Should have mentioned.. it could be a 64*64 matrix with anti-coincidence addressing to
further double it.
Basic testing (via the simple address test listed here:
http://www.psych.usyd.edu.au/pdp-11/hints.html) reveals that most of the 8KW of core
(H215) and controller is working pretty well, except for a 128 byte range between
012000(8) and 012200(8). Within this range, all words read back as all zeros regardless
of what is written.
For 8K the most probable matrix size is 128 * 64 (binary pair closest to the square
root of the size).
