A new XOP has been added to MDOS to support the TIPI in MDOS mode on the Geneve. The preliminary appendix to the GenREF documentation can be found here. Please note this update is for MDOS Version 7.40 that has not been released as of 4/7/2023. The specifications for the XOP usage were updated and expanded from MDOS version 7.30. Details of the XOP usage in version 7.30 were never released publicly. Should any individual(s) desire details of the XOP code, please contact Beery Miller on AtariAge as user “9640News” and code will be provided. Potential source code usage with minor modification could be to create a library of code for TI-99/4A users for SAMS support.
