Hi Jeff
 As I recall, there wasn't any OS or anything for these.
They were primarily used to run experimental code on
or blow EPROMs for some other machine. They usually
had enough ROM in them to do things like take data from
a paper tape reader and program proms. They may have had
some form of monitor code as well. They usually had
cards with hardware to emulate the 4001 I/O functions
so that one could debug their code befor commiting to
the mask ROM in the 4001's. Joe R. might have
more info on this machine. It is a collectors item for
sure. I do have some manuals for the MCS-4 series parts
that can help and if you can dump the EPROMs in the machine,
I can disassemble them for you. The EPROMs are most likely
1702A's. These do require some non-standard voltages.
 One can often make up an adapter with an external supply
to read these as though they were 2716 or something on
a standard EPROM programmer.
 I am setup to read and write 1702A's on my 4004 machine.
( not an Intellec-4 ).
 Although, it doesn't talk about the Intellec-4, the
manual I have does sedcribe the 4004. I also have a
newer manual that describe the 4040 as well. I just
sent a copy of the older manual off to one of the other
follows and it cost about $13 to mack copies and send
it to him( as I recall ).
