Looking for a TI technical report on Explorer virtual memory

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:
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.
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.
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?
