Jesper: Thanks for posting the scans of the Constructopedia 1.5 last week. The comparison was fascinating, especially finding out what the "new" pieces were in the set. Some debate remains in my mind--has Lego made the RIS set slightly less valuable (...) (26 years ago, 29-Oct-99, to lugnet.robotics)

|

Your semaphore acquire algorithm isn't too good. Here is your code: #define sem_acquire(s) until (s == 0); s = 1; If two tasks are waiting for the semaphore at the same time, it is quite likely that both will get it: // (s is currently nonzero) task (...)

(...) If you look closely at the parts list in 1.0 vs 1.5, you will notice that the composition of pieces has changed in many ways. 1.0 has 26 2x4 bricks, and a couple 2x6 and 2x8 bricks for example. 1.5 has only 5 2x4 bricks, and no 2x6 or 2x8 (...) (26 years ago, 30-Oct-99, to lugnet.robotics)

(...) Maybe they want to get rid of the 1.0 sets, and to encourage that, they are not selling the 1.5 sets just yet. Instead, they will sell you a 1.0 set with a free upgrade. Now if they do that, why can't I get an upgrade for free? -Kekoa (26 years ago, 30-Oct-99, to lugnet.robotics)
