...and probably some options from High Guard too
I've been comparing first edition LBB2 with revised, and I think combining the two pays off.
There will also be the occasional item from High Guard, and a couple of house rule variant suggestions.
Hull - same in both editions
Streamlining - same in both editions
Bridge - use the first edition rule, a 20t bridge for all ships, even the ones over 1000t
Computer - use the first edition rule that any computer can be fitted (it isn't limited to model number must equal jump number), but use the revised edition program sizes so that jump programs require 1 space per jump number, and use the revised edition computer model table (with the bis and fib options taken from High Guard first edition).
Drives - use the first edition rule that power plant letter has to be equal to or greater than maneuver drive, but the size of the jump drive doesn't matter. The drives and power plant table is the same in both editions, but I would use the revised edition Drive Potential table (with the house rule variant that extrapolation of the table is allowed for 300t, 500t hulls etc.)
Staterooms, Low Passage Berths, Fuel, Cargo Hold, Hardpoints and turrets, and Ship's Vehicles are all basically the same, but I'd add the Emergency Low Berth from revised edition and the expanded Vehicles list.
Crew requirements - use the revised edition wording for Engineers and Medics.
For military ships High Guard second edition provides:
2t turrets
3t and 5t barbettes
10t bays (from HG 1st ed.)
50t bays
100t bays
armour
nuclear dampers
meson screens
black globes
to which I would add
a CIC
25t bays
sandcaster and laser bays in all the above sizes.
