting to send a ship through jumpspace without people on board enormously increases the risk of misjump, for reasons unknown. In addition to the DM-4 for the autoplot, a vessel suffers an additional DM-4 if there are no conscious minds aboard. Low berth passengers are by definition not conscious and experiments with highly intelligent but non-sentient minds have produced wildly differing results.

2. Just because you can user older hardware to process newer programmes, doesn't mean that those programmes are available at that level of technology, for whatever reason, canon or otherwise, the game provides.
3. Jump control one is listed at technological level nine, and jump control two at eleven.
4. However, for prototype jump drives, and especially early variants, you couldn't use them at lower technological levels, if the programmes used to activate them weren't available then, and of course, the requisite computers.
5. We could assume that these would be early prototype versions of these programmes, for what could be referred to as alpha and beta testing.
6. The complexity of a jump control one programme appears to be the same as fire control one, both available at technological level nine and requiring the same bandwidth.
