Non OTU: If I had to redraw the XBoat routes in the Spinward Marches ...

[mike wightman]

XBoats use Jump-B drives (15 tons) from LBB2.77 to achieve their code: 4, while having no maneuver drive or power plant. This means that the jump drive only requires TL=9. However, to achieve Jump-4, the XBoats need a model/4 computer ... which is TL=10. But, because the engineering section only needs 15 tons of drives, a "standard 100 ton hull" without streamlining can be used for XBoats (making them cheaper).

No, it doesn't. There is no computer size must match jump number rule under 77 rules, all you need is a computer that can run the jump 4 program, which has a size of 2.

Yeah, pretty much. Basically, J-Torps got de-canonized after A4 (Leviathan) and were arguably wrong even there, so if you're going back to a rule-set that allows them you're going back to what sci-fi thought was practical at the time. So, sure -- floppies.

Star Trek original series and other sci fi of the time did not use floppies...

Actually, Star Trek TOS had data block "tapes" almost 20 years before real world computers moved to the 3.5 inch removable media form factor of almost the exact same size.

Star Trek TNG invented the PADD.
Today, Apple sells iPads.

Star Trek may not have "accurately" predicted the future, but boy does the future rhyme well with what Star Trek was doing!
