Is there enough memory in the Siemens control to run large programmes? How about the ProtoTRAK?

The standard memory in the Siemens control is 1.2Mb. This is sufficient to run most large programmes but if yours is exceptionally large you may simply insert a PCM/CIA card into the control for capacity far greater than anyone would ever need. The ProtoTRAK SX control also comes standard with 1.2Mb of programme memory with an interface for an optional USB thumb drive of 256Mb or even more.
