There are several pictures of an 8 KiWord H214 Memory Stack posted on the
Internet, for example, see
At least one DEC manual describes the H214 as having "16 memory mats
arranged in a planar pattern" but the photo referenced above (and many
others) show 20 memory mats arranged in a two x ten planar pattern.
Two by ten is a very strange array for a machine that has a 16 bit word or
18 bits in one with the byte parity option.
Can anyone explain what is going on?
