Hi there, did some worh with rcx/legos/DSM in my thesis which can be found at www.cs.uit.no/~kenne.../Thesis.ps Although i didnt share the memory of each rcx, i installed a dsm server(created at the local university) on a notebook which each rcx (...)

Yes Kekoa it's a bottle neck, as I wrote on the original message, the main idea is to distribute the load, with the MINIMUM amount of network traffic. I think that all the RCX should be connected through fibre optics, in order to implement the (...) (22 years ago, 15-Jan-03, to lugnet.robotics.rcx.legos)

(...) My thought was that the OCRA interrupt could be used as the general 1ms interrupt and the subsystem handler (which is currently using OCRB) could be called every other time from the OCRA handler by using a flag (toggled every 1ms).
