I have a CPU9000 system with 4 SEMs/LEMs. Three SEM01-M2 boards have been damaged by a surge on the bus but only one LEM01-M2 appears to be damaged. The power supply board of all the SEMs appear to be OK.

Is the SEM01-M2 still available? If not, will the LEM02-M2 work with the SEM01C? Or do I have to replace the SEMs and LEMs and also install the OP03 boards to get the maximum of 16 inputs and 16 outputs for each SEM/LEM pair?
