Hi, first, a big "thank you" to all of you who support me with my attempt to get our Explorers and Xerox Stars to run again. I?ll head down to the basement in the afternoon to see if I can build a system that is able to image the Explorer not-quite-SCSI disks (according to the documentation, these have in fact 256 byte sectors). Btw., this Raspberry Pi SCSI device emulator supposedly also supports emulating SASI drives: https://hackaday.com/2017/05/01/the-raspberry-pi-becomes-a-scsi-device/ The original Japanese web page linked in the article is no longer online, but there are several versions of the code (and a translated webpage in English) mirrored on github. This might be useful to build a working SCSI device emulation for the Explorer. So I have another favor related to TI Explorers to ask... One of the reasons (apart from the planned exhibition) I am interested in Lisp and Smalltalk machines is that I?m collecting information on systems using persistent memory, which could also help my students who work on persistent memory research topics to obtain a better insight into the topic and its history. There was a research prototype of a persistent virtual memory system for the TI Explorer by Satish M. Tatte (TI Artificial Intelligence Labs) metioned in these papers: Satish M. Thatte. 1986. Persistent memory: a storage architecture for object-oriented database systems. In Proceedings on the 1986 international workshop on Object-oriented database systems (OODS '86). IEEE Computer Society Press, Washington, DC, USA, 148?159. (https://dl.acm.org/doi/pdf/10.5555/318826.318848) and Thatte S.M. (1991) Persistent Memory: A Storage System for Object-Oriented Databases. In: Dittrich K.R., Dayal U., Buchmann A.P. (eds) On Object-Oriented Database Systems. Topics in Information Systems. Springer, Berlin, Heidelberg. https://doi.org/10.1007/978-3-642-84374-7_16 The second paper cites a more detailed TI Tech Report which I have been unable to find: Thatte, S.M.: "Persistent Memory for Symbolic Computers", Technical Report TR-08-85-21, Central Research Laboratories, Texas Instruments Incorporated, Dallas, TX, July 1985. Does one of you maybe have a copy of this? Best wishes, ??? Michael
