jbdigriz Posted April 15, 2021 Share Posted April 15, 2021 Seller has a (WIP) page documenting the systems these are used in. Suprisingly enough, while they're being phased out and decommissioned by next year, there are some of these DNOS systems still in actual production use. http://rknorman.co.uk/DART and TI990 Documents.html jbdigriz 2 Quote Link to comment Share on other sites More sharing options...

jbdigriz Posted July 11, 2021 Share Posted July 11, 2021 Forgot to mention this earlier, but the documentation Richard supplied is also available on bitsavers.org now in the relevant categories, plus some that Al had on hand but hadn't gotten around to yet. TI stuff listed below. Some of the items would apply to TM990 systems as well. MPP, file io, real time executive, etc. 2021-05-11 04:13:06 ti/terminal/crt/0945423-9801_911_Video_Display_Terminal_Installation_and_Operation_197901.pdf 2021-05-11 02:02:55 ti/terminal/crt/0945424-9701_911_Depot_Maintenance_Manual_197902.pdf 2021-05-11 01:15:42 ti/990/990-12/2250690-9701A_990-10_990-12_Memories_Depot_Maint_198012.pdf 2021-05-10 23:49:04 ti/990/disk/2306140-9701B_WD800A_Installation_and_Operation_198502.pdf 2021-05-10 21:29:20 ti/990/datacomm/2263883-9701_X.21_BCAIM_Installation_and_Operation_198210.pdf 2021-05-10 04:03:26 ti/990/990-10/0945417-9701B_Model_990_10_Computer_System_Hardware_Reference_Manual_198011.pdf 2021-05-10 02:36:04 ti/990/990-10/0945402-9701A_Model_990_10_Computer_System_Field_Maintenance_Manual_198011.pdf 2021-05-09 23:20:48 ti/990/datacomm/0945407-9701_16_Input_16_Output_TTL_Data_Module_Depot_Maintenance_Manual_197608.pdf 2021-05-09 23:11:46 ti/990/datacomm/0945410-9701_Communications_Interface_Module_Depot_Maintenance_Manual_197704.pdf 2021-05-09 22:51:14 ti/990/datacomm/0945408-9701_990_TTY_EIA_Interface_Module_Depot_Maintenace_Manual_197812.pdf 2021-05-09 22:50:24 ti/explorer/999EDCA-A430_Explorer_II_System_Field_Training_Bulletin_198706.pdf 2021-05-09 21:56:37 ti/990/dx10/946289-9701_DX10_3780-2780_Emulators_Guide.pdf 2021-05-09 21:47:23 ti/990/cobol/2270521-9701C_DX10_COBOL_Programmers_Guide.pdf 2021-05-09 21:11:10 ti/990/diagnostics/945400-9701_General_Diagnostic_Information.pdf 2021-05-09 20:31:13 ti/990/diagnostics/945400-9706J_Diagnostics_for_990_Communications_Interfaces.pdf 2021-05-09 20:10:02 ti/990/datacomm/0946240-9701A_Model_990_Computer_TTY-EIA_Terminal_Interface_198012.pdf 2021-05-09 19:58:28 ti/990/dnos/2239980-9901_DNOS_Release_Update_Information_1.3.0.pdf 2021-05-09 19:55:18 ti/990/dnos/2270505-9701_DNOS_Reference_Handbook.pdf 2021-05-09 19:35:20 ti/990/dnos/2270513-9701B_DNOS_SCI_and_Utilities_Design_Document.pdf 2021-05-09 18:47:45 ti/990/dnos/2272088-9701D_DNOS_Permormance_Package_Object_Installation.pdf 2021-05-09 18:46:31 ti/990/dnos/2302607-9901T_DNOS_Release_Information_1.17.0.pdf 2021-05-09 18:45:38 ti/990/pascal/1603730-9701_TI_9900_The_Microprocessor_Pascal_System_1981.pdf 2021-05-09 18:04:36 ti/990/ampl/9900_Device_Independant_File_I-O.pdf 2021-05-09 18:02:38 ti/990/ampl/9900_The_Realtime_Executive_1981.pdf 5 Quote Link to comment Share on other sites More sharing options...
