Back in the days when DRAM was precious, Intel had
some "8Kx1" DRAMs that
were really "half good" 16K parts. You used the "-x" digit to
determine
There were certainly 32K*1 DRAMs that were half-good 64K chips. IIRC at
least one version of the 48K Spectrum used them, and there was a link on
the board to select which half would be used (obviously all 8 chips had
to be of the same type). I suspect the CoCo1 used them too.
