All, Heinz Lycklama has shared a binder full of old technical memos with Clem Cole, who has scanned them in. Thanks to both of them for preserving these documents. I've just put them at: https://www.tuhs.org/Archive/Documentation/TechReports/Heinz_Tech_Memos/ Here's a list of the documents: A_Minicomputer_Satellite_Processor_System.pdf A_Virtual_Memory_Mini-Computer_System_516-TSS.pdf MM-71-1383-3_Performance_Simulation_and_Measurement_of_a_Virtual_Memory_Multi-progamming_System_for_a_Small_Computer_19710120.pdf MM-72-1353-16_Bus_Interface_in_a_Single_Bus_Multi-processor_Environment_19720920.pdf Office_Communication_Research_in_Lab_135_19770208.pdf TM-74-1352-1_Implementstion_of_Large_Contiguous_Files_and_Asynchronous_IO_in_UNIX_19740104.pdf TM-74-1352-7_Plotting_Facilities_for_Mini-Computer_Systems_19740614.pdf TM-75-1352-2_Emulation_of_UNIX_on_Peripheral_Processors_19750109.pdf TM-75-1352-3_GLANCE_Terminals_on_UNIX_Time-Sharing_19750303.pdf TM-75-1352-4_A_Structured_Operating_System_for_a_PDP-11.45_19750506.pdf TM-75-1352-7_MERT_A_Multi-Environment_Real-Time_Operating_System_19751118.pdf TM-77-1352-1_The_MINI-UNIX_19770103.pdf TM-78-3114-1_UNIX_on_a_Microprocessor_19780322.pdf TM-78-3114-2_A_Minicomputer_Satellite_Processor_System_19780322.pdf TM-78-3114-3_The_MERT_Operating_System_19780422.pdf TM-78-3114-4_The_MERT-UNIX_Supervisor_19780420.pdf TM-78-3114-5_File_System_Structures_for_Real-Time_Applications_19780420.pdf The_MERT_Operating_System.pdf UNIX_on_a_Microprocessor_19780322.pdf Cheers, Warren
