This is a complete list of operating system configuration variables used by the TS-2068 original ROM. The first version of this document was written using an AERCO disk interface running CP/M in a WordStar word processor.
It contains a detail of each of the variables supported by the original operating system of the ZX Spectrum (TS-2048) and the additional variables used only by the extended operating system of the TS-2068.
All the values of the variables correspond to the cold start of the operating system.
