This software and documentation for the TRS-80 was published by Misosys of Virginia in 1982. MSP-01 (Misosys Support Package 01), developed by Roy Soltoff and Scott A. Loomer, was a collection of four utility programs to enhance the use of LDOS. (LDOS was an 8-bit operating system for Z80 based computers.) The utilities were DOAUTO, DOCONFIG, MEMDIR, and PARMDIR.
