LOTUS CACHE MEMORY DIAGNOSTIC PROGRAM

In reverse-endian from the rest of the file, I found yet another utility:

LOTUS CACHE MEMORY DIAGNOSTIC PROGRAM
REV 1.1  FEB 4,1982

Here's a download of the full binary extraction from the entire Track 0 with the endianness exactly as it was on the tape, and here's a reverse-endian version which more clearly revealed this text.  

This text extract begins at address 0xC2620.


NOTE:  this track of this tape seems to have programming with endianness in both directions, even within the same file (as indicated by my custom filemarks)

Also note, I added my own artistic interpretation to delineate filemarks.  Just search for the text "filemark" in your hex editor/reader (but that only works in the forward-endian version).

Does this give us better clues as to what model, vintage, etc of Microtech machine that these once backed up?

I reversed the endianness of the file on modern Linux, using the command:  

dd if=oldfile.bin of=newfile.bin  conv=swab

And I extracted the text from this Point 4 Data Corp utility, using the command:

strings -a [Filename].bin > [Filename]_Strings.txt

A few weeks later, Bruce Ray provided this manual to compliment this find.  Thank you Bruce! - Point 4 LCM Lotus Cache Memory Software Manual
