I've started to read some of the disks. Does anyone
recognize the following strings? I'm trying to ID the source OS for the following (it
is the ROM source for a Panasonic KX-D4911 terminal).
Here are some of the strings:
IN-III MACRO ASMB. (Z80.ZILOG) VER. 1-01 830131 DATE 60. 1.10 PAGE 1
SYSTEM ANALYZER IN-III VER. 2-2
ISIS
IN-IIIDIN6301
DINZ80B
This was a pretty standard DS/DD 8" disk that read right in using a catweasel and
also with imagedisk. I think it might have been an Intellec-III, but that is based on the
repeated appearance of ISIS, and the fact that it is ROM source.
Any clues?
Thanks,

One thing that I can say with certainty is that Intel never sold a
development system that used double-sided 8" disks. They had a
double-density format (MMFM, rather than MFM that most used) but they
were single-sided. I have several Series II and Series III Intellec
systems and none has double-sided disk drives.
Another observation in the above strings...the Z80.ZILOG isn't Intel.
They never sold anything that supported any Z-80-specific systems. And
ISIS, from Intel, was ISIS-II. Intel would not have left off the "-II"
from their identifiers.
Now, for my guess. This looks like possibly something from a competitor
of Intel, or possibly one of the development systems from Zilog or
National. It is possible they used an ISIS-compatible file format, or
object module format. That may be what the "ISIS" is all about in that
string.
But if you are certain about the DS/DD, then it isn't Intel. SS/DD
could be.
