From the above we assume MASIR(181175) was intended as MASIR ISSUE 4,
although there is no evidence of Elliotts having issued this to users.

The SCRIPTS folder contains scripts to build MASIR(181175).BIN, 
MASIR(ISS3).BIN and LOADER(ISS3).BIN.

Terry Froggatt note on MASIR(181175):

I was reluctant to call my 18/11/75 MASIR "MASIR ISSUE 4" because
I've never seen an official MASIR ISSUE 4 binary tape (then or since).
In fact my 1982 notes say that, subsequently, my 18/11/75 tape
was found to be the same as "18/11/75 Pre-release Issue 4" and
another "ISS 4" tape, neither of which had legible headings.
